摘要：
The impact compression tests on HPP hybrid fibers reinforced lightweight aggregate concrete were performed with 100mm SHPB equipment. The dynamic mechanical properties and variation of HPP hybrid fibers reinforced lightweight aggregate concrete under different strain rates and loading methods were systematically studied. HPP hybrid fibers reinforced lightweight aggregate concrete is of the property of strain rate effects under impact loads as ordinary concrete. The dynamic strength and peak strain of it increased with the increase of strain rate. During multiple-impact compression tests, the specimens were able to bear multiple impacts before damage after cracks were produced. It is clear that HPP hybrid fibers reinforced lightweight aggregate concrete is an outstanding material for protective engineering to resist repetitive impacts.
