The important issues to be solved in the sidewalk block are to suppress the whitening phenomenon, to make it easy to manufacture, to maintain the strength to a necessary level, and the prior art which expresses "environment friendliness" It is not a sufficient alternative to urgent issues in the block. Particularly, in the prior art, since a high-priced natural material or the like is used, there is a disadvantage that the manufacturing cost of the sidewalk block is expensive, and it is not preferable from the viewpoint of waste of resources.
본 발명은 위와 같은 종래 기술의 한계를 극복하기 위하여 개발된 것으로서, 활용되지 못하고 폐기되던 산업부산물인 동 슬래그를 원료로 활용하여 높은 강도를 가지는 보도블록을 제작함으로써, 제작비용을 절감할 수 있으며, 더 나아가 백화현상 방지, 강도 증진, 및 제로슬럼프(zero slump) 조건에서의 워커빌러티(workability/작업성) 향상의 효과를 발휘하게 되는 보도블록과, 이를 제작할 수 있게 하는 조성물 및 제조방법을 제공하는 것을 목적으로 한다.The present invention has been developed in order to overcome the limitations of the prior art as described above, and it is possible to reduce the production cost by making the press block having high strength by using the copper slag, which is an industrial by- Furthermore, the present invention provides a sidewall block that exhibits the effect of preventing whitening, enhancing strength, and improving workability under zero slump conditions, and a composition and a manufacturing method for producing the sidewalk block .
위와 같은 과제를 달성하기 위하여 본 발명에서는, 친환경 고강도의 보도블록을 제작하기 위한 조성물로서, 조성물의 총 중량을 기준으로, 골재 75 내지 90중량%, 시멘트 10 내지 15중량%, 산업부산물로서 동 슬래그 1 내지 5중량%, 및 혼화제 1.5 내지 5.5중량%를 포함하여 구성되는 것을 특징으로 하는 보도블록 제작용 조성물이 제공된다.In order to achieve the above object, the present invention provides a composition for producing an environmentally friendly high strength press block, which comprises 75 to 90% by weight of an aggregate and 10 to 15% by weight of cement based on the total weight of the composition, 1 to 5% by weight, and 1.5 to 5.5% by weight of an admixture.
또한 본 발명에서는 상기한 조성물에 의해 제조된 보도블록과, 이러한 보도블록을 제조하는 방법이 제공된다.Also, in the present invention, a sidewall block manufactured by the above composition and a method of manufacturing such sidewalk block are provided.

본 발명에 의하면, 자원으로 활용되지 못하고 폐기되던 "동 슬래그"를 보도블록의 재료로 활용함으로써, 강도 증진, 제로슬럼프(zero slump) 조건에서의 워커빌러티(workability/작업성) 향상 등을 효과를 발휘하게 된다. According to the present invention, "copper slag", which has not been utilized as a resource but has been discarded, is used as a material of a sidewalk block, thereby enhancing strength and improving workability in zero slump conditions. .
특히, 본 발명에서는 폐기되던 산업부산물인 "동 슬래그"를 재활용하게 되므로, 산업부산물을 폐기하는데 소요되는 비용을 절감할 수 있게 된다. Particularly, in the present invention, "copper slag", which is a by-product of industrial waste, is recycled, so that the cost for disposing industrial by-products can be reduced.
이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다. 본 발명은 도면에 도시된 실시예를 참고로 설명되었으나 이는 하나의 실시예로서 설명되는 것이며, 이것에 의해 본 발명의 기술적 사상과 그 핵심 구성 및 작용이 제한되지 않는다. 참고로 본 명세서에서 "보도블록"은 보행자가 다니는 보도에 포설되는 블록만을 의미하는 것이 아니라, 차량이 통행하는 차도에 포설되는 블록도 포함하는 의미로 이해되어야 한다. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby. For the sake of reference, the term "sidewalk block" in the present specification should be understood to mean not only a block installed on the sidewalk on which the pedestrian runs, but also a block installed on the roadway on which the vehicle is traveling.
본 발명에 따른 친환경 고강도의 보도블록을 제작하기 위한 조성물은, 조성물의 총 중량을 기준으로, 골재 75 내지 90중량%, 시멘트 10 내지 15중량%, 산업부산물로서 동(銅) 슬래그 1 내지 5중량%, 및 혼화제 1.5 내지 5.5중량%를 포함하여 구성된다. The composition for producing an eco-friendly high strength press block according to the present invention comprises 75 to 90% by weight of aggregate, 10 to 15% by weight of cement, 1 to 5% by weight of copper slag as industrial by- %, And 1.5 to 5.5 wt% of an admixture.
