At the site rehabilitation or upgrading of reinforced concrete members using the enlargement of the cross-section, bonded steel plates was an effective, convenient, and economic method of improving structural performance. However, disadvantages inherent in the use of steel or traditional enlargement of the concrete elements, where possible, have stimulated research into the possibility of using fiber reinforced polymer (FRP) materials in its place, providing a non-corrosive, more versatile strengthening system. The need for repair and strengthening may arise from deterioration, changes in use, changes in the relevant design codes, structural defects, or seismic conditions.
Foam concrete technique is also known as Lightweight Cellular Concrete (LCC) with property of Low Density Cellular Concrete fill material produced by blending of a cement paste. Foam concrete is created by uniform distribution of air bubbles throughout the mass
