시멘트 벽체 블록의 제조방법.{MANUFACTURING METHOD OF CEMENT WALL BLOCK}Manufacturing method of cement wall block. {MANUFACTURING METHOD OF CEMENT WALL BLOCK}

본 발명은 벽체 블록의 제조방법에 관한 것으로, 더욱 상세하게는, 건축 폐기물인 유리섬유 및 우레탄폼을 함유함으로써 경량화, 흡음 및 단열 성능을 향상시킨 벽체 블록의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a wall block, and more particularly, to a method for manufacturing a wall block having improved light weight, sound absorption and heat insulation performance by containing glass fiber and urethane foam, which are construction waste.

건축물의 벽체를 시공하기 위한 블록은 경량화를 위하여 경량 기포 콘크리트를 사용하거나 스티로폼과 같은 경량화 재료를 혼합하여 제조하는 것이 일반적이다. 이와 같은 경량화된 벽체 블록은 시공성이 우수하나 소음, 진동, 단열성이 약하여 이를 보강할 필요가 있다.Blocks for constructing walls of buildings are generally manufactured by using lightweight foamed concrete or by mixing lightweight materials such as styrofoam for weight reduction. Such a lightweight wall block has excellent constructability, but has weak noise, vibration, and thermal insulation properties, and thus needs to be reinforced.

예를 들어, 대한민국 등록특허공보 10-1994962호에서는 시멘트와 장석 분체, 석고 분말을 혼합하여 벽체 블록을 제조함으로써 경량화와 함께 소음, 진동, 단열의 효과를 달성하고 있다. 이러한 벽체 블록을 성형하기 위하여 물에 녹는 염 형태의 고화제를 적용하여 장석의 음이온과 결합하면서 시멘트 표면에 대전된 양이온과 결합하여 장석과 시멘트 입자의 결합을 매개하고 있다.For example, in Korean Patent No. 10-1994962, a wall block is manufactured by mixing cement, feldspar powder, and gypsum powder, thereby achieving the effects of noise, vibration, and heat insulation as well as weight reduction. In order to form such a wall block, a water-soluble salt-type solidifying agent is applied to bind to the anions of feldspar and to the cations charged on the cement surface to mediate the bonding between feldspar and cement particles.

따라서 시멘트 벽체 블록의 경량화를 위하여 다른 성분들을 배합할 때에는 각각의 성분들의 결합력에 의해 제조된 벽체 블록의 물성이 결정되기 때문에 이를 위한 성분 및 함량의 최적화가 필요하게 된다.Therefore, when mixing other components for weight reduction of the cement wall block, since the physical properties of the manufactured wall block are determined by the binding force of each component, it is necessary to optimize the components and content for this purpose.

본 발명은 상기와 같은 종래기술의 문제점을 감안하여 안출된 것으로, 건축 폐기물인 유리섬유와 우레탄폼을 재활용하여 시멘트 벽체 블록을 제조하되 시멘트와 유리섬유, 우레탄폼의 결합력을 향상시켜 벽체 블록의 내구성을 향상시킬 수 있는 시멘트 벽체 블록의 제조방법을 제공하는 것을 그 목적으로 한다.The present invention has been devised in view of the problems of the prior art as described above, and by recycling glass fiber and urethane foam, which are construction waste, to manufacture a cement wall block, but improving the bonding strength of cement, glass fiber, and urethane foam to improve the durability of the wall block An object of the present invention is to provide a method for manufacturing a cement wall block that can improve

이하 본 발명에 대하여 상세히 설명한다.Hereinafter, the present invention will be described in detail.

본 발명에 따른 벽체 블록의 제조방법은 시멘트 및 물을 1:0.5 내지 1:1의 부피비로 배합하는 단계, 상기 시멘트 100 중량부에 대하여 유리섬유 10 내지 50 중량부 및 우레탄폼 10 내지 50 중량부를 배합하여 슬러리를 제조하는 단계, 상기 슬러리에 수용성 접착제 5 내지 10 중량부를 배합하여 배합물을 제조하는 단계, 상기 배합물을 형틀에 투입하고 가압 성형하는 단계를 포함하며, 상기 수용성 접착제는 우레탄 수지, 테르펜 수지, 과염소산마그네슘, 과산화수소 및 용제를 포함하는 것을 특징으로 한다.The method for producing a wall block according to the present invention comprises mixing cement and water in a volume ratio of 1:0.5 to 1:1, and 10 to 50 parts by weight of glass fiber and 10 to 50 parts by weight of urethane foam based on 100 parts by weight of the cement. A step of preparing a slurry by mixing, preparing a formulation by mixing 5 to 10 parts by weight of a water-soluble adhesive with the slurry, putting the formulation into a mold and press-molding, wherein the water-soluble adhesive is a urethane resin, a terpene resin , It is characterized in that it contains magnesium perchlorate, hydrogen peroxide and a solvent.

