Glass Powder as a Supplementary Replacement of Cementenious Material in Concrete

Today concrete is the most demanded material in the construction world. As day by day increasing construction so concrete demands the large amount of production of cement. 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 greenhouse gases, such as CO2, to the atmosphere. 1 Ton of cement production emits 1 ton of CO2 in the atmosphere. Therefore, to control the environmental effects associated with cement manufacturing, there is a need to develop alternative binders to make concrete. There are many researches is ongoing into the use of cement replacements, by using many waste materials and industrial by products. In the present project finely powdered waste glasses are used as a partial replacement of cement in concrete and compared it with conventional concrete. This work examines the possibility of using Glass powder as a partial replacement of cement for concrete. Glass powder was partially replaced with cement as 10%, 20% and 25%. Glass powder a waste material will be used which improves the compressive strength, durability, flexural strength of concrete at later age. The use of glass powder in concrete prevents landfills.