"동(銅) 슬래그"은 산업부산물로서 발생하는 것인데 종전에는 자원으로 활용되지 못하고, 추가 비용을 들여서 폐기하여야만 했다. 본 발명에서는 이러한 동 슬래그를 재료로 활용함으로써, 비용 절감과 자원재활용에 의한 친환경성을 높이면서도, 본 발명의 조성물로 제작되는 보도블록이 고강도를 발휘하도록 한다. "Copper slag" occurs as an industrial by-product, but it has not been utilized as a resource in the past and had to be disposed of at an additional cost. In the present invention, by using such copper slag as a material, the sidewall block made of the composition of the present invention exhibits high strength while enhancing the cost-saving and environment-friendliness due to recycling of resources.
구체적으로 본 발명에서 동 슬래그는 전체 조성물의 총 중량을 100중량%라고 하였을 때 1 내지 5중량%로 함유된다. 동 슬래그의 함유량이 1중량% 미만일 경우, 산업 부산물의 재활용이라는 친환경적인 효과가 미미하다. 특히, 동 슬래그가 1중량% 미만으로 함유되는 경우 보도블록의 표층에 동 슬래그 함유에 의한 심미감 향상의 효과가 미미하다. 반면에 동 슬래그의 함유량이 5중량%를 초과하는 경우에는, 보도블록의 표층에 동 슬래그 함유로 인한 심미감의 변화가 너무 과도해져서, 오히려 심미감의 저하가 유발되므로, 동 슬래그의 함유량은 1 내지 5중량%이 되어야 한다. Specifically, the copper slag in the present invention is contained in an amount of 1 to 5% by weight based on 100% by weight of the total composition. If the content of the copper slag is less than 1% by weight, the environment-friendly effect of recycling industrial by-products is insignificant. Particularly, when the copper slag is contained in an amount of less than 1% by weight, the surface layer of the sidewalk block is insignificant in improving the sense of beauty due to the inclusion of copper slag. On the other hand, when the content of the copper slag is more than 5% by weight, the change of the aesthetics due to the inclusion of the copper slag is excessively excessive in the surface layer of the sidewalk block, resulting in deterioration of the aesthetics. To 5% by weight.
특히, 본 발명에서 사용되는 동 슬래그는, 그 입경이 0.1 내지 5mm의 크기를 가지는 것이다. 동 슬래그의 입경이 0.1mm 미만이면, 동 슬래그 입자가 지나치게 작아져서 동 슬래그 함유에 의한 보도블록의 심미감 향상 효과가 저하되며, 반대로 입경이 5mm를 초과하면 동 슬래그 입자가 너무 커져서 보도블록의 표면에 마치 점이 박혀 있는 듯한 외관을 보이게 되어 오히려 심미감이 저하되는 문제가 있다. 따라서 본 발명에서 동 슬래그는 그 입경이 0.1 내지 5mm의 범위 내에 있는 것을 사용한다.Particularly, the copper slag used in the present invention has a particle size of 0.1 to 5 mm. If the particle diameter of the copper slag is less than 0.1 mm, the copper slag particles become too small and the effect of improving the feel of the pressed block due to the copper slag is deteriorated. On the contrary, if the particle diameter exceeds 5 mm, the copper slag particles become too large, The appearance of a point as if the point is embedded is displayed, and the aesthetic sense is deteriorated. Therefore, in the present invention, the copper slag has a particle diameter in the range of 0.1 to 5 mm.
본 발명에 따른 조성물에서, 혼화제는 전체 조성물의 총 중량을 100중량%라고 하였을 때 1.5 내지 5.5중량%로 포함되는데, 폴리아크릴레이트(Polyacrylate), 아크릭 폴리머 에멀젼(Acrylic Polymer Emulsion), 및 설포네이티드 폴리스티렌(Sulfurnated Polystyrene)으로 이루어진 군에서 선택된 하나 이상의 재료로 이루어질 수 있다. 혼화제를 위와 같은 조성범위로 함유함으로써, 본 발명에 따른 조성물로 보도블록을 제작하였을 때, 보도블록의 초기 강도가 혼화제를 사용하지 않은 경우에 비하여 약 10 내지 20% 증진되는 효과가 발휘된다.In the composition according to the present invention, the admixture includes 1.5 to 5.5% by weight, assuming that the total weight of the entire composition is 100% by weight. Examples of the admixture include polyacrylate, Acrylic Polymer Emulsion, And at least one material selected from the group consisting of polystyrene (Sulfurnated Polystyrene). By containing the admixture in the composition range as described above, when the sidewall block is made of the composition according to the present invention, the initial strength of the sidewalk block is enhanced by about 10 to 20% as compared with the case where the admixture is not used.
