Hence the volume is increased and cracks. The shrinkage cracks will close to different degrees due to different levels of the prestressing force. Then, the prestressing tendon is tensioned. The corrosion of steel develops a huge amount of iron oxides and hydroxide that have a much greater volume than the volume of metallic iron. Firstly, the shrinkage cracks in the reinforced concrete beams before prestressing are simulated. This unusual deformation of concrete results in cracking. The deformation of concrete depends on the type of building materials used in the construction such as bricks, cement concrete blocks, etc. Concretes of different strengths were used, and beams were reinforced with 600 MPa yield strength steel bars. slab etc undergo elastic deformation when loaded. Crack distribution and widths were experimentally examined in a series of reinforced concrete (RC) beams. The different components of the building such as wall, column, beam. The load induced in the structure during construction can also lead to cracking especially at the younger stage when the formwork is removed earlier. Construction Overloads & Early Formwork Removal: Errors in design and detailing such as an inadequate amount of reinforcement, improper design of foundation, precast members and slabs, improper selection of materials, lack of sufficient contraction joints etc may result in excessive cracking.
