Abstract: Due to rapid demand and growth in infrastructure, the natural resources are fast depleting. The production of cement and aggregates consume energy which are responsible for increase in concentration of carbon dioxide in atmosphere. On the other hand huge amount of wastes are generated in various fields which are not being utilized other than for landfilling, incineration and a very few reused having a recycle value. Some wastes are biodegradable while others are toxic or harmful to environment. Hence there appears to be an urgent need to search for alternative materials, which can replace existing ingredients partially or fully, thereby reducing energy consumption and reduced CO2 emission. This paper discusses some options which appear to be promising in this direction
