이하 본 발명에 대하여 보다 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail.
본 발명은 제지애시와 활성화제를 혼합하며, 활성화제로 중성 또는 알칼리성의 활성화제를 단독 또는 혼합하여 사용함에 따라, CSH 겔(C=CaO, S=SiO2, H=H2O)을 형성하거나 무기폴리머(Si-O-Al-O 중합체) 즉, 폴리시알레이트 반응물질을 형성함으로써 시멘트를 사용하지 않고도 우수한 강도를 발현하며, 구조체를 제조할 수 있는 모르타르 조성물에 관한 것이다.The present invention mixes paper ash and the activator, and forms a CSH gel (C = CaO, S = SiO 2 , H = H 2 O) by using a neutral or alkaline activator alone or mixed as an activator. By forming an inorganic polymer (Si-O-Al-O polymer), that is, a polysialate reactant, the present invention relates to a mortar composition capable of producing a structure by expressing excellent strength without using cement.
본 발명에서 사용되는 제지애시는 CaO 30 ~ 60 중량%, SiO2 13 ~ 20 중량%, Al2O3 5 ~ 10 중량%, Fe2O3 5 ~ 6 중량%, MgO 6 ~ 7 중량%를 포함한다. 보다 구체적으로는 CaO 30 ~ 45 중량%, SiO2 13 ~ 20 중량%, Al2O3 5 ~ 10 중량%, Fe2O3 5 ~ 6 중량%, MgO 6 ~ 7 중량%, 기타 15 ~ 17 중량%를 포함한다. 상기 기타는 미량의 원소를 의미하는 것으로, 상기 함량은 미량의 원소의 합을 의미한다.The papermaking ash used in the present invention may contain 30 to 60% by weight of CaO, 13 to 20% by weight of SiO 2 , 5 to 10% by weight of Al 2 O 3 , 5 to 6% by weight of Fe 2 O 3 , and 6 to 7% by weight of MgO. Include. More specifically, CaO 30 to 45% by weight, SiO 2 13 to 20% by weight, Al 2 O 3 5 to 10% by weight, Fe 2 O 3 5 to 6% by weight, MgO 6 to 7% by weight, other 15 to 17 Contains by weight. The other means a trace element, and the content refers to the sum of the trace elements.
본 발명에서 사용되는 제지애시는 상기의 성분과 같이 국내에서 발생하는 F급 플라이애시나 버텀애시와는 달리 자체적으로 수화반응을 일으켜 칼슘 실리케이트 하이드레이트 겔(CSH gel)과 수산화칼슘과 같은 수화물을 생성시켜 강도발현이 가능함을 알게되어 본 발명을 완성하였다. The paper ash used in the present invention, unlike the F-type fly ash or bottom ash, which occurs in Korea as described above, generates a hydration reaction by itself to generate hydrates such as calcium silicate hydrate gel (CSH gel) and calcium hydroxide It was found that expression is possible to complete the present invention.
그 함량은 전체 결합재 조성물 중 20 ~ 80 중량%를 사용하는 것이 바람직하다. 20 중량% 미만일 경우에는 강도가 약하며, 80 중량%를 초과하는 경우에도 모르타르의 부피가 지나치게 증가되어 단위면적당 압축강도 저하 등의 문제가 발생한다.The content is preferably used 20 to 80% by weight of the total binder composition. If it is less than 20% by weight, the strength is weak, and even if it exceeds 80% by weight, the volume of mortar is excessively increased, causing problems such as a decrease in compressive strength per unit area.
본 발명은 상기 제지애시와 함께 활성화제를 사용하는데 특징이 있으며, 이러한 활성화제는 제지애시와 반응하여 Si-O-Al-O 중합체를 형성하는 촉매제로, 중성촉진제와 알칼리촉진제를 단독으로 사용하거나 혼합하여 사용하는 것이 바람직하 다. 그 함량은 활성화제(반응촉진제) 0.01 ~ 20 중량%를 사용하는 것이 바람직하다. 0.01 중량% 미만으로 사용하는 경우 반응성이 낮아 Si-O-Al-O 중합체의 형성이 곤란하며, 20 중량%를 초과하여 사용하는 경우 조성물의 비빔 직후 급격한 반응에 의해 가사시간의 확보가 곤란하다.The present invention is characterized in that an activator is used together with the papermaking ash, and the activator is a catalyst that reacts with the papermaking ash to form a Si-O-Al-O polymer, or a neutral accelerator and an alkali accelerator are used alone. It is preferable to use the mixture. The content is preferably used 0.01 to 20% by weight of the activator (reaction accelerator). When used at less than 0.01% by weight, it is difficult to form a Si-O-Al-O polymer due to low reactivity, and when used at more than 20% by weight, it is difficult to secure pot life due to a rapid reaction immediately after the composition is beamed.
