CONSTRUCTION WORKING USING FOAM CONCRETES THE STUDY OF LIGHTWEIGHT CONCRETE

Foam Concrete can be defines as a type of aerated lightweight concrete; it doesn't contain coarse aggregate (gravel) and can be regarded as an aerated mortar. Foam Concrete can be produce by two methods (Inline Method and Pre-foam Method) where the Foam liquid is added to slurry to form the Foam. The function of Foam liquid is to create an air bubbles in cement–based slurry. The Foam is generated separately by using Foam generator, where the Foaming agent is diluted with water to create the Foam. The Foam Concrete mixture becomes too stiff with lower content, causing bubbles to break, whereas the mixtures becomes too thin to hold the bubbles with high water content, leading to the separation of bubbles from the mixture, water-cement (w/c) ratio usually ranges from (0.4–1.25). The Foam Concrete can be designed to have any density within the dry density range of (300–1850 kg/m3). This project includes study many application of form concrete in construction works
