Abstract

World’s most seriously problem is global warming and environment pollution, many reasons are responsible for environment pollution & global warming. Cement industry is one of the major part of this, cement industry contributes 7% of total emmision of CO2 in atmoshphere which is major reason of global warming and environment pollution. Cement is the primary binding material used in various construction work like dam, building, bridges, canal, tunnel and many other. It has the binding property which bind aggregates and sand together to form hard and rigid structure. It reacts with water and gets harden property. But it has some drawbacks like:  cement manufacturing emitts lots of CO2 gas which is harmful for environment.  Cement manufacturing process depends on fossil fuels burning which is natural minerals and is limited and also pollute environment by burning itself.  If there are any alternate to cement by waste products then cement is expensive then other for any project. Cement manufacturing industry is one of the carbon dioxide emitting sources besides deforestation and burning of fossil fuels. The global warming is caused by the emission of green house gases, such as CO2, to the atmosphere. Among the greenhouse gases, CO2 contributes about 65% of global warming. The global cement industry contributes about 7 % of greenhouse gas emission to the earth’s atmosphere. In order to address environmental effects associated with cement manufacturing, there is a need to develop alternative binders to make concrete. Consequently extensive research is on going into the use of cement replacements, using many waste materials and industrial by products. The cost of cement used in concrete works is on the increase and unaffordable, yet the need for housing and other constructions requiring this material keeps growing with increasing population, thus the need to find alternative binding materials that can be used in partial replacement of cement. There are several industrial and agriculture waste product which can be used as pozzolanas or in place of cement like flyash, coconut shell ash which is also economical or sometimes more durable and as well as more strengthing material. The main objective of this study is to determine the alternate of cement in more percentage and reduce cement production in respected ratio to protect environment against global warming and air pollution by CO2 emission.
