Uniaxial Compressive Mechanical Performance of Basalt Fiber Fabric-Steel-PVA Engineered Cementitious Composites
摘要
Abstract
The combined effect of basalt fiber fabric and hybrid short-cut fibers(steel fiber and PVA fiber,short-cut fibers overall volume fraction of 2%)on uniaxial compressive mechanical performance of basalt fiber fabric-steel-PVA engineered cementitious composites(BTR-HyECC)was investigated.Various compressive performance indicators of specimens were obtained through cylindrical uniaxial compressive tests,and stress-strain curves were plotted.The results indicate that,with a 0%(volume fraction,the same below)steel fiber content,the introduction of basalt fiber fabric significantly enhances compressive strength,peak strain,and compressive toughness of specimens.As the steel fiber content increases to 1%,compressive strength and elastic modulus of specimens reach maximum values,and when the steel fiber content is 1.5%,the deformability and compressive toughness of specimens reach optimum levels.Based on the experimental data,a uniaxial compressive stress-strain constitutive equation suitable for BTR-HyECC was established,which agree well with the experimental results.关键词
