Cement Concrete Properties Incorporating Waste Foundry Sand

Abstract

In the last few years various research and modification
has been done to produce concrete which has the desired properties.
Concrete is one of the most common materials used in the
construction field. The current area of research in the concrete was
introducing foundry sand in the ordinary concrete. Generation of
waste foundry sand as byproduct of metal casting industries causes
environmental problems because of its improper disposal. Thus, its
usage in building material, construction and in other fields is
essential for reduction of environmental problems. This research
was carried out to produce an eco-friendly concrete. This paper
demonstrates the possible use of waste foundry sand as a partial
replacement by fine aggregate in concrete. Ingredients of concrete
are cement, course aggregate, natural sand (fine aggregate). An
experimental investigation was carried out on a concrete containing
waste foundry sand in the range of 0%, 5% 10%, 15%, and 20% by
weight for M-30 grade concrete. Material was produced, tested and
compared with conventional concrete in terms of strength. The aim
of this research was to know the behavior and mechanical properties
of concrete after addition of industrial waste in different proportion
by tests like compressive strength by cube specimen, split tensile by
cylindrical specimen and flexural strength by beam model. Also the
rebound hammer test was carried out on each cube specimen to
crosscheck compressive strength of concrete. These tests were
carried out at the age of 7 and 28 days of concrete. The research was
a resource for exploring the potential use of foundry sand as an
alternative to virgin raw material that is natural sand.
