Compressive Strength Of Concrete Cubes

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.