상기 활성화제는 예를 들어, 중성촉진제로는 pH가 6~9인 구연산칼륨(Potassium citrate), 구연산칼슘(Calcium citrate), 구연산나트륨(Sodium citrate), 말산(Malic acid), 질산칼슘(Calcium nitrate), 말론산(Malonic acid), 글리콜산(Glycolic acid) 또는 이들의 염 등이 사용 가능하다. 또한 알칼리촉진제로는 수산화나트륨, 수산화칼슘, 수산화칼륨, 수산화마그네슘, 수산화바륨, 탄산나트륨, 탄산칼륨, 탄산수소나트륨, 탄산수소칼륨, 탄산마그네슘, 탄산칼슘, 알칼리 금속 탄산염의 수화물, 알칼리 토금속 탄산염, 알칼리 토금속 탄산염의 수화물, 규산나트륨, 규산칼륨, 리튬실리케이트 등이 사용 가능하다. For example, the activator may include, for example, potassium citrate, calcium citrate, sodium citrate, malic acid, malic acid, calcium nitrate, and the like having a pH of 6-9. ), Malonic acid, glycolic acid, or salts thereof may be used. Alkali accelerators include sodium hydroxide, calcium hydroxide, potassium hydroxide, magnesium hydroxide, barium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, magnesium carbonate, calcium carbonate, alkali metal carbonate hydrates, alkaline earth metal carbonates, alkaline earth metals Hydrates of carbonate, sodium silicate, potassium silicate, lithium silicate and the like can be used.
보통의 애시는 물과 접촉하면 미량의 CaO 성분이 우선적으로 용출하고 표면이 SiO2, Al2O3 성분으로 가득 찬 비정질 생성층이 형성되어 반응의 진행을 저해하며 이러한 불투수성의 산성피막은 강알칼리에 의해 피막을 파괴하여야만 반응이 계속 진행 된다. 그러나 본 발명에서 이용되는 제지애시는 CaO 성분이 약 30~45 중량% 정도 포함되어 있으므로 용출된 다량의 CaO가 pH를 상승시켜 SiO2, Al2O3 성분을 자체적으로 자극하여 칼슘 실리케이트 하이드레이트 겔(CSH gel)과 같은 수화물을 장시간에 걸쳐 형성시켜 강도를 발현한다.When ordinary ashes come into contact with water, trace amounts of CaO components are eluted preferentially, and an amorphous formation layer filled with SiO 2 and Al 2 O 3 components forms a reaction to inhibit the progress of the reaction. The reaction continues only when the film is destroyed. However, since the paper ash used in the present invention contains about 30 to 45% by weight of CaO component, a large amount of eluted CaO raises the pH to stimulate the SiO 2 , Al 2 O 3 component itself to cause calcium silicate hydrate gel ( Hydrates such as CSH gel) are formed over a long time to express strength.
상기의 중성, 알칼리 활성화제는 단독 혹은 혼합 사용되어 상기의 반응을 촉진시켜 제지애시 모르타르의 조기강도 및 고강도를 발현시킨다.The neutral and alkali activators are used alone or in combination to promote the reaction to develop early strength and high strength of paper ash mortar.
또한 알칼리 활성화제 사용 시 두 가지 종류의 반응 메커니즘이 발생한다. 첫째, 실리코 알루미네이트의 용해 반응이 일어나는데, 이는 겔 형성 및 중축합반응과 동시에 진행하여 결과적으로 폴리시알레이트(polysialate)라고 하는 중합체 Si-O-Al-O 결합이 형성된다. 폴리시알레이트의 형성으로 제지애시 모르타르의 응결 및 강도발전이 이루어진다. 둘째로, 제지애시의 잠재적인 수경(hydraulic) 성질로 CaO 및 SiO2는 물과 반응하여 시멘트의 특질을 지닌 CSH 겔(C=CaO, S=SiO2, H=H2O)을 형성한다. CSH 겔의 형성은 초기 단계에서 응결시간을 가속시키고 추후 단계에서 강도 발전에 기여한다. In addition, two kinds of reaction mechanisms occur when using alkali activators. First, a dissolution reaction of the silicon aluminate occurs, which proceeds simultaneously with the gel formation and polycondensation reactions, resulting in the formation of a polymer Si-O-Al-O bond called polysialate. Formation of polysialate results in coagulation and strength development of paper ash mortar. Second, due to the potential hydraulic properties of paper ash, CaO and SiO 2 react with water to form CSH gels (C = CaO, S = SiO 2 , H = H 2 O) with the properties of cement. Formation of the CSH gel accelerates the settling time in the early stages and contributes to strength development in later stages.
