Properties of the Concrete Bricks and Interlocking Blocks Made with the Industrial By-Product

산업부산물로 제조한 콘크리트 벽돌 및 인터록킹 블록의 특성

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.
