矿物掺合料对高性能混凝土塑性收缩裂缝的影响
Experiment of mineral blenders on high performance concrete plastic shrinkage crack
摘要
Abstract
In order to study the influence of the content of fly ash,slag and silica fume on the early-age plastic shrinkage crack of the high performance concrete,this paper adopted the constraints in the plate method.Mean-while,the early-age plastic shrinkage crack mechanism of concrete was analyzed.The results show that the in-corporation of fly ash and slag on the early-age concrete plastic cracking are good inhibitory effect,and fly ash is superior to the inhibitory effect of slag.Silica fume could increase the early-age plastic cracking of concrete, and with the increase of dosage,cracking is becoming ever more obvious.关键词
