The scarcity of natural sand necessitates the use of alternate materials to replace it. This experiment investigates
manufactured sand, a readily sourced industrial by - products waste material in India, as an alternative to natural sand, which is
traditionally utilized as fine aggregate in concrete construction. In this present work the attempt has been made to study the
effect of manufactured sand by partially replacing fine aggregate in concrete with addition of steel fibre and also polypropylene
fibre separately.
