碱激发矿渣-赤泥新型低碳透水混凝土性能研究
Study on Properties of New Low-Carbon Pervious Concrete with Alkali-Activated Slag-Red Mud
摘要
Abstract
Pervious concrete was prepared with two industrial solid wastes of granulated blast-furnace slag and Bayer red mud as cementitious materials,sodium silicate solution as alkali activator,and limestone gravel as coarse aggregate.The effects of design porosity,water-binder ratio and aggregate size on the strength and permeability of pervious concrete were studied respectively.The optimal water-binder ratio is in-fluenced by the design porosity and aggregate size.When the design porosity of pervious concrete is 15%and the aggregate size is 4.75-9.50 mm,the optimal water-binder ratio of 0.36 and it has a higher strength and has good water permeability.The mechanics and permeability per-formance of alkali-activated slag-red mud pervious concrete are better than those of cement pervious concrete,which is in line with the devel-opment concept of low carbon and green.关键词
