Strength of Concrete is a very important aspect during construction. Strength of concrete is obtained by crushing the specimen in from of cubes or cylinders. Engineers carefully design concrete for a particular compressive strength and specimen is tested by applying load in a compression Testing Machine. Where carrying frequently the specimens for testing in a standard laboratory is inconvenient and uneconomical.
With special attachments, the machines can also be used for bricks. Hallow or solid concrete blocks, using appropriate capacity machine. In general a Compression Testing Machine consists of Load Frame with suitable platens and a Pumping Unit with Pressure gauge, either had operated or electrically cum hand operated. Load frame and Pumping unit are connected by pressure pipes.
