Development of Uniaxial Restrained and Adjusted Temperature-Stress Testing Machine

In the important basic construction of facilities nowadays, cracking sensitivity is already concerned critically in concrete research fields of many countries. But the relational progress still stays in traditional measuring methods, such as cement heat of hydration. In our research, Concrete cracking is evaluated effectively by restrained testing with the uniaxial restrained and adjusted temperature-stress testing machine (USATTM). The measure parameters include the modulus of elasticity, creep, and the coefficient of thermal deformation. The computer control system is reliable and low-cost. USATTM meets most of the technical indexes and reach to its design demand.
