  • Main frame
  • Standard

a) The use of advanced AC servo motor speed regulation drive system, speed regulation ratio of 1:10000, according to the needs of the acceleration speed of 0.05-100mm/ min to achieve any pressure plate rise speed;
b) Full mechanical structure, from servo motor to servo reducer, the use of fully sealed structure, no need to replace the lubricating oil during use, there is no pressure oil leakage and proportional valve blockage;
c) The main engine is designed in accordance with ergonomic standards, making the operation simple, convenient and fast. Measurement control with high precision and intelligence;
d) Give full play to the advantages of the microcomputer, reduce the electronic control system hardware, and integrate all electrical parts into two modules, which greatly improves the reliability of the product;
e) Exceeding a certain range of the maximum test force (overloading 2-5% of the gear), or when the piston hits the limit, it can be stopped immediately;
f) Each measurement data can be stored permanently for later observation;
The test force and displacement measurement control are concentrated on the test interface of the microcomputer, which is intuitive and easy to operate.

The main engine of the pressure testing machine is a gantry frame composed of two columns, upper beams, a base plate and a table. The transmission mechanism is composed of AC servo motor, belt, reducer and precision screw to realize the up and down movement of the mechanical piston, so as to realize the movement of the specimen pressure plate. Complete the compression experiment. Its compact structure and smooth transmission. The mechanism ensures that the frame has sufficient stiffness while being smooth and efficient. In the process of testing, the load sensor on the upper beam determines the size of the test force, the microcomputer software controls, the compression test is automatically completed, and the data is collected and printed.

ISO 679 cement compressive and flexural strength test method

ISO 679 determining the compressive strength (and optionally flexural strength) of cement, using a standardized mortar mix rather than testing pure cement paste or concrete. It is the benchmark that allows different cements from different plants and countries to be compared on a level playing field.

ASTM C109 Compression Testing of Cement Mortar

ASTM C109 is the fundamental test method for determining the compressive strength of hydraulic cement using 2-inch (50-mm) mortar cubes. It specifies a standardized procedure to prepare, cure, and test 50-mm (2-in.) cube mortar specimens for compressive strength. The mortar mix ratio is 1 part cement to 2.75 parts standard sand (by mass). For Portland/air-entraining Portland/Portland-limestone cements, water content is fixed; for other cements, water is adjusted to achieve a flow of 110±5 (per 25 drops on a flow table, ASTM C230). Specimens are compacted in two layers by tamping, cured, and loaded in compression until failure to calculate strength as peak load divided by cross-sectional area.
