Abstract

The principal reason behind the study carried out here is to diminish the dead load of structures with the potential use of light weight bricks. The study enhanced, with numerous literature study to find out the utilization of Expanded polystyrene (EPS) beads and silica fume in a light weight brick. The light weight brick is formed with the partial substitution of cement with silica fume and the substitution of aggregates with EPS beads. EPS beads are one of the most commonly available non renewable material which is used in packaging industries. It is light in weight as it contains air and have great thermal insulating properties, Minimum thermal conductivity observed by researcher was 0.79 W/moC for brick having 25% EPS. It was studied that the light weight bricks give great compressive quality, as the content of EPS beads increase the quality diminished, compressive strength varies from 2nd class brick (i.e.higher than 7N/mm2) to 3rd class brick(i.e., higher than 3.5N/mm2). The addition of silica fume with cement gives great quality as in strength and provides good durability. It was also studied that there were no changes in the efflorescence with the increase in EPS content of the bricks, less than 10 % efflorescence was found. Therefore, the literature study suggest that the utilization of EPS beads with silica fume in a light weight brick is economical, sustainable, provide good strength as well as it has better thermal resistance and has a very good durability.
