The Strength of Compression Sets Quality Standards

Over the years, our choices have changed. However, our demands remain the same. The generation before us believed in the inner strength of any material. They choose that material to build their homes that can withstand the maximum load. The materials that comprise the roads, highways, and bridges are strong enough to withstand the maximum load. Although we have to try our hands in modern technology and designs in building making and road construction, our desire for choosing quality building materials is still there. The structure of our automobiles has also transformed over the years. The present generation believes in having trends with strength. Before any building construction, locomotives, bridges, or roads, it is necessary to perform the compression test with compression testing machines.

Facts about the Compression Test

A compression test is evaluating the compressive strength of any material with the help of compression testing equipment. Compressive strength is one of the most important characteristic features of many materials. It is an evaluation procedure where a material like cement faces an opposing force by the equipment. The specific part of the equipment that imparts the pressure is in the opposite direction of the material. The machine squashes or flattens the material on a platform. The net force that successfully flattens the material is measured and the time taken by the material to become flat gives the compressive strength of the material. The compression testing apparatus comprises two pistons and a base platform with the force of the top piston presses against the second piston at the bottom. You can measure the compressive strength of the concrete. It occurs by placing a block of concrete on a metal platform. The force with which the first piston presses against the other piston flattens the concrete block. It finally gives the net compressive strength of the concrete.

Components of the Compression Test

Among some of the chief components in the compression testing apparatus, load frames are the one. The choice of the load frames depends on the requirement of appropriate stroke and force. The load frames can be vertical-single types or dual horizontal types. The dual-horizontal types are for large and heavy samples and, the single vertical frames handle comparatively smaller sample sizes.

There is another component called the load cells. The type of load cell selection occurs on the immediate test requirements. The load cell is a type of sensor that measures the force put on the sample material. The load cells generally operate at a lower force. However, periodic calibration will maintain them in good condition.

Cube Test Procedure of Compression Test

Concrete is one of the major constituents in building construction. Before the construction of a building, measuring the compressive strength of the concrete is necessary. The compression test occurs in a steel testing machine. The machine has the capacity of holding the cement cubes of about 16cm in diameter.

The concrete cube turns solid for 24 hours after placing them in water for about a week. The expert places the solid cube inside the testing machine. The continuous load falls on the block of concrete by the two pistons of the testing machine. The net force that initiates crack in the concrete block gives the net compressive strength.

The cube test procedure is a simple method to measure the compression in the concrete material. It is a quality assurance test. It states that the experts can use this concrete in building construction in a hassle-free manner.
