Examples
- The compatibility and harmony among workability , mechanical grade and durability are optimized , with the ground of adjusting composition and dosage of fd - 1 ; after analyzing anti - freezing damage mechanism , it is concluded that temperature is main factor , which affects structure and property of concrete . after two processes of temperature - elevation of hydration heat and temperature - descent of cold - environment , there is original damage in concrete and its existence leads to temperature fields , as results in temperature damage on transition phase > aggregate and cement mortar of concrete
通过对负温混凝土早期防冻分析研究认为，环境温度对混凝土的结构形成及其性能的影响十分突出，水泥水化温升和环境散热降温两个过程导致混凝土结构内部产生不均匀温度场，对过渡相、水泥砂浆以及骨料都能产生不同程度的温度损伤，产生内部温差应力裂纹，初始损伤也是不可避免的。
