Frequently Asked Questions

 Concrete cover blocks (also known as RCC spacers or cement spacers) are used to maintain a specified distance between the reinforcement bars (rebar) and the surface of concrete. This ensures proper concrete cover as per IS code standards, which protects the steel from corrosion, moisture, and fire. 

 Plastic spacers are lightweight and cost-effective but can deform under heat or load. Concrete cover blocks are strong, fire-resistant, and provide better bonding with the structure, making them ideal for heavy-duty RCC construction. 

The size of the cover block depends on the type of element—slab, beam, column, or footing—and the required cover specified in the structural drawing or IS 456:2000 code. For example, slabs may require 20mm to 25mm cover, while footings may need up to 75mm. 

RCC cover blocks provide consistent cover to reinforcement, prevent corrosion, improve fire resistance, and ensure compliance with structural codes. They also help in maintaining the correct alignment and spacing of steel bars during construction.
