【摘要】 通过对发泡剂原液结构、泡沫结构以及发泡剂泡沫与脱硫石膏、矿渣粉、水泥浆料相互搅拌混合过程的分析,发现发泡剂本身性质、最佳稀释倍数以及最合适的水胶比是决定泡沫混凝土泡沫稳定性的重要因素。本文研究了三种主流发泡剂泡沫与复合胶凝材料组成的二元体系的稳定性,试验结果表明:与废石膏复合胶凝材料最匹配的发泡剂是植物型发泡剂茶皂素,当其配制的浓度是1:200,水胶比为0.55时泡沫-复合胶凝材料二元体系稳定性最好。更多还原

【Abstract】 Through analyzing foaming agent concentrate composition,foam composition and the process of blending foam,desulfurization gypsum,ground granulated blast-furnace slag and Portland cement,it is discovered that the property of foaming agent,optimal dilution rate and optimal water cement ratio are crucial factors that affect the foam stability of foam concrete.The foam stability of three kinds of foaming agent when the foam is in the compound cementitious system was studied,The results show that:Tea saponin is best compatible with the compound cementitious material,and when its concentration is 1:200 and water cement ratio is 0.55,the stability of foam-compound cementitious system is the best.更多还原