상기 시멘트로는 벽체 블록에 일반적으로 사용되는 시멘트라면 어떠한 것이라도 사용할 수 있으며, 포틀랜드 시멘트 또는 알루미나 시멘트를 사용할 수 있으며, 특히 1종 보통 포틀랜드 시멘트를 사용하는 것이 바람직하다.As the cement, any cement generally used for wall blocks may be used, and Portland cement or alumina cement may be used. In particular, it is preferable to use type 1 ordinary Portland cement.

상기 유리섬유 및 우레탄폼은 비중이 작은 소재로서 시멘트와 배합하여 성형체를 구성할 때 성형체의 경량화를 위하여 사용되고 있는 소재이다. 본 발명에서는 상기 유리섬유 및 우레탄폼을 건축물의 단열재나 보드 등의 건축 폐기물로부터 발생하는 폐기물로부터 얻고 있는데, 이를 통해 건축 폐기물의 재활용을 통해 벽체 블록을 제조할 수 있게 된다.The glass fiber and urethane foam are materials with a small specific gravity and are used to reduce the weight of the molded body when it is mixed with cement to form a molded body. In the present invention, the glass fiber and urethane foam are obtained from waste generated from building waste such as insulation or board of a building, and through this, a wall block can be manufactured by recycling the building waste.

상기 유리섬유 및 우레탄폼은 시멘트와 물의 혼합물에 투입하는 공정을 통해 배합되는데, 상기 시멘트와 물은 1:0.5 내지 1:1의 부피비로 배합함으로써 상기 혼합물의 적당한 점성을 확보한 후 상기 유리섬유 및 우레탄폼을 투입하는 것이 바람직하다.The glass fiber and the urethane foam are blended through a process of putting in a mixture of cement and water, and after securing an appropriate viscosity of the mixture by mixing the cement and water in a volume ratio of 1:0.5 to 1:1, the glass fiber and It is preferable to put urethane foam.

상기 유리섬유 및 우레탄폼은 각각 10 내지 50 중량부의 함량으로 배합되는데 유리섬유 및 우레탄폼의 함량이 증가할수록 벽체 블록의 경량화 정도가 증가하나 반면 벽체 블록의 내구성이 저하되는 문제점이 발생할 수 있다. 또한, 유리섬유 및 우레탄폼의 함량이 지나치게 적은 경우 벽체 블록의 성형에는 유리하나 경량화된 블록을 얻을 수 없고 차음효과나 단열효과도 불충분한 것으로 나타났다.The glass fiber and the urethane foam are each blended in an amount of 10 to 50 parts by weight, and as the content of the glass fiber and the urethane foam increases, the degree of weight reduction of the wall block increases, whereas the durability of the wall block decreases. In addition, when the content of glass fiber and urethane foam is too small, it is advantageous for the molding of the wall block, but a lightweight block cannot be obtained, and the sound insulation effect or heat insulation effect is insufficient.

상기 유리섬유 및 우레탄폼은 분쇄한 분말 형태로 혼합되는데, 이때 상기 유리섬유 및 우레탄폼은 100 내지 300 메쉬의 크기로 분쇄하여 사용하는데, 이를 통해 상기 시멘트와 물의 혼합물에 대한 분산성이 향상될 수 있다. 그러나 건축 폐기물인 유리섬유와 우레탄폼은 불순물을 함유하고 있으며 시멘트와의 상용성이 낮기 때문에 이를 혼합하여 성형하는 경우 블록의 물성이 저하되는 문제점이 발생한다.The glass fiber and the urethane foam are mixed in the form of a pulverized powder, in which case the glass fiber and the urethane foam are pulverized to a size of 100 to 300 mesh, through which the dispersibility of the cement and water mixture can be improved. have. However, since glass fiber and urethane foam, which are construction wastes, contain impurities and have low compatibility with cement, there is a problem in that the physical properties of the block are deteriorated when mixed and molded.

