chemical restraint 中文意思是什麼
chemical restraint
解釋
化學約束-
The results of experiment on the relationship between tensile strength, shrinkage, self - desiccation shrinkage and flat restraint cracking show that sra ' s physical shrinkage - reducing effect and ea ' s chemical expansion effect greatly enhance the volume stability of concrete and reduce the probability of early - cracking
對減縮劑與膨脹劑抗拉強度、干縮、自乾燥收縮及平板約束開裂的試驗結果表明: sra的物理減縮作用及膨脹劑的化學膨脹作用,大大提高了混凝土早期的體積穩定性,降低了早期開裂的概率。
