Experimental on Mechanical Properties of Mixed Sand Concrete

摘要

Natural sand is becoming increasingly scarce, manufactured sand is always with unsatisfactory grading. In this paper, the natural sand concrete and the manufactured sand concrete were prepared to the mixed sand concrete. The mechanical properties of natural sand concrete, manufactured sand concrete and mixed sand concrete are studied in this paper. Test results showed that: mixed sand concrete composed of manufactured sand concrete and natural sand concrete with appropriate proportion has good working performance and mechanical properties, which may meet the technical requirements of concrete.
