Abstract

With the help of SHPB apparatus, do the research on the energy transfer rule, strength characteristics and failure pattern of complete mortar testing piece and specimens with 1~3 joints, under the similar impact speed. In addition, regarding the double parallel cracks specimens as an example to explore how the impact speed regularly influenced the degree of damage of the specimens. Experimental results show that under the same incident energy condition, as the joint number increasing from 1 to 3, the more joints, the heavier destruction of specimens which appear the pattern of multiple blocks. And there is a negative relationship between dynamic compressive strength and the number of joints testing pieces. The results of this study provide a reference for the analysis of the dynamic characteristics of laminated cement mortar material in construction engineering.
