본 연구에서는 고로슬래그에 기반한 알카리활성 결합재를 이용한 벽돌, 호안용 블록 및 인터록킹 블록을 실험하여 친환경 무시멘트 콘크리트 2차 제품의 적용성을 평가하였다. 알카리활성화제의 종류와 양은 한국산업규격와 시방서의 콘크리트 2차 제품에 대한 요구성능에 따라 결정되었다. 실험결과 고로슬래그에 기반한 알카리활성 콘크리트 2차 제품은 한국산업규격과 시방서의 요구성능을 만족하였다. 특히, 고로슬래그에 기반한 알카리활성 결합재를 사용한 호안용 블록의 pH는 중성에 가까운 수준으로 어류의 식생에도 유리한 환경을 조성하였다. 고로슬래그 기반 알카리활성 결합재는 $CO_2$를 감소하는 친환경 콘크리트 2차 제품에 효과적으로 적용될 수 있다.

The present age, it has been often reported that recycling of wasted glasses should he a great topic in related business circles. For the enviromental reasons, a public institution are looking for the ways of recycling these waste glasses. First of all, the purpose of this research is to recycle crushed and powdered waste glasses by substituting for the cement in mortar and concrete. the optimum replacement ratio of Powdered Waste Glasses(PWG) can be obtained from the pilot test results. Secondary, we made advances in recycling of waste glasses as recycled to make secondary concrete products. so, we manufactured concrete brick, block and interlocking block for side walk contained powdered waste glasses. finally, we compare properties among of concrete products to slove the economical and environmental problems.

본 연구에서는 탈황석고(DG)에 이산화탄소를 반응시켜 제조한 탄산화물(CCMs)을 콘크리트 2차 제품의 시멘트 대체재로서 적용 가능성을 평가하고 최적 배합비 도출을 위한 탄산화물 혼입 모르타르 및 콘크리트 시편의 기초 물성 측정을 실시하였다. 탄산화물은 다량의 CaO 및 SO₃로 이루어져 있으며, 주요 결정상은 CaSO₄·2H₂O, Ca(OH)₂, CaCO₃ 및 CaSO₄로 나타났다. 또한 입도 분석 및 폐기물공정시험기준에 따른 중금속 측정 결과 콘크리트 2차 제품의 시멘트 대체재로서 탄산화물의 적용 가능성이 확인되었다. 모르타르 및 콘크리트 공시체 제작 후 강도 거동 측정 결과 탄산화물 혼입량이 증가할수록 강도가 감소하는 경향을 나타내었으나 최적 배합인 치환 비율 10 wt.% 배합까지 대상 제품인 인터로킹 블록 및 옹벽 블록의 기준에서 요구하는 모든 조건을 만족하였다. 따라서 콘크리트 2차 제품의 시멘트 대체재로서 적용 가능성이 확인되었다.

The propose of this study is to discover concrete secondary products for proper mixing by lightweight concrete. The standard of water ratio 50% and weight substition 0%, 10%, 20% by Fly-ash. When produce manufactures, there use for maintain its form weight substition and addition among the viscosity agent each Silica-fume and Hydroxy propyl methyl cellulos. Testing method was to operate slump, air content, compressive strength test, rapid freezing and thawing test. The result of this study is appeared when substition Fly-ash generally it had better use Silica-fume.

The presens study was aimed to investigate the possibility of use of pozzolanic materials such as blast furnace slag, fly ash, paper sludge ash which are produced from industrial wastes, as construction materials. Experiments were undertaken to investigate the properties of concrete bricks and interlocking blocks made with these industrial by-products. As a result, it was found that the concrete bricks and interlocking blocks made with substitute materials have equivalent strength and quality to those of conventional concrete bricks and interlocking blocks made with only cement. Thus, it could be expected that recycling the industrial wastes can reduce manufacturing costs of the cement as well as prevent environmental pollution by the use of the by-products thrown out as wastes to make secondary products of the concrete.

In this study, we confirmed the basic characteristics of paste and mortar 1:1, 1:2, 1:3 composition using concrete sludge solid content for the purpose of developing a resource-recycling cement secondary products. The 1:2 mortar formulation showed the best compressive strength. The steam curing strength is superior in the order of C20, BS40, BS20 and Control. it is judged that the FA combination is not suitable.

본 연구는 콘크리트 2차제품의 양생시간과 양생에너지원을 감소시키기 위한 방안으로써 조강형 시멘트 사용으로 거푸집 탈형이 가능한 콘크리트의 목표 강도를 15MPa로, 양생시간을 6시간으로 설정하여 콘크리트 2차제품의 조기강도 개선을 검토하였다. 실험결과, 목표 양생시간 6시간 내 탈형 강도 15MPa의 대기양생만으로 달성가능 했던 실험체는 ACC-100에서만 가능하였으며, TRC-100과 TRC-50 실험체의 경우 증기양생을 통한 6시간, 15MPa 값을 만족하였다. 그러나 ACC-100 실험체의 경우 초기 높은 급결성으로 인해 작업성 확보가 곤란하였으며, 작업성 개선을 위해서는 무수구연산 등의 지연제의 사용이 필요함을 알 수 있었다. 물-결합재비 변화에 따른 양상을 살펴보면 OPC-100, TRC-100, TRC-50의 경우 물-결합재비 저감에 따라 6시간내 목표 탈형 강도 달성은 증기양생의 경우 모두 만족하는 것으로 나타났으나, 대기양생의 경우 TRC-100, TRC-50은 12시간이내 15MPa 달성이 가능하였다.

The disadvantage of PMM's (polymer-modified mortars) that are currently on the market is the utilization of expensive polymer additives and also the cost of the other components. One of the possibilities how to decrease this price is the effective utilization of waste materials which are very inexpensive in spite of their good properties. The combinations of different degree in polymer adhesiveness and waste secondary raw materials - fly ash - are experimentally verified in the paper. The use of fly ash in adhesive materials for ceramic tiles is limited by unsatisfactory initial adhesiveness to sintered ceramic sherd as a result of a running pozzolanic reaction that lowers the efficiency of polymer additives. On the other hand, the use of adhesive and backfill coating materials for gluing ETICS board insulation materials has brought very good results.
