The Study Involving Partial Replacement of Slag Sand in Polymer Modified Concrete and its Application in Interlocking Concrete Paver Block (ICPB)

Abstract

The idea of Carriageway design and maintenance needs to be such that it bears loads due to the climate change and also for the social comfort which caters the all range of people who use the road way. In this study the potential of the paver blocks is evaluated in the laboratory. Styrene-Butadiene rubber induced paver blocks will have greater tension, good ductility and also, good impact strength because of the 3D polymer network. The bridging between cracks and also due to voids filling nature, the porosity decreases. A Styrene-Butadiene rubber polymer induced along with granular slag sand in ICPB to improve the ductility and flexure of polymer modified concrete (PMC). The structural properties of PMC in paver blocks are studied, the study is divided into two series, Series 1 is to cast paver blocks solely of granular slag sand and Series 2 is to cast paver blocks of PMC where fine aggregates with few parts replaced with Granular slag sand. The comparative study is done for various strength parameters. The study concludes that the paver blocks with PMC concrete with 15% of Granular slag sand replaced with fine aggregates.
