摘要：
Modified rice husk ash (RHA) concrete was prepared by adding different RHA dosages at different ternperatures into cementitious composites. The durability of the binders was characterized using a freeze-thaw test, coupled with compressive strength and weight loss testing and a permeability resistance test. The microstructure of modified concrete was investigated by scanning electron microscopy (SEM). Because of freezing and thawing, the compressive strength and weight loss ratios of the modified concrete were decreased compared with the control concrete. The experimental data revealed that the...
