  1. 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

    通過對負溫混凝土早期防凍分析研究認為，環境溫度對混凝土的結構形成及其性能的影響十分突出，水泥水化溫升和環境散熱降溫兩個過程導致混凝土結構內部產生不均勻溫度場，對過渡相、水泥砂漿以及骨料都能產生不同程度的溫度損傷，產生內部溫差應力裂紋，初始損傷也是不可避免的。
