粉煤灰与煤矸石混凝土压剪强度试验研究与分析
Research and Analysis on Compression Strength and Shear Strength Test of Fly Ash and Coal Gangue Concrete
摘要
Abstract
We study compressive strength and shear strength test of 28 d on concrete,10％ fly ash concrete,20％ fly ash concrete and coal gangue concrete;the experimental results show that the compressive strength of 10％ fly ash concrete,20％ fly ash concrete and coal gangue concrete compared with ordinary concrete has fallen by 45.25％,55.89％ and 17.11％;relations between shear strength and shear angle adopt linear fitting and exponential fitting for four different types of concrete;shear strength of ordinary concrete,10％ fly ash concrete and 20％ fly ash concrete changing with the shear angle conforms to exponential model,and shear strength of coal gangue concrete changing with the shear angle conforms to the linear model.关键词
