Performance of Copper Slag on Strength Properties as Partial Replacement of Natural River Sand in Self-Compacting Concrete

Abstract

In developing countries like India and China
cement is being used in a large scale due its
developmental activities. Hence they are the one
of the largest cement produces in the world.
Cement industries emit 10% of the world’s total
carbon dioxide. So, India is also produces large
amounts of CO2. Due to usage of large quantities
of concrete we also consume huge amount of
Natural River Sand leading to exploitation.
Nowadays the government decision on sand
mining ban has led to the scarcity of natural
river sand. The solution to this problem is using
the alternate materials like GGBFS and Copper
Slag. The self-compacting concrete is a concrete,
which has an ability to flow and consolidate
under its own weight without need of any
external vibration. In SCC flow property is
achieved by chemical admixtures and stability
and durability is achieved by filler material
which reduced the bleeding in concrete. In this
study is to determine the Mechanical properties
of Self-Compacting Concrete by partially
replacing GGBFS as cementatious material and
Natural River Sand with Copper slag in
different percentages (0%, 10%, 20%, 30%,
40%, and 50%) for M40 grade concrete. The
examinations are done by embracing water
powder proportion of 0.4, functionality tests, for
example, droop stream, V-pipe, L-box tests are
directed according to EFNARC rules at crisp
state. Mechanical properties, for example,
Compressive quality, split elasticity, flexural
quality, Young's modulus tests was directed. It
is
indicated that ideal substitution level
characteristic waterway sand by copper slag
was seen as 40%.
