Advantage of Concrete Cover blocks in RCC

Advantages of Concrete Spacers                                                                       

Concrete Spacers prevent rebars from corrosion, protect them from fire to certain length of time and help to provide proper 

transfer of stresses from concrete to steel rebars,by helping provide proper cover to rebars.      

Alternatives to concrete spacers are PVC/plastic spacers.

As plastic is a different material than concrete and has different coefficient of thermal expansion than concrete it does not bond 

properly with concrete. It is observed that hair cracks are developed between plastic and concrete surface, 

which allow ingress of corrosive gases, which in turn accelerates the corrosion.

It is found in studies conducted by Norwegian Transport Authorities, that at many a places, especially in bridges and jetties, 

corrosion was initiated at the locations of plastic spacers provided.

While concrete spacers are made from high strength concrete, these concrete spacers bond perfectly with the surrounding concrete.

Astra Concrete Spacers are made from High Strength, Fibre Reinforced Concrete in a factory with a strict quality control.

The compressive strength of these concrete spacers is not less than 60 MPa.

The breaking loads of Astra Concrete Spacers exceed stipulation made in
