Tests were carried out to study the effects of the ratio of water to binder,the ratio and the over-weight coefficient of PFA displacing cement on the cubic compressed strength,the prismatic compressed strength,the elastic modulus,the splitting tensile strength and the axial tensile strength of manufactured sand concrete.It was suggested that the method of PFA over-weight displacing cement should be adopted for mixing manufactured sand PFA concrete.The rational value ranges of the ratio and the over-weight c...
