    Concrete Block Crushing Strength

    Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures Compressive strength of concrete depends on many factors such as water cement ratio cement strength quality of concrete material quality control during the production of concrete etc.Strength Strength is an important property to be looked into before selecting stone as a building block Indian standard code recommends a minimum crushing strength of 3 5 N mm 2 for any building block Table 1 shows the crushing strength of various stones Due to the non uniformity of the material usually a factor of safety of 10 is used.The range of strength for sandcrete blocks specified by N I S 74 1976 is between1 8N mm2 to 2 5N mm2 as the minimum strength The blocks can cope with thermal and moisture conditions and the problem of algae growth on the face of block work during construction is unlikely to affect the strength of the block (Edward 1985).The characteristic strength of concrete is the result of the compressive strength of the concrete cube test The design strength is the required strength of concrete to be designed as per the IS code For example assume that the strength of concrete required M25 and the target design strength.
