Concrete with lower water/cement ratio (down to 0.35) makes a stronger concrete than a higher ratio. Concrete made with smooth pebbles is weaker than that made with rough-surfaced broken rock pieces for example.

  • Fundamentals of Concrete - University of Saskatchewan

    Fundamentals of Concrete Compressive Strength — is defined as the measured maximum resistance of a concrete or mortar specimen to an axial load, usually expressed in MPa (psi) at an age of 28-days. Most general use concrete 20 to 40 MPa (3000 to 6000 psi) High-strength concrete by definition 70 MPa or greater (10000 psi or greater) Concrete Basics In its simplest form, concrete is a mixture of paste and aggregates (sand & rock). The paste, composed of cement and water, coats the surface of the fine (sand) and coarse aggregates (rocks) and binds them together into a rock-like mass known as concrete.
