Usage and Characteristics
Cement concrete elastic modulus testing machine can test the compressive elastic modulus of various cement concrete specimens under static force. The compressive elastic modulus of cement concrete refers to the ratio of stress to corresponding strain when deformation occurs. Liangong elastic modulus testing machine has excellent performance and mature and stable technology.
The Liangong elastic modulus testing machine generally chooses the Liangong YAW series pressure testing machine or the WAW series universal testing machine, with excellent performance and mature and stable technology.
