The coating of cement on the surface of steel bars protects them from corrosion and chemical effects. Join The Discussion. When rebar corrodes, the oxidation products expand and tends to flake, cracking the concrete and unbonding the rebar from the concrete. Cost effective construction material when it comes to certain structures like dams, footings, and piers. Each building needs separate consideration. During our inspections, we often observe cracks and spalls in the concrete perimeters of the balconies. B. 3. Fire resistance. 1- Reinforced concrete has a high compressive strength compared to other building materials. Therefore, no internal stresses are set up within reinforced concrete due to the temperature change. Fire and weather resistance of reinforced concrete is fair.
