Properties of Concrete During the first week to 10 days of curing it is important that the concrete not be permitted to freeze or dry out In practical terms about 90 of its strength is gained in the first 28 daysthe first 28 days Concrete compressive strength depends upon many factors quality and proportions of the ingredients

Average 28 days compressive strength of at least three 150 mm concrete cubes prepared with water proposed to be used shall not be less than 90 of average of strength of three similar concrete cubes prepared with distilled water

Compressive Strength Tests on Concrete Masonry Blocks If the bearing area of masonry unit is more than the bearing area of steel blocks then separate steel plates are used The plates are arranged on steel blocks in such a way that the centroid of masonry unit coincide with the center of thrust of blocks

May 18 2018 Concrete being the major consumable material after water makes it quite inquisitive in its nature The strength of concrete is majorly derived from aggregates whereas cement and sand contribute binding and workability along with flowability to concrete This is an indepth article on Compressive Strength of Concrete
