Read More2021-6-15 When making concrete, the compressive strength is normally controlled by the water-to-cement ratio, and tensile strength is boosted by additions, often steel, to make reinforced concrete. In other words, concrete is composed of sand (a fine aggregate), ballast (a coarse aggregate), cement (also known as a binder), and water (which is an additive).
