Self compacting concrete with partial replacement of sand by waste foundry sand

Abstract

In the past few years use of Self Compacting Concrete (SCC) is growing tremendous and much research and
modification has been done to produce self compacting concrete which has the desired characteristics. Generation of
waste foundry sand as byproduct of metal casting industries causes environmental problems because of its improper
disposal. The current area of research in self compacting concrete is introducing foundry sand in self compacting
concrete. This project demonstrates the use of waste foundry sand as partial replacement by fine aggregate in self
compacting concrete. An experimental investigation is carried out on a self compacting concrete containing waste
foundry sand in the range of 0%, 10%, 20%, 30%, 40% by weight for M35 grade self compacting concrete. Material was
produced, tested and compared with ordinary self compacting concrete in terms of strength. These tests are carried out
on standard cube, cylinder and beam for 7 and 28 days to determine the mechanical properties of self compacting
concrete. The aim of this research is to know the behavior and mechanical properties of self compacting concrete after
addition of industrial waste in different proportion by tests like compressive strength, split tensile and flexural strength.
The research is a resource for exploring the potential use of foundry sand as alternative to virgin raw materials.
