Explanation

Generally, it refers to prestressed reinforced concrete. Generate pre-stress by tensioning steel bars. The prestressed reinforced concrete mouth is used to improve the tensile capacity of products and components, prevent and delay the occurrence of concrete cracks, and make full use of high-strength materials to greatly improve the crack resistance, stiffness and durability of products or components, reduce the dead weight and save raw materials. According to the method of tensioning steel bars, the generation of prestress can be divided into mechanical method, electric heating method, and chemical method. According to the time of applying prestress, it can be divided into pre tensioning method and post tensioning method.