상기 모래는 모르타르에서 충전재의 역할을 담당하며, 치수(입경) 제한은 없다. 함량은 바람직하게는 결합재 조성물 전체 함량 중 10 ~ 70 중량% 범위로 사용한다. 10 중량% 미만일 경우에는 경화체의 수축을 억제하는 효과가 미미하여 건조수축량이 증대될 우려가 있으며, 비경제적이다. 70 중량% 초과일 경우에는 충전재량이 과도해져 유동성 및 시공성이 저하된다.The sand plays the role of filler in mortar, and there is no limitation on the size (particle size). The content is preferably used in the range of 10 to 70% by weight of the total content of the binder composition. If it is less than 10% by weight, the effect of suppressing the shrinkage of the cured body is insignificant, which may increase the amount of dry shrinkage, which is uneconomical. If it is more than 70% by weight, the amount of filler is excessive and fluidity and workability are reduced.
또한, 상기 모래의 함량 중 1 ~ 50 중량%를 운모석, 장석, 맥반석, 게르마늄, 세리사이트, 일라이트, 천매암, 황토, 제올라이트, 펄라이트, 질석으로 이루어진 군으로부터 단독 또는 2종 이상 선택된 분말로 대체하여 사용할 수 있다.In addition, 1 to 50% by weight of the content of the sand is replaced with a powder selected solely or two or more from the group consisting of mica, feldspar, ganban stone, germanium, sericite, illite, natural stone, loess, zeolite, pearlite, vermiculite Can be used.
상기 모래의 일부를 대신하여 첨가되는 운모석, 장석, 맥반석, 게르마늄, 세 리사이트, 일라이트, 천매암, 황토는 음이온의 방출로 인해 면역력 향상, 정신안정, 생리기능 향상 등의 효과가 있고, 원적외선이 다량 방출되어 세포의 활성화, 혈액정화, 피로회복 등의 효과를 볼 수 있으며, 건조시의 강도를 향상시키고 균열을 방지하는 기능을 하게 된다. 또한 제올라이트, 펄라이트, 질석은 탈취, 단열, 보온, 내화 등의 기능을 부가한다. Mica, feldspar, elvan, germanium, sericite, illite, chalcedony, and ocher added in place of a part of the sand have an effect of improving immunity, mental stability, and physiological function due to the release of negative ions, and far infrared rays. The large amount is released and the effects of cell activation, blood purification, fatigue recovery, etc. can be seen, and the function of improving the strength during drying and preventing cracks. In addition, zeolite, pearlite and vermiculite add functions such as deodorization, heat insulation, thermal insulation and fire resistance.
또한, 상기 결합재 조성물은 첨가제로 수지, 분산제, 소포제, 지연제, 증점제로부터 선택되는 어느 하나 또는 둘 이상을 더 포함할 수 있다. 구체적으로 수지 0.1~5 중량%, 분산제 0.1~10 중량%, 소포제 0.01~3 중량%, 지연제 0.01~10 중량%, 증점제 0.01~3 중량%가 더 포함될 수 있다.In addition, the binder composition may further include any one or two or more selected from a resin, a dispersant, an antifoaming agent, a retardant, and a thickener as an additive.

상기 분산제는 모르타르의 입자표면에 흡착하여 입자표면에 전하를 주어 입자들끼리 상호 반력을 일으키므로, 응집된 입자를 분산시켜 유동을 증가시켜 감수효과로 인한 강도 증진이 가능하게 한다. 상기 분산제로서는 통상의 감수제를 사용할 수 있다. 예를 들어 리그닌술포네이트, 폴리나프탈렌술포네이트, 폴리멜라민술포네이트 또는 폴리카복실레이트계 감수제로 이루어진 군으로부터 단독 또는 둘 이상 혼합사용이 가능하다. 본 조성물에 있어서 분산제의 함량은 0.1~10 중량부를 사용하는 것이 바람직하며, 0.1 중량% 미만으로 사용하는 경우 상기 성능발현이 이루어지지 않으며, 10 중량%를 초과하는 경우 과다 사용으로 인해 모르타르 점성이 저하하여 재료분리가 발생되는 단점을 지닌다.Since the dispersant is adsorbed on the particle surface of the mortar and gives charge to the particle surface to cause mutual reaction between the particles, it is possible to increase the flow by dispersing the aggregated particles to increase the strength due to the sensitization effect. As the dispersant, ordinary water reducing agents can be used. For example, lignin sulfonate, polynaphthalene sulfonate, polymelamine sulfonate, or a polycarboxylate-based group may be used alone or in combination of two or more. In the present composition, the content of the dispersant is preferably used in an amount of 0.1 to 10 parts by weight, and when used in an amount of less than 0.1% by weight, the above-described performance is not achieved. This has the disadvantage that material separation occurs.

