Defference Between Crushing And Ultimate Strength Of Concrete

Compressive Strength of Concrete

Compressive strength of 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 Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures Concrete by Mindness and Young gives a general rule The ratio of 28-day to seven-day strength lies between 1 3 and 1 7 and generally is less than 1 5 or the seven-day strength is normally between 60% to 75% of the 28-day strength and usually above 65%

How to calculate the compressive strength of concrete

23/10/2009Best Answer Concrete specimens are tested using the ASTM39 Test Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens by using two samples made from the same test at the same age usually at strength of 28 days old Design engineers use the specified strength ƒc to design structural elements This specified strength is incorporated in the job contract In this construction video tutorial one can gather knowledge on groups of concrete grades of concrete mix ratios of concrete and characteristic compressive strength in N/mm2 Compressive strength or compression strength refers to the capability of a material or structure to bear up loads in an effort to minimize size as against tensile strength which []
