| Abstract: | By the basic mechanical property test of fly ash concrete,influences of the factors such as quantity of fly ash,water-cement ratio and age etc.on the compressive strength,the splitting tensile strength and the compressive modulus of elasticity of the hydraulic concrete were analyzed.The influence mechanism of fly ash on the mechanical property of the concrete was discussed.The test results indicated that with the increase of the quantity of fly ash,the early strength of the concrete reduced and its later strength was obviously increased. |
