A Study on The Great Supplementary Value of Recycled Aggregates

재생 골재의 고부가가치화에 대한 연구

Until now, the quantity to recycle wasted concrete as the great supplementary value was very little. But considering a insufficiency of the present state of aggregates, the recycling of wasted aggregates is indispensable. This study will offer the basic application data of the recycled aggregates to make by the new attempt and offer the basic data of the great supplementary value of recycled aggregate to make good use of precast process. The result of compressive strength, tensile strength, flexural strength and drying shrinkage test of concrete by recycled aggregates were similar to the property of normal aggregate concrete, and the contrary effect of recycled aggregate by high temperature steam curing do not have been found out. Therefore the great supplementary value of recycled aggregate to make good use of precast process is possible way to be helpful to a insufficiency of the present state of aggregates.