따라서 상기 시멘트, 유리섬유, 우레탄폼을 혼합한 슬러리에 수용성 접착제를 부가하여 배합물을 제조한 후 이를 성형하여 블록을 제조하게 된다.Therefore, the mixture is prepared by adding a water-soluble adhesive to the slurry in which the cement, glass fiber, and urethane foam are mixed, and then a block is manufactured by molding it.

또한, 상기 슬러리를 제조하는 단계에서 인조대리석 및 폴리염화비닐(PVC) 중 어느 하나 또는 이들의 혼합물 10 내지 50 중량부를 추가적으로 포함함으로써 제조된 블록의 물성을 향상시킬 수도 있다. 인조대리석 및 폴리염화비닐은 분쇄된 분말 또는 비드 형태로 포함되는데, 상기 폴리염화비닐은 폴리염화비닐의 폐기물을 재활용할 수도 있다. 이 경우 폐기물인 폴리염화비닐을 녹인 후 이를 비드로 가공하여 사용할 수 있다.In addition, the physical properties of the manufactured block may be improved by additionally including 10 to 50 parts by weight of any one of artificial marble and polyvinyl chloride (PVC) or a mixture thereof in the step of preparing the slurry. Artificial marble and polyvinyl chloride are included in the form of pulverized powder or beads, and the polyvinyl chloride may be recycled as waste of polyvinyl chloride. In this case, the waste polyvinyl chloride can be melted and processed into beads for use.

상기 수용성 접착제는 5 내지 10 중량부의 함량으로 배합되는데, 상기 수용성 접착제의 배합량이 지나치게 적으면 상용성이 떨어지는 유리섬유와 우레탄폼 분말이 시멘트에 충분히 분산되지 못하여 제조된 벽체 블록의 내구성이 저하되며, 상기 수용성 접착제의 배합량이 지나치게 많으면 성형성이 저하되고 제조된 벽체 블록이 부분적으로 뭉치는 현상이 발생하여 강도가 약해지는 문제점이 발생한다.The water-soluble adhesive is formulated in an amount of 5 to 10 parts by weight. If the amount of the water-soluble adhesive is too small, the glass fiber and urethane foam powder having poor compatibility are not sufficiently dispersed in the cement, thereby reducing the durability of the manufactured wall block, If the blending amount of the water-soluble adhesive is too large, moldability is deteriorated, and a phenomenon in which the manufactured wall block is partially agglomerated occurs, thereby causing a problem in which the strength is weakened.

상기 수용성 접착제로는 우레탄 수지, 테르펜 수지, 과염소산마그네슘, 과산화수소 및 용제를 포함하는 접착제 조성물을 사용하는데, 특히, 우레탄 수지 100 중량부에 대하여, 테르펜 수지 5 내지 10 중량부, 아크릴산 5 내지 10 중량부, 과염소산마그네슘 1 내지 5 중량부 및 용제 10 내지 50 중량부를 포함하도록 하는 것이 바람직하다.As the water-soluble adhesive, an adhesive composition comprising a urethane resin, a terpene resin, magnesium perchlorate, hydrogen peroxide and a solvent is used. In particular, based on 100 parts by weight of the urethane resin, 5 to 10 parts by weight of a terpene resin, 5 to 10 parts by weight of acrylic acid , it is preferable to include 1 to 5 parts by weight of magnesium perchlorate and 10 to 50 parts by weight of the solvent.

