Concrete Mix Ratio: What’s In A Cement Mix And Why It Is Important

Concrete has relatively high compressive strength (resists breaking, when squeezed), but significantly lower tensile strength (vulnerable to breaking, when pulled apart). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete. In other words we can say concrete is made up of sand (which is a fine aggregate), ballast (which is a co… Webb26 juli 2024 · The basic ingredients for that would be 1 cement, 2 sand and 4 aggregate.
