干燥与潮湿环境下混凝土抗压强度和弹性模量发展分析
Development of strength and elastic modulus of concrete under moisture and drying curing conditions
摘要
Abstract
The compressive strength and elastic modulus of C30, C50 and C80 concretes cured in moisture and drying environments respectively at typical ages were measured to investigate the effect of curing conditions. The results show that drying conditions reduce the concrete＇s compressive strength and elastic modulus. The development history of strength and elastic modulus was modeled by both maturity method and hydration degree concept. A modified method based on hydration concept was proposed to predict the effect of interior moisture content on the strength and the elastic modulus of concrete. The model predictions on strength and elastic modulus of concrete under different curing conditions agree well with experimental resuits. In addition, two models describing the relationship between compressive concrete strength and elastic modulus were analyzed with obtained experimental data, which indicates that it is not reasonable to calculate modulus of normal and high performance of concrete with strenzth values bv fixed 13arameter models.关键词
