Portland cement, as an ingredient in concrete, is one of the widely used construction materials, especially in
developing countries. The CO2 emission during its production and the utilisation of natural resources are important issues
for the construction industry to participate in sustainable development. These days the waste materials of industries is on
its way to increase day by day due to strict environmental policies and this waste contains SCMs generally. They can be
utilised not only to improve properties of concrete but also to prevent pollution due to reduction in carbon dioxide
emission. Steel slag aggregate generally exhibit a propensity to expand because of the presence of free lime and
magnesium oxides hence steel slag aggregates are not used in concrete making. Proper weathering treatment and use of
pozzolanic materials like silica fume with steel slag is reported to reduce the expansion of the concrete. The effect of
oxide composition of the binder material used, on the strength and durability properties of concrete is also investigated.
