Compressive Strength of Concrete Cubes - Lab Test & Procedure

According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 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 the hardened state. Take a look at the below table.
