Customers with new buildings and structures often require confirmation that the concrete conforms to the strength requirements they originally established with their building contractor. A crush test (more accurately a compressive strength test) is the way United Scanning usually answers this question.
The 'concrete cube test' is the most familiar test and is used as the standard method of measuring compressive strength for quality control purposes. Concrete beam specimens are cast to test for flexural strength and cast cylinders can be used for tensile strength.
Jul 02, 2012· We design the structural components with C20, C30 C35A concrete and cast accordingly with ready mix concrete. Later we find that the respective 7day, 14 day, 28 day compressive strengths are exorbitantly high (cube crushing strength) compared to what we expected (we expected 2/3 of 28 day strength for 7day, 90% of 28day strength for 14day so on with the specified limitations).

The rate at which concrete sets is independent of the rate at which it hardens. Rapidhardening cement may have similar setting times to ordinary Portland cement. Measurement of concrete strength. Traditionally, this is done by preparing concrete cubes or prisms, then curing them for specified times. Common curing times are 2, 7, 28 and 90 days.
