Concrete is an artificial stone made by mixing cement, aggregates (such as sand, stone), water, and admixtures (such as fly ash, slag, etc.
) in a certain proportion.
Its main performance includes strength, durability, and construction performance.
The strength of concrete is a comprehensive reflection of indicators such as compressive strength, tensile strength, and flexural strength; Durability involves resistance to freeze-thaw, permeability, and chemical erosion, among others; The construction performance includes characteristics such as fluidity, drop retention, and setting time.
