QT-300C Automatic compression and folding testing machine is mainly used for the compressive strength of cement and other building materials and the bending test of cement. The machine is composed of three units: electric host, controller and computer control system, which can fully meet the requirements of the loading rate of cement strength test in GB "cement mortar strength Test Method (ISO method)" and solve the closed-loop control of cement loading. Equipped with the necessary fixture (fixture), it can also be used for equal speed loading compressive strength test of brick, stone and other materials.
