Concrete Delamination- Causes, Effects, and Precautions
Concrete delamination is the detachment of thin layers of concrete from the concrete surface. The peeled-out concrete surface then becomes prone to all kind of abraders in the atmosphere which consequently weaken the structure. It, therefore, becomes extremely essential to find the area to be remedied before it spreads any further.

Surfactant aggregates and their stability in relation to
Surfactant molecules are removed from the surface by adsorption onto or dissolution in the soil. Finely divided hydrophobic silica particles break the foam by adsorbing surfactant molecules from the bubble surface and carrying them into solution. The presence of certain types of soil in a surfactant solution shows decreased foaming due to this ...

Concrete Slab Surface Defects: Causes, Prevention, Repair
The appearance of blisters (Fig. 1) on the surface of a concrete slab during finishing operations is annoying. These bumps, of varying size, appear at a time when bubbles of entrapped air or water rising through the plastic concrete get trapped under an already sealed, airtight surface. Experienced concrete finishers
