摘　　要：在钢纤维粉煤灰混凝土受压性能、受拉性能的研究基础上,进一步研究了钢纤维粉煤灰混凝土的抗折强度、轴心抗压强度、弹性模量以及钢纤维掺量和粉煤灰掺量与其力学性能的关系。研究结果表明:钢纤维粉煤灰混凝土强度随钢纤维体积率的增加,其抗折强度受影响较大,弹性模量和轴心抗压强度受影响也较明显。Based on the study on the behaviour of steel fiber reinforced fly ash concrete under compression propety, this paper deels with the following other mechanical propeties- bending strength, axial compressive strength , modulus of elasticity and the relationship of between volume ratio of steel fiber and flexural strength. Results of experimental study indicate ： the rational amounts of steel fiber and fly ash are ascertained. With the increase of volume ratio of steel fiber, bending strength is influenced more significantly, and so as elastic modulus.
