The Mechanical Properties of Barite Concrete Subjected to Impact Loading

Abstract

In order to understand the mechanical properties of barite concrete subjected to impact loading, use the drop-weight experiment according to the stress, strain and displacement to find out. The experiment is designed in two ways, using different qualities of drop hammers falls in the same height or using the same quality of drop hammers falls in different height. And know the failure process of barite concrete when the area of strain rate is 1.4s-1~4s-1, and making reference to the stress time-history curves, the strain time-history curves and the displacement time history curves, comes to the conclusion that in the case of other conditions remain unchanged the peak load, the loading rate and so on will increase if make the drop hammer heavier or higher.
