Why is Lightweight foamed concrete
Lightweight foamed concrete is usually prepared by introducing foaming agents such as hydrogen peroxide and plant surfactants into cement paste to form high pores and voids in the matrix. A foaming agent is a material that facilitates foam formation, such as a Surfactant or a blowing agent. Foaming agents are used extensively in air mist drilling to produce high, stable foams under various conditions. It reduces surface tension and is effective in fresh water and salt water. In this study, it was concluded that foam concrete prepared by mixing cement 60 and 40% with detergent of 0.4% by weight of cement be the best possible mix out of the selected mix ratios without compromising the engineering properties of concrete. Inorganic foaming agents are made from inorganic carbonate and sodium bicarbonate. Inorganic foaming agents improve the efficiency of the foaming process through endothermic reactions. Nausea, constipation, diarrhea, or headache may occur. Foam concrete is a type of lightweight concrete. The density of the concrete can be reduced by introducing stable voids in hardened cement paste. The stone aggregates in regular concrete are replaced by foam in foamed concrete. Standard concrete is made from cement, sand, stone aggregates, and water, whereas foamed concrete is made of cement, sand, foam, and water. For foamed concrete at the lowest densities, sand is not used either. The common foaming agents for polyurethane are organic solvents, whose residues in the scaffold may harm adherent cells, protein growth factors, or nearby tissues. Water was used as a foaming agent, and NaCl was used as a porogen to achieve an open-cell structure. Foaming agent is a material. When present in small amounts, a surfactant reduces the surface tension of a liquid or increases its colloidal stability by inhibiting the coalescence of bubbles. The foam have two types: wet foam and dry foam. Wet foams with densities lesser 100 kg/m3 are not recommended for manufacturing foam concrete. Foamed concrete is ideal for filling voids such as disused fuel tanks, sewer systems, pipelines, and culverts – particularly where access is difficult. It is a recognized medium for the reinstatement of road trenches.
