Experimental Study on Concrete Thermal Conductivity by incorporating Copper and Steel slag

Abstract

This paper examines the thermal conductivity of concrete. The thermal conductivity is
increased by the addition of copper slag and steel slag. Many hit and trial methods have been
done to identify the correct mix proportion of slag in concrete and also to find the
compressive strength of the concrete. From the experiments that have been done, it has been
inferred that 20% replacement of weight of concrete by slag is suitable without any
compromise on strength. Thermal studies have been conducted on the controlled concrete
M30 with and without adding slag separately. The results have been studied and have been
found that the induction concrete attained high temperature faster than the normal concrete
and the heat retaining capacity was also found to be much more than the normal concrete.
The main application of this induction concrete is de-icing and anti-icing in bridge decks and
highways.
