Due to dwindling of natural resources like rocks, sand etc., it has become essential to find alternative materials to these dwindling resources and to use available waste in construction industry. In this paper, an attempt has been made to find source and utility of various waste materials in construction Industry.
Introduction:- Due to dwindling of natural resources like rocks, sand etc., it has become essential to find alternative materials to these scarce resources and to use available waste in construction industry. Properties of waste materials varies from place to place as per source. Though the basic material remains the same but the properties in general and chemical properties in particular and their percentage varies considerably. To quote a simple example, the fly ash at various thermal power stations have more or less similar chemical composition, but the percentages of their chemical composition vary to some extent from one thermal power station to other based on quality of raw material used, the process adopted, temperature maintained etc.
