摘要
研究了不同龄期和不同性能PVA纤维对SHCC抗压性能的影响,获得了SHCC材料的压应力-应变全曲线及不同试件的抗压性能规律.结果表明:随着龄期的增长,SHCC抗压强度提高,变形性能有所下降;掺加纤维2制作的试件变形性能低于纤维1制作的试件,但强度相差不大.研究成果可为此种材料在工程结构中的研究与应用提供理论依据.
The influence of different fiber type on compressive performance of SHCC was researched and the compressive stress-strain full curves and performance rule of different specimens was obtained. The results show that deformation per- formance of SHCC reduced and compressive strength increased along with the growth of the ages; the deformation per- formance of SHCC with fiber 2 is lower than that of SHCC with fiber 1, but their strength was not significantly different. The experimantal and analytical conclusion can provide a lot of theoretical bases for the research on the performances of SHCC.
