尾矿人工砂高性能混凝土研究

Study on High Performance Concrete with Tail Mineral Sand

系统的研究了尾矿人工砂的技术路线、配合比、机械性能和高强混凝土的氯离子渗透试验。检验了坍落度、流动性、综合强度和氯离子扩散作用。在试验基础上,讨论了相关的机械设备。结果表明,尾矿以及尾矿人工砂可以用于拌合高性能混凝土。

In this paper,the technical channel,match ratio,mechanical property,and anti-chlorine permeability of HPC with tail mineral sand are studied systematically.Slump,slump flow,comprehensive strength and chlorine diffusion are tested.On the basis of these tests,the correlative mechanisms are discussed.The result shows that HPC can be compounded with tail mineral sand or the mixture of tail mineral sand and manufactured sand.
