摘要
该文分别研究了粉煤灰、矿渣粉和两者混和物对混凝土抗裂性的影响,共做了7组试块。研究结果表明:适量优质粉煤灰或适量矿渣粉或双掺掺合料的掺加有利于减缓混凝土早期干缩开裂现象的发生;但若继续增加,则对提高混凝土早期抗裂性不利。
The impact of fly ash,slag powder and the mixture of the two materials on crack resistance of concrete is studied in the paper through seven groups of experiments on concrete samples.The results show that proper amount of high quality fly ash,slag powder or mixture can improve the crack resistance of concrete,but reduce crack resistance if the amount is excessive.
