ABSTRACT
Cellular (aerated) concrete is a lightweight material composed of cementitious mortar surrounding disconnected bubbles which are formed as a result of physical or chemical processes during which either air is introduced into the mortar mixture or gas is formed within it. Foamed concrete has become more popular in recent years owing to the tremendous advantages it offers over the conventional concrete due to the porous nature, thermal insulation, considerable reduction in materials, fast completion, easy application etc. The use of lightweight foamed concrete offer many benefits and advantages particularly cost saving, fast completion and easy application etc. compared to other materials such as steel and timber. Thus conventional blocks can be replaced efficiently with lightweight foamed concrete construction blocks. Also all industrial wastes can be effectively utilized for the production of foamed concrete, which leads to the protection of environment from unauthorized dumping of industrial wastes. This paper summarizes a review on literature on foamed concrete using the additives as cement and fine aggregate replacements.