In the present invention, the alpha-type hemihydrate gypsum is synthesized from a flue gas desulfurization gypsum or phosphate gypsum produced as a natural dihydrate gypsum or by-product gypsum using a pressurized steam method or a pressurized hydrothermal method at a temperature of 100 to 150 ° C. It is able to express stable initial shrinkage and excellent initial strength and stable long-term strength maintenance performance compared to general cement composition, without plastic shrinkage, and control of condensation time by water ratio control. Not only is it possible to achieve a high initial fluidity, but also has excellent workability in irregularly shaped cross sections. In addition, unlike the existing cement composition, since the alkalinity is not high, there is little concern about neutralization, and there is an advantage of ensuring stable durability from the wet and dry repeat action and freeze-thawing action by securing a certain level of durable voids. Beta-type half-hydrate gypsum is produced from natural dehydrated gypsum or by-products from flue gas desulfurized gypsum or phosphate dihydrate gypsum using simple firing, atmospheric solution method, and microwave method. But may contribute to the shrinkage of the paper ash binder. Anhydrous gypsum is used as a natural and industrial by-products and reacts with paper ash hydrates for a long time to produce ettringite, contributing to the increase of long-term strength.

After pouring into each mold, it was poured after 24 hours and wetted until 28 days of age (temperature 20 ± 3 ℃, RH 80 ± 10%) was carried out to prepare a specimen. In addition, the physical properties of the composition were measured as shown in Table 3 below.

[표 3] [Table 3]
상기 표에서 보이는 바와 같이, 실시예 1과 2는 시멘트 대신 제지애시와 중성 활성화제 단독 또는 알칼리 활성화제와 혼합 사용함으로써 비교예 1에 비하여 경화속도가 단축되어 초기강도가 증진되고 장기강도가 매우 향상되는 것을 알 수 있었다. 또한 수축율이 저감되어 크랙을 방지할 수 있음을 알 수 있었다.As shown in the table, Examples 1 and 2 by using the paper ash and neutral activator alone or mixed with an alkali activator instead of cement, the curing speed is reduced compared to Comparative Example 1 to improve the initial strength and the long-term strength is very improved I could see. In addition, it was found that the shrinkage rate can be reduced to prevent cracking.
실시예 3과 실시예 4는 제지애시와 중성 활성화제에 알파형 반수석고를 첨가함으로써 비교예 1과 대비 시 강도와 내화성이 향상되는 것을 알 수 있었다. 또한 실시예 3은 경화속도가 매우 빠르나 이는 실시예 4처럼 지연제를 사용하여 작업시간을 충분히 확보할 수 있음을 알 수 있었다.In Examples 3 and 4, the addition of alpha-type hemihydrate gypsum to the papermaking ash and the neutral activator was found to improve the strength and fire resistance compared to Comparative Example 1. In addition, the curing rate of Example 3 is very fast, but it can be seen that the working time can be sufficiently secured by using a retardant as in Example 4.
실시예 5는 제지애시에 알칼리성 활성화제를 사용함으로써 비교예 2와 대비 시 지오폴리머 반응을 유도하여 강도와 내산성이 향상됨을 알 수 있었다.In Example 5, the use of an alkaline activator in papermaking induces a geopolymer reaction in comparison with Comparative Example 2, indicating that the strength and acid resistance are improved.
즉, 본 발명의 모르타르 조성물은 활성화제와 첨가제의 종류에 따라 경화시간, 내산성, 내화성 등의 성질을 조정하여 기존의 시멘트계 모르타르가 가지고 있는 단점을 보완할 수 있음을 알 수 있었다.In other words, it can be seen that the mortar composition of the present invention can compensate for the disadvantages of the conventional cement mortar by adjusting properties such as curing time, acid resistance, and fire resistance according to the type of the activator and the additive.
