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 100 strength over time at the hardened statethe compressive strength of concrete Otherwise the compressive strength of concrete is defined as the maximum crushing stress endured by the concrete Purpose of this Test Assume a slab at our site is designed to cast M25 grade of concrete but we could not define its strength in the semi solid state
