On early mechanical properties of artificial sand concrete

En recent years, large-scale infrastructural projects, in order to protect the River, there was a growing shortage of natural river sand resources, contradictions between supply and demand in areas of scarcity of natural resources are more prominent. Therefore, for high quality natural resources exploitation and utilization of artificial sand is an important and urgent issue. Concrete with artificial sand has received an increasing number of applications in engineering, artificial sand for sand has been classified as building by GB/T14684-2001 ([1]) Technical code for construction of highway bridges and culverts, JTJ041-2000([2]), provides when you are difficult to get natural river sand, artificial sand processing of hard rock can also be used. This article mainly studied the early performance of mechanical properties of concrete with artificial sand, to support early-strength concrete provides the application of theory.
