Due to incorrect mixing of concrete components or failure to provide concrete cover of the required thickness outside the steel bars, cracks appear on the concrete surface. In addition, due to the inexperience of the craftsmen, cracks appear on the surface of the concrete.

The following defects are caused by the use of defective materials or the inexperience of craftsmen in the construction of reinforced cement concrete.

•  Separation of gravel components. (Spilling)

• Cracks

• Exposure of Reinforcement

1- Separation of gravel components (Spilling)

Sometimes the components made of concrete start to crumble. The reasons for this error are as follows. ,

i- Incorrect ratio of concrete components

ii- Addition of salts, organic matter Insufficient curing of the concrete.

This type of defective construction should be avoided as the age of such construction is very short. A good layer of concrete or tile is laid on top of this concrete.

2- Cracks Of RCC Structures

• Introduction |Purpose And Reason For Crack on Expansion Joints

Due to incorrect mixing of concrete components or failure to provide concrete cover of the required thickness outside the steel bars, cracks appear on the concrete surface. In addition, due to the inexperience of the craftsmen, cracks appear on the surface of the concrete. To correct this, a thorough inspection is done first. If a thin layer of concrete is ruptured, The cement grout is applied on the damaged surface by cutting the affected concrete. Then the surface is corrected by preparing new concrete according to the ratio of the first concrete on it. If the cracks are deep, cement is gritted in the cracks. A grout gun is used for this.

3- Exposure of Reinforcement

• Calculate The Numbers of Items for The Stair Case

• Damp Prove Course Harmful Effects of DPC Causes of Dampness

• Bar Bending Schedule For RCC Beam

The presence of salts or organic matter in the concrete components degrades the surface of the concrete and exposes the steel bars. Less cement content and not providing the required amount of concrete cover on the outside of the steel bars also cause to expose the steel bars. To repair them, they are first thoroughly cleaned with a steel wire brush and The cement is then grouted. A layer of mortar (3: 1) ratio is applied on top of the grout. Apoxy silicon or polyster etc bonds can also be applied before plastering instead of cement grout. Because shrinkage cracks appear in the cement grout after some time.

How To Repair Leaks Roof

Poor construction often causes roofs to drip. This problem is seen during the rainy season. This problem is caused by improper roof joints. In addition, this problem creates on damaging the Damp Proof Course This problem also arises due to the deterioration of the roof surface. The roofs also start dripping due to the growth of grass or other plants on the roofs. If the whole roof is dripping, in addition to the layer of tiles on the roof, a layer of soil is also removed and a layer of Hot Bitumen is applied on the entire roof. Above this layer. Plastic paper is laid out. Then a layer of soil is placed on top of it and then a layer of tiles is laid again. If some areas of the roof usually in drain pipes are affected then only these areas are treated
