With the increasing demand for aggregate 1 in engineering, the shortage of natural river sand resources and the environmental protection requirements of the project itself are constantly improving. It is an inevitable trend to replace some natural river sand to artificial sand. This experiment is used the control variable method to adjust the mixed ratio of artificial sand and river sand in concrete. Concrete of C30 strength grade is prepared in accordance with specifications with other mix ratios constant. After 28 days, it will be took out from the concrete curing room and carried on the compressive strength test. And we use the XRD of the crushed concrete block and the SEM of the microscopic electron microscope scanning to analyze the concrete and record the influence of the different mixed ratio on the compressive strength of concrete.

摘要

With the increasing demand for aggregate 1 in engineering, the shortage of natural river sand resources and the environmental protection requirements of the project itself are constantly improving. It is an inevitable trend to replace some natural river sand to artificial sand. This experiment is used the control variable method to adjust the mixed ratio of artificial sand and river sand in concrete. Concrete of C30 strength grade is prepared in accordance with specifications with other mix ratios constant. After 28 days, it will be took out from the concrete curing room and carried on the compressive strength test. And we use the XRD of the crushed concrete block and the SEM of the microscopic electron microscope scanning to analyze the concrete and record the influence of the different mixed ratio on the compressive strength of concrete.
