Compressive strength - Wikipedia

  

2019-11-4  Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate. In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled

Concrete Compressive Strength - an overview

Concrete compressive strength does not depend on the full hydration of its cement particles but essentially on their closeness. 10,11 In a concrete having a water/cement ratio lower than 0.42, hydration stops when there is no more water to hydrate the cement particles. Below this critical value of 0.42, very fine cement particles can be fully hydrated but only the surface of the coarsest ones
