STUDY ON AN APPLICATION FOR CONCRETE USING RECYCLED COARSE AGGREGATE CLASS M TO BUILDING FLAME

The purpose of this study is to apply concrete using recycled coarse aggregate class M to building flame affected by drying shrinkage. Therefore concrete using recycled coarse aggregate class H and M are compared durability. In addition, quality control of recycled coarse aggregate for practical use is examined. As the result, it is confirmed that the durability of recycled coarse aggregate concrete is no relationship with the quality of recycled coarse aggregate. In addition, it is confirmed that early stage judgment method of drying shrinkage is applicable to the quality control.
