多孔混凝土性能及配合比设计方法研究

摘要

多孔混凝土是一种具有较大空隙率和较高强度的生态型混凝土,其配合比设计与普通混凝土不同。根据多孔混凝土结构特点和使用功能要求,提出了基于目标空隙率的体积法配合比设计方法,推荐了配合比参数的合理范围,并通过修筑试验路表明,该设计方法具有可行性。%Porous concrete is an eco-concrete with high porosity and high strength,its mix design is different from that of common concrete.According to the structure features and performance requirements of porous concrete,a mix design method,volume method based on target porosity is proposed.Moreover the rational ranges of mix parameters are also given.Finally,the construction of test road shows that this mix design method for porous concrete is feasible.
