Abstract

In this paper, the manufactured sand was replaced by desert sand with contents to prepare desert sand concrete with different grades. Then the compressive strength, axial compressive strength, static compressive elastic modulus and axial tensile strength of desert sand concrete were tested to analyze the influence of desert sand replacement rate on the mechanical properties of concrete at different ages and different grades. It was shown that the negative influence of desert sand on the compressive strength of concrete would be increased with the increase of concrete grade, and the influence increased with the increase of age. The addition of sand would be resulted in the decrease of axial compressive strength and static elastic modulus of concrete, and with the increase of concrete grade, the strength would be decreased obviously. The addition of desert sand had no significant effect on the axial tensile strength of concrete in general.
