Why cover is used in RCC?
Why we provide Concrete Cover? Covering is provided to arrest the attack of corrosion. If the proper cover isn’t implemented then there is more chance of corrosion and cracks in hardened RCC. Covering is provided For every element of the building (Slabs, Beams, footings) where the reinforcement is used.
How are cover blocks made?
Cover blocks are produced by making cement mortar which consist of cement and sand. Water cement ratio will also impact the strength of cover blocks made. Cement is tested by casting cubes of cement mortar only in proportion of 1:3.