혼화제의 함유량이 1.5중량% 미만일 경우, 보도블록의 초기 강도 증진 효과가 미미하며, 반대로 5중량%를 초과할 경우에는 강도증진 효과의 향상은 작은데 비하여 혼화제 사용에 따른 비용 증가가 커지게 된다. 따라서 본 발명에서 혼화제의 함유량은 1.5 내지 5.5중량%로 한다.When the content of the admixture is less than 1.5% by weight, the effect of improving the initial strength of the sidewalk block is insignificant. On the contrary, when the content of the admixture exceeds 5% by weight, the increase in the strength enhancement effect is small. Therefore, the content of the admixture in the present invention is 1.5 to 5.5 wt%.
아래의 표 1에는 위에서 제시한 각각의 혼화제를 사용하였을 때 60T 두께의 보도블록에 대해 KS F 4419 규정에 따라 휨강도 시험을 수행한 결과가 정리되어 있다. 구체적으로 아래의 표 1의 실험예는, 조성물 총 중량을 기준으로 골재 80중량%, 시멘트 15중량%, 동 슬래그 2.5중량% 및 혼화제 2.5중량%를 포함하는 것에 대한 것이며, 이 때 동 슬래그의 입경은 2mm이었다.Table 1 below shows the results of the bending strength test according to KS F 4419 for 60-story thick sidewall blocks with each of the admixtures listed above. Specifically, the experimental examples given in Table 1 below are for the inclusion of 80 wt% of aggregate, 15 wt% of cement, 2.5 wt% of copper slag and 2.5 wt% of admixture based on the total weight of the composition, Was 2 mm.
위의 표 1에서 확인되는 바와 같이, 본 발명에 따른 조성물은, 위에서 제시한 혼화제를 포함함으로써, 제로슬럼프(zero slump) 조건 하에서도 우수한 워커빌리티를 가지게 될 뿐만 아니라, 필요한 충분한 휨강도를 가질 수 있게 되는 바, 강도증진 효과를 확인할 수 있다. 특히, 본 발명에서는 상기한 혼화제의 함유에 의해, 보도블록의 초기 강도 증진 효과를 기대할 수 있으며, 혼화제 사용량만큼 시멘트의 사용량을 줄일 수 있게 되어, 경제성 향상의 효과도 기대할 수 있다.As shown in Table 1 above, the composition according to the present invention not only has excellent workability even under zero slump conditions, but also has sufficient bending strength necessary Bar, strength enhancement effect can be confirmed. Particularly, in the present invention, the effect of improving the initial strength of the sidewalk block can be expected by the inclusion of the admixture described above, and the amount of cement used can be reduced by the amount of the admixture used, thereby improving the economical efficiency.
본 발명에 따른 조성물에서, 골재는 전체 조성물의 총 중량을 100중량%라고 하였을 때 75 내지 90중량%로 포함되는데, 골재의 천채 함유량을 100중량부라고 하였을 때, 본 발명에서 사용되는 골재 중, 천연골재가 아닌 기존 콘크리트 부재 등에서 재활용되도록 만들어진 순환골재는 40 내지 60중량부로 포함된다. 이와 같은 량으로 순환골재를 사용함으로써, 친환경성을 더욱 강화시킬 수 있을 뿐만 아니라, 제조비용도 크게 절감할 수 있게 되는 효과가 발휘된다.In the composition according to the present invention, the aggregate contains 75 to 90% by weight based on 100% by weight of the total composition. When the aggregate content of the aggregate is 100% by weight, The recycled aggregate which is made to be recycled in a conventional concrete member or the like other than natural aggregate is included in 40 to 60 parts by weight. By using the recycled aggregate in such an amount, the eco-friendliness can be further enhanced, and the manufacturing cost can be greatly reduced.
