摘要

本文对可持续建筑材料——耐高温碱活性砂浆进行了研究。一种无水泥碱活性粘结剂[地聚合物]，以煤燃烧产生的碱活性粉煤灰为基础，使用珍珠岩、珍珠岩粉尘和微球作为填料。分析的目的是研究填料对无水泥砂浆导热系数、抗压强度和微观结构的影响。结果表明，珍珠岩砂的添加量为30%，效果最佳。其他测试的轻质填料没有显著改变测试砂浆的导热性。

Air entrance additive effect on geopolymer mortar thermal conductivity

The article deals with research on sustainable building materials - alkali-activated mortars with high temperature resistance. A cement-free alkali-activated binder [geopolymer] based on alkali-activated fly ash from coal combustion using perlite, perlite dust and cenospheres as filler. The object of the analysis was to study the effect of fillers on the coefficient of thermal conductivity, compressive strength and microstructure of the cementless mortars. The results showed that the most effective addition was perlite sand in the amount of 30%. The other tested lightweight fillers did not significantly change the thermal conductivity of the tested mortars.
