[0002] Sulphoaluminate cement is made by calcining raw materials with appropriate ingredients to obtain a clinker with anhydrous calcium sulphoaluminate and dicalcium silicate as the main mineral components, adding different amounts of limestone and appropriate amounts of gypsum to the mixture. It is a hydraulic cementitious material with the characteristics of early strength, high frost resistance, corrosion resistance, high impermeability, expansion performance and low alkalinity. In order to control the quality specifications of construction cement materials, it is necessary to sample and test the performance of cement after production.

[0003] The compressive resistance of cement is an important indicator of product qualification standards.

At this time, the pressure on the cement block is much greater than its own gravity), close the movable protective cover 27, and the flip feeder 11 is stored (the electric push rod 15 contracts and drives the wedge block 16 away from the flip feeder 11. Under the action of its own gravity, the flip feeder 11 flips downward until it is stored in a vertical state), start the detection motor 24 again, and the compression detection module 7 performs compression performance detection (the detection motor 24 continues to drive the detection screw rod 25 to rotate, the two moving frames 5 move closer to each other, and the two pressure plates 702 continue to apply pressure from both sides of the cement block until the cement block is broken. During this process, the pressure sensor 703 feeds back the pressure value in real time; the broken cement block falls down and slides down the blanking plate 30 and is collected in the waste bin 29).
