Compressive strength involves testing and calculating how well a given specimen, product or material can survive compressive stress. unlike tension, which expands or pulls, compression means a specimen, product or material is shortened or pressed down. compressive strength of a material is the point at which the ...
Concrete and aggregate used in your construction projects has to meet strict regulations and quality standards. as these standards are often compulsory, concrete and aggregate testing by an independent third-party is necessary to help assure compliance.
One of the model in which pavement material can fail is by crushing under compressive stress. a test is standardized by is2386 part-iv and used to determine the crushing strength of aggregates. the aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
