In this context an experimental
study is done based on Quarry Dust Wastes
(QDW) and polypropylene plastic granules
(PPG) for replacement of fine aggregate in
concrete. The strength properties of M40
grade concrete is studied with different
proportions of plastic granules and quarry
dust along with addition of 1% super
plasticizer. The various proportions of plastic
and quarry dust used are 25% and 30%
replacement by volume of river sand in the
concrete. Strength tests are carried out with
different proportions of replacements of river
sand with QDW and PPG. Cube specimens,
cylinder specimens and prism specimens of 9
numbers each were cast for different
proportions of M40 concrete , cured and
tested for 7 ,14 and 28 days. Compression,
split tensile and flexural strength tests were
done and the results are compared with
100% river sand concrete specimens.
