本文研究了不同掺量粉煤灰砂浆的水化温升和断裂性能参数的变化趋势。并在此基础上 ,运用线弹性断裂力学理论 ,提出混凝土温度应力及其相应抗裂能力之间关系的理论分析思路。且以简化形式实现了数学计算
In this paper, the variation trends of hydration temperature rise and fracture properties of fly ash mortar with different dosages were studied. On this basis, the theory of linear elastic fracture mechanics is put forward, and the theoretical analysis of the relationship between temperature stress and its corresponding cracking resistance is put forward. And to achieve a simplified form of mathematical calculations
