摘要 地质聚合物混凝土力学性质优于普通的水泥混凝土。通过坍落度试验、抗压试验、抗拉试验和收缩试验探究碱用量、矿渣用量与固化时间对地质聚合物混凝土力学性质的影响,结果显示在一定范围内,增加碱用量会导致地质聚合物混凝土的坍落度、抗压抗拉强度和干收缩率增加;而增加矿渣用量会导致坍落度减小,抗压抗拉强度和干收缩率增加。 This article introduces the concept of geopolymer concrete. Through the experimental method, the mechanical properties of geopolymer concrete were verified that are better than common concrete. From the results of workability slump test, compression test, splitting tensile test and drying shrinkage test, the influence of alkali dosage, ground granulated blastfurnace slag and curing duration to the mechanical properties of geopolymer concrete were developed. In the certain range, increasing the dosage of alkali would increase the slump, compression strength, tensile strength and drying shrinkage; the increment of alkali dosage would cause the increase of compression strength, tensile strength and drying shrinkage while the decrease of slump.
