摘要
摘 要:以环氧树脂乳液和普通硅酸盐水泥为原料,制备泡沫混凝土。研究了环氧树脂乳液对泡沫混凝土力学性能、吸水率、干密度和孔结构的影响。结果表明,掺入适量环氧树脂乳液可显著减小气孔的尺寸,优化孔径分布;泡沫混凝土的抗压和抗折强度随环氧树脂乳液的掺入得到显著的提高;环氧树脂乳液可以降低泡沫混凝土的吸水率,并在一定程度上减小了泡沫混凝土的干密度。
Abstract: The foamed concrete is prepared by using epoxy resin emulsion and ordinary portland cement as raw materials. The effect of epoxy resin emulsion on the mechanical properties, water absorption, dry density and pore structure of foamed concrete are studied. The results show that the size of the small hole can be reduced significantly and the pore size distribution can be optimized by incorporation of proper amount of epoxy resin emulsion. The compressive strength and flexural strength of foamed concrete are significantly improved with the incorporation of epoxy resin emulsion. The water absorption of the foamed concrete can be reduced by epoxy resin emulsion and the dry density of foamed concrete decreases to some extent.
