초록
The purpose of this study is to attempt to use broken red brick, which is categorized as impurities of circular aggregate to thick aggregate, as a replacement for concrete. Through the material test and performance test for each mixing rate of the broken red brick (0%, 30%, 60%), the following conclusion was reached by studying the material and structural characteristics of circular aggregate to the concrete. Even though broken red brick, which is categorized as impurities of circular aggregate, is mixed 30% with normal rubble, the compression strength, intensity strength, and curving strength was similar to that of concrete that uses normal rubble. Therefore, concrete beam made with broken red brick can be applied to the real construction field. Also, the study regarding the cutting test of the concrete that uses broken red brick and regarding applying and mixing admixture that can increase the ductility factor will be required in the future.
