通过改变原材料中氧化物摩尔比,采用混凝土快冻法,探索地聚合物混凝土n(SiO2)/n(Al2O3)、n(Na2O)/n(Al2O3)及n(H2O)/n(Na2O)摩尔比在不同取值范围内的抗冻规律,并与普通硅酸盐混凝土进行对比。试验结果表明:在研究的氧化物组成取值范围内,地聚合物混凝土质量损失与相对动弹性模量均小于普通硅酸盐混凝土,表现出很好的抗冻性能。
By changing the mole ratio of oxides in the raw materials and adopting the concrete quick-freezing method, the effects of mole ratio of n (SiO2) / n (Al2O3), n (Na2O) / n (Al2O3) and n (H2O) / n Compared with the antifreeze law in different value range, and compared with ordinary Portland concrete. The experimental results show that the mass loss and relative dynamic elastic modulus of geopolymer are both less than that of ordinary Portland cement in the range of oxide composition, which shows good frost resistance.
