Specification and Quality Control of Light Weight Foam Concrete
Ashish Kurweti,  Ruchi Chandrakar
Concrete is one of the popular and oldest materials widely used in construction project, therefore it has been used extensively in the field of infrastructure and construction since ancient days. The continuous research and development projects in concrete have resulted in the production of various types of concrete. Each type of concrete possesses their own some specific characteristics to get an optimum demand of organization and industrialization. One of the best types of concrete whose popularity increases rapidly now days are light weight foam concrete (LWFC). The synonyms of light weight concrete are Cellular Concrete, Foam Concrete or Aerated Concrete. This project describes the nature of foam concrete, its composition, its properties and its durability.
CLC (Cellular light weight concrete) is another light weight concrete material which are widely used in making infrastructure and high rise building, the main ingredients of making CLC is cement(OPC grade 53), Fly ash (class F),sand (passing 2mm sieve) , foaming agent(protein based foaming agent) used. The target density of Foam concrete in between 800-1600kg/m3.
In this project foam is generated through open air mechanical stirring without using Foam generator and by maintaining foam to water ratio 1:25 which means 1 part of foam is added into 25 part of water. Then after, generated foam is now mixing into the cement slurry (cement, sand and fly ash is used in making cement slurry) and entrained about 30% air by volume into the foam concrete so that it attains a light weight concrete block when became hardening.
Keywords- light weight foam concrete (LWFC), cellular lightweight concrete (CLC), without foam generator, fly ash, foaming agent