상기 우레탄 수지는 접착제를 구성하는 베이스 수지로서 우레탄폼 및 시멘트와의 상용성이 우수하다. 또한, 상기 우레탄 수지를 베이스 수지로 하여 테르펜 수지를 5 내지 10 중량부의 범위로 배합하는데, 상기 테르펜 수지는 점착제 등에 사용되는 탄화수소 수지인데, 로진계 수지와 마찬가지로 천연 수지로서 로진계 수지를 사용할 때에 비해 점착력 및 상용성이 더 우수하여 시멘트 입자와 유리섬유, 우레탄폼 분말의 결합력을 향상시키는 것으로 나타났다. 상기 테르펜 수지의 함량이 지나치게 적거나 지나치게 많으면 벽체 블록을 성형한 후 강도가 불충분하여 충격에 의해 쉽게 파손되거나 부분적인 파손이 발생할 가능성이 높아지는 것으로 나타났으며, 상기 범위에서 접착제에 함유될 때 최적의 효과를 나타내는 것을 확인하였다.The urethane resin is a base resin constituting the adhesive, and has excellent compatibility with urethane foam and cement. In addition, the urethane resin is used as the base resin and the terpene resin is blended in the range of 5 to 10 parts by weight, and the terpene resin is a hydrocarbon resin used in adhesives, etc., as compared to when using a rosin-based resin as a natural resin like the rosin-based resin. It has been shown to improve the bonding strength between cement particles, glass fibers, and urethane foam powder due to better adhesion and compatibility. It was found that if the content of the terpene resin is too small or too large, the strength is insufficient after molding the wall block, and the possibility of easily breaking or partial damage by impact increases, and when contained in the adhesive in the above range, the optimum It was confirmed that the effect was shown.

또한, 상기 접착제는 산 성분과 염기 성분을 함께 포함함으로써 성형 공정에서 열 또는 압력 등의 외력이 작용하면 입자 간 결합력을 향상시킬 수 있는 반응 촉진의 역할을 하게 된다. 이러한 효과를 고려하여 상기 접착제는 아크릴산 및 과염소산마그네슘(magnesium perchlorate)을 포함하게 되는데, 상기 과염소산마그네슘은 pKa가 -6.9의 강산 물질이며, 과산화수소는 pKa가 11.75의 염기성 물질로서 이를 함유함으로써 접착제의 입자 간 결합력이 크게 향상되는 것으로 나타났다.In addition, since the adhesive includes an acid component and a base component together, when an external force such as heat or pressure is applied in the molding process, the adhesive serves to promote a reaction capable of improving the bonding force between the particles. In consideration of this effect, the adhesive includes acrylic acid and magnesium perchlorate. The magnesium perchlorate is a strong acid material having a pKa of -6.9, and hydrogen peroxide is a basic material having a pKa of 11.75. It was found that the bonding strength was significantly improved.

상기 용제로는 아세톤 및 디메틸카보네이트의 혼합 용제를 사용하는 것이 바람직하다. 이는 강산인 과염소산마그네슘이 물에서는 용해도가 높으나 혼합 용제를 사용할 경우 용해도가 저하되어 배합물을 제조하기 전까지는 안정적으로 혼합된 상태를 유지하다가 배합물을 제조하는 과정에서 물과 접촉할 때 반응성을 증가시키도록 하기 위한 것이다. 상기 혼합 용제로는 아세톤 및 디메틸카보네이트를 1:4 내지 1:1의 중량비로 혼합하는 것이 바람직한데, 상기 배합비에서 접착제의 산 성분과 염기 성분을 안정화시킬 수 있는 것으로 나타났다.It is preferable to use a mixed solvent of acetone and dimethyl carbonate as the solvent. This is because magnesium perchlorate, a strong acid, has high solubility in water, but when a mixed solvent is used, the solubility is lowered, so that the mixture is stably maintained until the formulation is prepared. it is to do As the mixed solvent, it is preferable to mix acetone and dimethyl carbonate in a weight ratio of 1:4 to 1:1, and it was found that the acid component and the base component of the adhesive can be stabilized at the mixing ratio.

따라서 과염소산마그네슘과 과산화수소를 단순히 혼합시키면 중화되면서 반응열이 발생하여 비활성화되나 상기 혼합 용제와 배합한 상태에서는 배합물을 제조하는 단계까지 안정적으로 접착제 조성물을 유지할 수 있는 것으로 나타났다.Therefore, when magnesium perchlorate and hydrogen peroxide are simply mixed, heat of reaction is generated while being neutralized and deactivated.

