اطلاعات بیشترNov 26 32 Compressive strength is an effective way of measuring how much load a surface or material can bear The test for this sort of strength is performed by exerting force downward on top of the object paired with an equal and opposite force exerted upward on the bottomThey have one table for clay masonry and one for concrete masonry and each give the compressive strength of the assembly based on the strength of the unit and the type of mortar If the wall is grouted then the grout simply has to comply with ASTM C476 Specification for Grout for Masonry or be the same strength as the specified strength of
اطلاعات بیشترJun 08 32 Mortar is a mixture of cement and sand in a specified ratio on which the strength of the mortar depends If the mortar is weak then also its compressive strength is very low but if the mortar is a strong one then its compressive strength is also very high The mixture of sand and cement in water is generally weak in tension and is strong in compression that is why when the concrete is 51 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials Values obtained will depend on the size and shape of the specimen batching mixing procedures the methods of sampling molding and fabrication and the age
