YUSY 300/600 cement compression testing machine is composed of the electric driving machine, the controller, and the computer-control system. It is used in the compression strength test on building materials such as cement. The close-loop control perfectly meets the demand of loading speed in the cement strength tests according to GB/T17671-1999 (Method of testing cements-Determination of strength). Equipped with some specific fixtures, this testing machine can also be applied to the compression strength tests with constant loading rate on tile, brick, stone, etc. YUSY 300C is an improved from YUSY300 to be used to carry out both the test of compression strength and flexural strength in one machine due to the double-position design. Prolonged constant pressure test is performable.
