玄武岩纤维高性能混凝土早期抗裂性能试验研究
Experimental study on early cracking behaviors of basalt fiber reinforced high performance concrete
摘要
Abstract
Using improved plate method for the amount of fly ash and basalt fiber content of early experiment study on crack resistance of high performance content.First of all,test by single mixing fly ash,it is concluded that the optimal dosage of fly ash is 30％,then the different dosage of basalt fiber mixed into as the benchmark of 30％ dosage of fly ash in concrete,getting the optimal value of basalt fiber content.Results show that basalt fiber mixed with little effect on slump of concrete,but the early cracking area of high performance,initial cracking time plays a significant role in improving.When the dosage of fly ash in 30％,basalt fiber content is 1.6 kg · m-3,the high-performance concrete early cracking the smallest area,improve the best effect.关键词
