The various testing of aggregates performed by Chemical Analysis Laboratories includes the impact value which gives a relative measure of the resistance to sudden impact while the crushing value gives a relative measure of the resistance to crushing under the applied load. The specific gravity and water absorption are to determine the density of the essentially solid portion of the aggregate.
The concrete is required to support the heavy load in all structures, therefore, it is a must to be tested. Our concrete testing lab tests every component in the concrete mix .
The compression test is used to determine the material behaviour under a load. The maximum stress a material can sustain over a period under a load (constant or progressive) is determined. Compression testing is often done to a break or a limit. The concrete samples could be in the form of cubes or cylinders, and different types of blocks, interlocks, tiles, kerbstone, and so forth.
Cube Testing is a Destructive Testing Method of Concrete Testing, as the cubes are crushed in Compression Testing Machine (Test Method: BSEN12390). The mostly tested cubes in practice are of 150x150x150 size in mm.
The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not.
