Experimental Investigation on Cellular Light Weight Concrete

This project deals with the study of Cellular lightweight concrete using Fly ash as a full replacement for fine aggregate. Foamed concrete is a type of aerated light weight concrete which does not contain coarse aggregate. Cellular light weight concrete with wide range of concrete densities (600kg/m3, 900kg/m3) was studied. In this project, Synthetic based foaming agent is used to produce uniformly distributed air voids in concrete thus making the concrete light in weight. Here 4 cubes, 3 cylinders, 1 beam were casted for each of the two different densities. Thus the results are discussed elaborately with respect to Dry density, Water absorption, specific strength, Fire resistance in addition to Compressive strength and Split tensile strength. Finally Cost comparison between Foamed concrete and Conventional concrete is carried out to determine the economy of construction. This study also aims to provide information about the possible applications of cellular light weight concrete in construction industry today.
