尾矿砂混凝土板的力学性能试验研究

摘要

为研究尾矿砂应用于混凝土楼板中的可能性，设计了5块不同替代率（0、40%、50%、60%、70%）的混凝土单向板对比试验，研究了尾矿砂替代率对混凝土单向板力学性能的影响规律，为尾矿砂混凝土的推广利用提供了试验依据。%In order to study the possibility of application of tail sand in concrete floor, an experiment which contains five one-way slabs with different replacement rate (0, 40%, 50%, 60% and 70%) is designed and carried out. And the influence of replacement rate of tail sand on cracking load, ultimate load, the maximum width of crack and the mid-span deflection of one-way concrete slabs are studied, which can provided experimental evidences for the popularization and utilization of tail sand concrete .
