Compression Testing Machine

The Compression Testing Machine is used to determine the compressive strength of concrete cubes, cylinders, and cores — one of the most fundamental and widely performed tests in concrete quality control. The specimen is placed between two platens and a compressive load is applied at a controlled, uniform rate (typically hydraulically) until the specimen fails; the maximum load sustained, divided by the specimen's cross-sectional area, gives the compressive strength.

Concrete is a man made material essentially mixed at site. The properties of concrete depend on its ingredients and vary from mix to mix. Frequents tests for compressive strength are done to ensure that the concrete used is in accordance with designed specifications.

A brief general description of these machines is :This type of Electric-cum-hand operated model consists of :

Loading Unit : The loading unit is of nut type or welded type having a cross head, base and solid state plates. The hydraulic jack is fixed to the base. The platens of the machines are hardened, ground and polished. The upper platen is provided with self-aligning action. To facilitate the testing of various sizes specimens, suitable sizes of spacers are provided.

Pumping Unit : The Hydraulic Pumping Unit is Electrically- cum-hand operated. The loads are measured on load gauges, which are calibrated on against certified proving rings. The pumping unit is fitted with a speed control knob to adjust the pace rate of loading. The load gauges are fitted with micro switches to switch off the motor when the load approaches the maximum capacity. The electrically pumping unit is also fitted with hand operated pump as an option as an option.
