Precast Ring 3*1

Precast concrete is made from the primary components of concrete: cement, aggregates (sand, gravel, crushed stone), water, and admixtures, all combined with steel reinforcement for tensile strength. These materials are cast in reusable molds under controlled conditions, cured, and then transported to the construction site. Different types of reinforcement, such as steel bars, wires, or fibers, and various admixtures are used to enhance specific properties like strength, durability, and workability, while specialized molds provide unique finishes and precise dimensions.