또한, 상기 접착제 조성물은 베이스 수지인 우레탄 수지 및 접착력을 향상시키기 위한 테르펜 수지가 시멘트, 유리섬유, 우레탄폼 입자와 접착되어 충분한 결합력을 얻을 수 있도록 상기 접착제 조성물에 함유된 과염소산마그네슘과 과산화수소의 상호작용에 의해 제조된 벽체 블록의 내구성을 향상시킬 수 있게 된다.In addition, in the adhesive composition, the urethane resin as the base resin and the terpene resin for improving adhesion are adhered to cement, glass fiber, and urethane foam particles to obtain sufficient bonding strength. The interaction of magnesium perchlorate and hydrogen peroxide in the adhesive composition It becomes possible to improve the durability of the wall block manufactured by

또한, 상기 배합물을 형틀에 투입하고 가압 성형하는 단계는 통상의 압축 성형법을 적용할 수 있는데, 0.1 내지 20 t/㎡의 압력을 30초 내지 1분 간 가하면 성형체인 벽체 블록을 제조할 수 있다.In addition, in the step of putting the compound into a mold and press-molding, a conventional compression molding method can be applied, and when a pressure of 0.1 to 20 t/m is applied for 30 seconds to 1 minute, a wall block as a molded body can be manufactured.

본 발명에 따른 제조방법의 효과를 확인하기 위하여 다음과 같이 시제품을 제조하여 시험평가를 실시하였다.In order to confirm the effect of the manufacturing method according to the present invention, a prototype was prepared as follows and test evaluation was performed.

수용성 접착제로는 우레탄 수지 100 중량부, 테르펜 수지 8 중량부, 과염소산마그네슘 1.5 중량부, 과산화수소 7 중량부 및 아세톤과 디메틸카보네이트를 1:2의 중량비로 혼합한 혼합 용제 20 중량부를 리본 혼합기를 이용하여 혼합함으로써 접착제 조성물을 제조하여 이를 사용하였다.As the water-soluble adhesive, 100 parts by weight of urethane resin, 8 parts by weight of terpene resin, 1.5 parts by weight of magnesium perchlorate, 7 parts by weight of hydrogen peroxide, and 20 parts by weight of a mixed solvent obtained by mixing acetone and dimethyl carbonate in a weight ratio of 1:2 using a ribbon mixer An adhesive composition was prepared and used by mixing.

또한, 유리섬유 및 우레탄폼은 건축 자재의 폐기물에서 회수한 유리섬유 및 우레탄폼을 분쇄하여 분급함으로써 150 메쉬의 분말을 제조하였다.In addition, glass fibers and urethane foam were prepared by grinding and classifying glass fibers and urethane foam recovered from the waste of building materials to prepare a 150 mesh powder.

1종 보통 포틀랜드 시멘트와 증류수를 1:0.6의 부피비로 리본 혼합기에 투입하고 혼합한 후 여기에 유리섬유 분말 20 중량부 및 우레탄폼 분말 20 중량부를 투입하고 이를 30분 간 배합하여 시멘트 슬러리를 제조하였다. 제조된 시멘트 슬러리에 8 중량부의 접착제 조성물을 투입하고 30분 간 배합하여 배합물을 제조하였다. 제조된 배합물을 형틀에 투입하고 10 t/㎡의 압력으로 30초 간 가압하여 성형체를 제조하였고, 상기 성형체를 건조하여 390×190×15㎜의 벽체 블록을 제조하였다(실시예).Type 1 ordinary Portland cement and distilled water were put into a ribbon mixer in a volume ratio of 1:0.6 and mixed, and then 20 parts by weight of glass fiber powder and 20 parts by weight of urethane foam powder were added thereto, and the mixture was mixed for 30 minutes to prepare a cement slurry. . 8 parts by weight of the adhesive composition was added to the prepared cement slurry and blended for 30 minutes to prepare a formulation. The prepared compound was put into a mold and pressed at a pressure of 10 t/m 2 for 30 seconds to prepare a molded body, and the molded body was dried to prepare a wall block of 390×190×15 mm (Example).

또한, 비교를 위하여 실시예와 동일한 방법으로 벽체 블록을 제조하되 초산비닐-아세트산 공중합체를 함유하는 수용성 접착제(대흥화학, D-410)를 10 중량부 배합하여 벽체 블록을 제조하였다(비교예 1).In addition, for comparison, a wall block was prepared in the same manner as in Example, but 10 parts by weight of a water-soluble adhesive (Daeheung Chemical, D-410) containing a vinyl acetate-acetic acid copolymer was mixed to prepare a wall block (Comparative Example 1) ).

