Rapid industrial development has initiated a serious ecological and environmental imbalance due to dumping of industrial wastes. In tune with the global emphasis on waste utilisation for greener and cleaner environment . At the authors labs investigative studies were carried out , on potential use of the common industrial wastes in the country in cement manufacture .The industrial wastes such as fly ash from coal fired Thermal plants and L.D convertor slag , from steel industry can be beneficially used as correctives in cement manufacture through judicious raw mix studies .
The paper discusses the chemico-mineralogical characteristics of these industrial wastes along with the reactivity of the cement raw mixes with and without the use of these wastes as correctives .The quality of the resultant clinker and cement has also been discussed in some details .Studies carried out at the authors indicate that usage of these wastes could substantially enhance the reactivity of cement Raw Mix and lead to improved phase formation in clinker .
The paper illustrates through illustrative case studies, the benefits derived from the usage of these materials at the plant scale.
