Cellular Light Weight Concrete using Glass Fiber

Abstract

Foamed concrete is a material which basically consist of cement based mortar with minimum (atleast ) 20-25 % of air by volume. It has lower strength than conventional concrete. It is a non loadbearing structure element. Now a days investigation is carried out on the concrete blocks by varying density of foam in quary dust. Constro chem foaming agent is a synthetic foam which is used to vary the density of concrete. The main aim of this project is to decrease the density of concrete by using optimum amount of foam. The results are discussed in detail with respect to test conducted such as compressive strength, split tensile strength and flexural strength with varying quantity of glass fibre and foam. In civil engineering works foamed cement concrete can be used in numerous ways as it has unique characteristics which can be exploited in works. Foamed concrete will flow readily from an outlet to fill restricted and irregular cavities, it requires no compaction and it can be pumped by a significant distance or height. Therefore it can be used as a free flowing and self setting fills. This report provides a detailed summary of foam concrete with respect to constituents, production, engineering properties and use.
