Identification of Cracks

Question -1 

a) Crack developed due to compression failure, Required Reinforcement is not provided at top of beam

That can be repaired by required reinforcement

b) Crack due to corrosion of reinforcement, cleraring all loose material and providing additional renforcement and platering.

c)Shear cracks due to shear stress It can be repairable

Question -2 

a) Horizontal crack due to tensile stress.Column is inadequate to resist moment which developed in column

It can be repairable 

b) Corrosion of reinforcement. Due to insuffient of cover. It can be repairable

c) Diagonal cracking, due to inadequate rienforcement It can be repairable 

All repairs are done with clearing loose partical and providing required additional reinforcement with pastering with proper procedure.
