폐유리 파쇄골재와 고로슬래그 시멘트를 이용한 보차도용 콘크리트 인터로킹블록 및 투수콘크리트 인터로킹블록의 제조방법{Manufacturing Methods of Concrete Interlocking Block and Permeable Concrete Interlocking Block for Roadway and Sidewalk Using Crushed Aggregates from Waste Glasses and Blast Furnace Cement.}Manufacturing methods of concrete interlocking block and permeable concrete interlocking block for roadway and sidewalk using crushed aggregates from waste glasses and blast furnace Cement.}

본 발명은 폐유리 파쇄골재를 이용하여 보차도용 콘크리트 인터로킹블록과 투수콘크리트 인터로킹블록을 제조하기 위한 것으로써 폐유리 파쇄골재의 혼입률, 최대치수, 입도범위 등을 최적으로 결정하여 제품의 역학적성능과 내구성능이 우수하고 미관이 좋은 고성능, 고인성의 보차도용 콘크리트 인터로킹블록과 투수콘크리트 인터로킹블록을 제조하는 방법에 관한 것이다.The present invention is to manufacture the concrete interlocking block and permeable concrete interlocking block for sidewalks using waste glass crushed aggregates to determine the mixing ratio, the maximum dimension, the particle size range of the waste glass crushed aggregates optimally, and the mechanical performance of the product. The present invention relates to a method for manufacturing a high performance, high toughness concrete interlocking block and permeable concrete interlocking block having excellent durability and good aesthetics.

생활폐기물로 배출되는 폐유리의 약 50％ 정도만이 재활용되고 있으며 건설용 대체재료로서의 재활용은 거의 없는 실정이다. 또한 건설폐기물로 발생되는 폐유리는 혼합폐기물로 발생되어 분리 수거만 가능하면 재활용이 가능하지만 이의 재활용은 거의 이루어지지 못하고 있다.Only about 50% of the waste glass discharged as household waste is recycled, and there is little recycling as an alternative material for construction. In addition, waste glass generated as construction waste is generated as mixed waste and can be recycled only if it can be collected separately, but its recycling is hardly achieved.

종래의 폐유리를 이용한 보도블록의 제조방법에 있어서는 폐유리 분말과 시멘트를 일정한 비율로 혼합하여 제조하는 방법이 제안되어 있지만 이것은 폐유리 파쇄분말의 혼입에 따라 발생하는 알칼리골재반응을 고려하지 않은 것으로 알칼리 골재반응의 진행에 의한 제품의 균열에 겔의 석출, 팽창 변형등의 성능저하를 초래할 수 있다.In the conventional manufacturing method of the sidewalk block using waste glass, a method of mixing waste glass powder and cement at a predetermined ratio has been proposed, but this does not take into account the alkali aggregate reaction caused by the mixing of waste glass crushed powder. Degradation of the product due to the progress of the alkaline aggregate reaction may cause degradation of the gel, swelling and deformation.

또한 텔레비젼 브라운관 제조시 발생하는 연마세척오니를 건조시켜 파쇄한 폐유리 골재를 사용하여 보도블럭을 제조하는 경우에도 역시 알카리골재반응에 의한 성능저하의 우려가 있으며 폐유리의 재활용 측면에서도 대상으로 하는 폐유리가 국한되어 있고 그 유효이용량이 많지 않다는 단점이 있다.In addition, the production of sidewalk blocks using waste glass aggregates that have been dried and crushed by the cleaning of sludge produced in television CRT can also cause performance degradation due to alkali aggregate reactions. The disadvantage is that glass is limited and its effective capacity is not high.

따라서 본 발명에서는 생활폐기물로 배출되는 폐유리를 파쇄하여 골재로 사용함으로써 대량의 폐유리 재활용이 가능하고 고로슬래그시멘트를 사용하고 폴리머분산제(SBR Latex 또는 EVA Latex)를 혼입함으로써 폐유리 파쇄골재의 혼입에 의한 알카리 골재반응을 억제할뿐아니라 보강용섬유(매쉬형 폴리프로필렌단섬유 또는 내알카리성 유리단섬유)를 혼입하여 성능을 개선시킨 우수한 품질의 보차도용 콘크리트 인터로킹블록과 투수콘크리트 인터로킹블록의 제조가 가능하다.Therefore, in the present invention, it is possible to recycle a large amount of waste glass by crushing the waste glass discharged as household waste, and to use the blast furnace slag cement and mix the polymer dispersant (SBR Latex or EVA Latex) to mix the waste glass crushed aggregate. In addition to suppressing the alkaline aggregate reaction by the reinforcement, the reinforcing fiber (mesh type polypropylene short fiber or alkali resistant glass short fiber) is mixed to improve the performance of high quality concrete interlocking block and permeable concrete interlocking block. Manufacturing is possible.

본 발명은 이와 같이 보차도용 콘크리트 인터로킹블록과 투수콘크리트 인터로킹블록을 제조할 때 폐유리를 파쇄하여 골재로 사용하는 경우의 발생하는 문제점을 해결함과 동시에 우수한 역학적성질과 내구성능 등의 품질성능을 갖춘 제품을 제조하기 위하여 고로슬래그시멘트와 폴리머분산제 (SBR Latex 또는 EVA Latex) 및 보강용섬유(매쉬형 폴리프로필렌단섬유 또는 내알카리성 유리단섬유)를 사용하는 것으로서 대량의 폐유리 재활용이 가능하게 함과 동시에 고강도, 고인성, 고내구성 등의 성능이 우수한 보차도용 콘크리트 인터로킹블록과 투수콘크리트 인터로킹블록을 제조가 가능하도록 한 것에 그 목적이 있다.The present invention solves the problems caused when the waste glass is broken and used as aggregate when manufacturing the concrete interlocking block and the permeable concrete interlocking block for the roadway, and at the same time, the quality performance, such as excellent mechanical properties and durability performance Blast furnace slag cement and polymer dispersant (SBR Latex or EVA Latex) and reinforcing fiber (mesh type polypropylene short fiber or alkali resistant glass short fiber) are used to manufacture products with high efficiency. At the same time, the purpose of the present invention is to enable the manufacture of concrete interlocking blocks and permeable concrete interlocking blocks having excellent performance such as high strength, high toughness, and high durability.
