Abstract
In order to study the performance of self-compacting rubber concrete,the rubber powder was replaced by different proportion of coarse aggregate and fine aggregate to make specimens.The effects of different substitution amount and water reducing agent content on the working and mechanical properties of self-compacting rubber concrete were studied.The results show that with the increase of rubber powder substitution,slump flow diameter first stabilizes and then decreases,slump flow time increases,J-ring height difference first decreases and then increases,and compressive strength decreases.The higher the amount of superplasticizer,the larger the flow diameter and the lower the flow time.In summary,the optimal replacement amount of rubber powder is 20%.关键词
