On early Mechanical Properties of Artificial Sand Concrete

This paper studies the early mechanical properties of artificial sand concrete, we found by comparison with natural sand concrete that the slump of artificial sand concrete were increased by 85%, and the strength 0f 16h and 1d and3d were increased by 23.4% and 20% and 11%. Therefore, artificial sand can significantly improve the workability of concrete mix, improve the early strength of concrete.

2016-2-28  Properties of Molding Material Dry Strength ` It is the strength of the molding sand in dry conditions. ` When the molten metal is poured in the mold, the sand around the mold cavity is quickly converted into dry sand as the moisture in the sand evaporates due to the heat of the molten metal. ` At this stage the molding sand must posses the sufficient strength to retain the exact shape of

Mechanical behavior and constitutive model of methane

2021-7-6  Calcareous sand is porous and fragile, and its mechanical properties are significantly different from that of homogeneous quartz sand (He et al. 2017; Li et al. 2021). Laboratory shear test is one of the main precautions to study the mechanical behavior of soil or rock, and can provide data reference for avoiding or reducing the geological risk
