利用半定量XRD和SEM EDS分析、观察了补偿收缩水泥砂浆在模拟大体积混凝土内部温湿度条件下的水化产物相组成和微观形貌 .延迟钙矾石生成所导致的试件开裂是由于微晶状钙矾石在硬化砂浆中均匀膨胀所致 .
Using semi-quantitative XRD and SEM EDS analysis, the phase composition and the morphology of hydrated products of compensated shrinkage cement mortar under simulated temperature and humidity conditions were observed.The cracking of specimen caused by delayed ettringite formation was caused by the slight Crystalline ettringite in the uniform expansion of hardened mortar.
