1. 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.

2. Why Concrete Spacers? 
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 develop between plastic and concrete surface, 
which allow ingress of corrosive gases, which in turn accelerates corrosion.
It is found in studies conducted by Norwegian Transport Authorities that at many 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.
