收率減低試驗 的英文怎麼說
中文拼音 [shōulǜjiǎndīshìyàn]
收率減低試驗
英文
yield reduction test-
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。If stone ballast block blended with shrinkage - reducing agent, polypropylene fiber and expansion agent can reduce its own shrinkage while can ’ t worsen its own other properties, it is undoubted that modification of stone ballast block is beneficial to prevent crack in wall filled with stone ballast block, because these modification materials can respectively reduce, restrain and compensate shrinkage of concrete
在混凝土砌塊中摻加減縮劑、聚丙烯纖維和膨脹劑等減縮、限縮和補償收縮材料如能降低砌塊的收縮率，且不劣化砌塊的其它性能，則無疑有利於砌塊墻體的開裂防治。首先進行砌塊材料的改性試驗研究。
