Waste is not only an environmental problem, but also an economic loss. On average Europeans produce 481 kilogrammes of municipal waste per year. An increasing share of this is recycled or composted, and less is sent to landfill. How can we change the way we produce and consume so as to produce less and less waste, while using all waste as a resource?

Mineral admixtures are those admixtures which are obtain from industries. Mostly mineral admixtures are residue of some industries and are used to replace cement and make concrete cheaper. These waste products are used as mineral admixtures so that maximum utilization of wastes is possible. Some waste products also increase workability (ease of handling) of concrete. Mineral admixtures
