➢ Concrete spacer is a small material that helps to arrange, fix the steel floor system in the right position, right design and fix the distance to formwork to ensure the concrete thickness to protect armoured concrete.
2. The use of standard
➢ Distance of frame beam to block / 1md of beam: 40cm.
➢ The protective concrete layer thickness shall not be less than the maximum diameter of the steel used at that position.
➢ Common height of concrete spacer for civil engineering: Beam width from 200mm, 220mm, 300mm, 350mm
➢ According to the standard, the concrete quality of the spacer must be equal to or higher than the quality of concrete used to pour the floor.
➢ With civil houses, homeowners can see structural design drawings to know how much protective layer of iron is for floor steel. From there, the homeowner can order according to concrete spacer that needed to protect steel.
