Light weight aggregate concrete with sawdust and brick ballast

Construction industry relies heavily on conventional material such as cement, sand and gravel for the production of concrete. The river sand and gravels which are most commonly used as fine aggregates and coarse aggregates respectively in the production of concrete, poses the problem of acute shortage in many areas, whose continued use has started posing serious problem with respect to its availability, cost and environmental impact. An attempt is being made in this project to use the locally available waste materials to replace the river sand and gravels to produce light weight and low cost concrete. Sawdust and Brick ballast are easily affordable at low cost or free of cost, which are partially replaced with river sand and gravels respectively for making concrete. Sawdust can be defined as loose particles or wood chippings attained as by products from the sawing of timber into standard useable sizes. Brick ballast is common in the form of over burned bricks. Natural sand and Gravels were partially replaced with sawdust and broken brick ballast respectively.
