再生骨料替代率对混凝土性能影响的实验分析

摘要

Recycled concrete is made from different recycled aggregates replacement rate.Comparing recycled concrete with ordinary concrete from workability,elastic modulus and compressive strength,the article analyzes the impact on the concrete properties from the changes of recycled aggregates substitution rate.The experiment proved that the recycled concrete is equal to ordinary concrete,which is compounded by appropriate recycled aggregates replacement rate.With the emphasis on environmental protection,the development of recycled concrete will be more valuable in application.%用不同的再生骨料替代率,制成再生混凝土。从再生混凝土的和易性、弹性模量和抗压强度等三个方面与普通混凝土进行比较,分析再生骨料替代率的变化对混凝土性能的影响。试验证明,采用适当的再生骨料替代率配制的再生混凝土与普通混凝土基本相当。随着人类对环保的日益重视,再生混凝土产业的发展空间很大,对混凝土的工程应用具有一定的价值意义。
