Strength Of Cement Mortar

Jun 08, 2012Mortar 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

Properties of Fresh and Hardened Concrete – Basic Engineering

Sep 01, 2019The strength of concrete depends upon the amount of cement content, quality and grading of aggregates, water cement ratio, compaction and curing. Strength of concrete is gained in the initial stages. In 7 days the strength gained is as much as 60 to 65% of 28days strength. It is customary to assume the 28days strength as the full strength of
