compressive strength of cement concrete

Compressive Strength of Concrete Cubes - Civilology- compressive strength of cement concrete ,According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days Why do we test at 7, 14 & 28 days? Concrete is a macro content with Sand, Cement,Coarse aggregate as its micro-ingredient (Mix Ratio) and gains its strength over time at ,COMPRESSIVE STRENGTH OF CONCRETE - ,Compressive Strength of Concrete RCCStructures Modern Day construction utilizes the efficiency of Reinforced Cement Concrete (RCC) to a great extent.
