Strength Of Cement Mortar

Jun 08 2012If 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 subjected to tensile the ASTM-Standard then the strength of Get price
