![]() ![]() ![]() They are cost-saving, faster completion, and easier application compared to steel and wood.It is usually self-leveling, self-compacting and it can be pumped. ![]() This concrete has a lower density such as 400 – 1600 kg / m3.It is an extremely workable, low-density materials that may comprise up to 50% of entrained air. 2.Foamed Concrete:įoamed aerated concrete is a mortar combine by which air voids formed by adding a foaming agent that performs the function of making pores within the concrete without chemically reacting with the cement.ĭetergents, resin soap, gum resins and siphoning are some foaming agents. It makes expansion to a certain extent depending on the amount of gas produced inside the structure.Īluminum powder gas is the most commonly used operating agent in concrete production. Gas concrete is a mixture of water, cement, and very good aggregate with the final addition of a pore-forming chemical that produces air voids within the aqueous mixture at atmospheric pressure. Types of aerated concrete:īased on the method of pore-formation it is classified into two types as follows: 1.Gas Concrete: Here we will learn about aerated concrete, types, merits & demerits of aerated concrete. It can be used for structural or non-structural purposes, air pores are usually 0.1 to 1 mm in diameter. Aerated concrete is classified as lightweight concrete produced from cement or lime, silica, sand, pozzolanic material that means concrete having an excessive amount of air voids, they are designed to reduce the density of concrete and provide good thermal insulation. ![]()
