Regular Concrete Vs. High Strength Concrete

May 18, 2020  The maximum resistance of concrete samples, which is known as the psi strength, which is derived from compression tests, will define if the concrete is high-strength or normal. When testing concrete for compressive strength, when the test is 6,000 psi or more, the concrete will then be classified as high strength.

Difference Between Lightweight Heavyweight Concrete

The key difference between lightweight and heavyweight concrete is the density of the aggregate. Lightweight concrete is made using aggregate whose density is less than 2,100 kilograms per cubic yard (or 131 pounds per per cubic foot), while aggregates with greater densities give rise to so-called heavyweight concrete.

Properties of concrete - Wikipedia

Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). 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.
