Abstract

In current scenario there is demand of light weight structures which should be environment friendly as well, so use of Polystyrene which is nondegradeable and one of the most extensively used plastic, is proposed as an alternative to coarse aggregate in this experimental study. So This study reports the results of an experimental investigation into the properties of polystyrene blocks prepared with using silica fume and fly ash as admixtures respectively, in which coarse aggregate were fully(100%) replaced by expanded polystyrene beads. The design approach of preparing new mixes for experimental study were as per weight batching and confirming to guidelines as per IS 10262:2009. Total seventy two blocks were casted and tested from which thirty six blocks(6 batches - each batch contains 6 blocks) were prepared by using silica fume as admixture and thirty six blocks(6 batches - each batch contains 6 blocks) were prepared using fly ash as admixture. The cement content, water-cement content, sand-polystyrene content and the content of admixture replaced by cement varies from batch to batch as per mix design. The cubes were tested for compressive strength in a compressive strength testing machine after 14 and 28 days of curing period.
