compressive modulus of elasticity meaning in Chinese

压缩弹性模量

Test results show that the steel fiber in concrete have more effectiveness on improving the splitting tensile strength and the flexural strength in the early age than after its hardening ; the flexural modulus of elasticity of sfrc are higher than the plain concrete at different ages while their compressive modulus of elasticity are almost the same . it ' s also shown that , similar to the plain concrete , the early - age loading decreases the strengths of sfrc , but , with the increase of the contents of the steel fiber things are getting better , especially for the splitting tensile strength and the flexural strength
试验结果表明：与性能稳定之后相比，在混凝土中掺入钢纤维对它的早期劈裂抗拉强度和抗折强度有尤为显著的提高作用；对各龄期的受压弹性模量影响不大，而对提高抗折弹性模量有一定的效果；与素混凝土试件相同，在早期(强度达到28天强度的85前)对钢纤维混凝土试件施加荷载会对它的各种强度产生一定的不利影响，但是掺入钢纤维可以减轻这种不利影响，尤其对劈裂抗拉强度和抗折强度作用突出，并且含纤率越高，效果越明显。
