摘要
介绍了碱矿渣胶凝材料高温后残余力学性能变化规律,包括抗压强度、抗拉强度和抗折强度,并讨论了碱浓度、模数、集料、掺合料等材料参数,养护条件及高温作业机制对高温力学性能的影响。并通过碱矿渣胶凝材料微观结构及产物的高温变化进一步解释了宏观力学性能的高温变化。
This paper reviews the changes in residual mechanical properties of alkali-activated slag cementitious materials after high temperature,including compressive strength,tensile strength and flexural strength,and discusses the effects of material parameters such as alkali concentration,modulus,aggregates and admixtures,curing conditions and high temperature operating mechanisms on these properties.The high temperature variation of macroscopic mechanical properties is also further explained by variations in microstructure and products of alkali-activated slag cementitious materials under high temperature conditions.
