STUDY OF DRY AND WET CEMENT MORTAR DYNAMIC PROPERTIES

摘要

We performed dynamic tests and studied the dynamic properties under compression of dry and wet cement mortar specimens using the Hopkinson split pressure bar method. As a result, we determined the fracture stresses and their dependence on the applied loading growth rate. It is noteworthy that the strength characteristic of wet material under study is less by 10-15 percent as compared to the dry one.