또한, 실시예와 동일한 방법으로 벽체 블록을 제조하되 수용성 접착제를 혼합하지 않고 시멘트 슬러리를 성형하여 벽체 블록을 제조하였다(비교예 2).In addition, a wall block was prepared in the same manner as in Example, but a cement slurry was formed without mixing a water-soluble adhesive to prepare a wall block (Comparative Example 2).

제조된 벽체 블록에 대하여 KS F 2405에 따라 압축강도를 측정한 결과, 실시예는 35 MPa로 나타났으나, 비교예 1에서는 30 MPa, 비교예 2에서는 22 MPa로 실시예의 벽체 블록에서 높은 압축강도 특성을 나타내는 것으로 나타났다. 특히, 비교예 2에서는 압축강도가 현저히 낮게 나타났는데, 이는 벽체 블록 성형 시 접착제를 혼합하지 않으면 제조된 벽체 블록의 충분한 강도 및 내구성을 확보할 수 없음을 시사하는 결과이다.As a result of measuring the compressive strength of the manufactured wall block according to KS F 2405, the Example showed 35 MPa, but in Comparative Example 1 it was 30 MPa, and in Comparative Example 2 it was 22 MPa. appeared to be characteristic. In particular, in Comparative Example 2, the compressive strength was significantly low, which suggests that sufficient strength and durability of the manufactured wall block cannot be secured unless an adhesive is mixed during the wall block molding.

또한, 상온에서 동일한 용적의 밀폐된 하우징에 벽체 블록을 두고 일측면을 5시간 동안 직사광에 노출시킨 후 이를 적외선 온도계로 측정하여 표면의 온도변화를 확인하였다. 측정 전 벽체 블록은 표면 온도가 17.5℃(표준편차 0.5℃)였다. 직사광 노출 후 측정한 결과 실시예의 벽체 블록은 표면 온도가 19.2℃로 상승하였으나, 비교예 1은 25.1℃, 비교예 2는 24.8℃까지 상승하였다. 이러한 결과는 실시예의 벽체 블록이 단열 성능이 더 우수한 것을 나타내는 결과인데, 벽체 블록 성형 과정에서 사용되는 수용성 접착제가 각 입자 간의 충분한 결합력을 확보하기 때문에 나타나는 결과로 추측된다.In addition, a wall block was placed in a sealed housing of the same volume at room temperature, and one side was exposed to direct sunlight for 5 hours, and then the temperature change of the surface was confirmed by measuring it with an infrared thermometer. The surface temperature of the wall block before measurement was 17.5°C (standard deviation 0.5°C). As a result of measurement after exposure to direct sunlight, the surface temperature of the wall block of Example increased to 19.2 °C, but in Comparative Example 1 it rose to 25.1 °C and Comparative Example 2 to 24.8 °C. These results indicate that the wall block of the example has better thermal insulation performance, and it is presumed that the result is because the water-soluble adhesive used in the wall block molding process secures sufficient bonding strength between each particle.

또한, 벽체 블록에 대하여 KS F 2810(건축물의 현장 바닥 충격음 측정방법)에 따라 경량 충격음 레벨을 측정하였다. 15㎜의 벽체 블록 두께를 기준으로 63 Hz의 주파수에서 실시예는 38 dB의 충격음 레벨을 나타내었으나, 비교예 1은 45 dB, 비교예 2는 48 dB를 나타내어 실시예의 벽체 블록이 향상된 흡음 성능을 나타내는 것을 확인할 수 있었다.In addition, the light-weight impact sound level was measured for the wall block according to KS F 2810 (Method for measuring the impact sound on the floor of a building). At a frequency of 63 Hz based on a wall block thickness of 15 mm, the Example showed an impact sound level of 38 dB, but Comparative Example 1 showed 45 dB and Comparative Example 2 showed 48 dB, so that the wall block of the Example exhibited improved sound absorption performance. could be seen to indicate.

이와 같은 시험결과로부터 본 발명에 따른 벽체 블록의 제조방법은 건축 폐기물인 유리섬유 및 우레탄폼을 이용하여 벽체 블록을 제조함으로써 경량화 및 흡음, 단열 성능을 향상시킬 수 있는 것을 확인할 수 있다.From these test results, it can be confirmed that the method for manufacturing a wall block according to the present invention can improve light weight, sound absorption, and thermal insulation performance by manufacturing a wall block using glass fiber and urethane foam, which are construction waste.
