建筑固废机制砖混再生骨料混凝土抗压强度试验研究
Experimental Study for Compressive Strength of Machine-Made Recycled Aggregate Concrete Deriving From Brick and Mixed Construction Waste
摘要
Abstract
In order to solve the problem of huge amount of brick-concrete waste construction waste polluting the environment and wasting resources in the process of urbanization in China,the natural aggregate was replaced by mechanical recycled brick-concrete aggregate,which aimed to analyze the feasibility of brick-concrete recycled aggregate as recycled concrete aggregate through experiments,and study the influence of brick-concrete recycled aggregate with different replacement mass fractions on the compressive strength of recycled concrete.The results showed that the reduction rate of compressive strength of concrete cube added with brick-concrete recycled aggregate increased with the increase of the replacement rate of recycled aggregate.When the replacement rate of recycled brick aggregate was within 10%,it had basically no effect on the strength,and when the proportion of brick-concrete aggregate exceeded 25%,the strength of brick-concrete aggregate recycled concrete began to decay significantly.关键词
