地质聚合物是以无机Si-Al质材料与高碱溶液反应制得一种具有优异性能的新型胶凝材料。本文制备了不同模数的水玻璃，研究了水玻璃模数及掺量对粉煤灰-矿渣系统的激发效果，探讨了高温养护对其力学性能的影响。结果表明，满足成型要求的前提下，模数为1.4的水玻璃最佳掺量为25%；高温养护对于系统的强度有较大提高。
Geopolymer is a new type of binding materials with good performance composed of inorganic silicon aluminum materials and alkaline solution. Water glass solutions were made with different modulus and solid content,and the alkali-activated effect on fly ash-slag system were investigated. The influence of high temperature on mechanical property was studied. The results show water glass with modulus of 1. 4 and solid content of 25% is optimal and high temperature curing contributes to mechanical property improvement.
