Study of Partial Replacement by Glass Powder and Crushed Spent Fire Bricks in Concrete

Abstract

The reduction in natural resources requires a substitute for those materials. In order to replace the natural resources used in the concrete many replacements has been made such as replacement of cement by fly ash, silica flume, wood ash, etc., replacement of fine aggregates by quarry dust, copper slag, industrial waste etc., In the present investigation, concrete made of crushed spent fire bricks replacing fine aggregates up to 25% are used to study the strength parameters of M30 grade of concrete. Fine aggregates was replaced with crushed spent fire bricks in proportions 0%, 10%, 15%, 20% and 25% and cement can be replaced by glass powder in varies proportions of 10%, 20% & 30%. No additional catalyst/plasticizers have been used for this project for improving their workability. This paper recommends that glass powder and crushed spent fire bricks can be used as an alternative construction material to cement and sand in concrete.
