Comparative Study of Waste Glass Powder Utilized In Concrete

Every year approximately 2.35 billion tons of cement is produced - that is almost 1 m3 of cement for every person in the world. The carbon dioxide released into the atmosphere during the cement production process accounts for approximately 5-10 % of the overall CO2 production in the world. Its release into the atmosphere contributes to the global warming and the development of holes in the ozone layer. If the CO2 production in cement factories could be decreased by 10 %, the overall release into the atmosphere would decrease by 5.2 %. Using waste glass as cement replacement in concrete construction sector is advantageous, as the production cost of concrete would decrease, and our industry would become more environmentally friendly. The large scale production of Portland cement and the acquisition of aggregates from dredging and quarrying have a dramatic impact on the environment. Consequently extensive research is ongoing into the use of Portland cement replacement. The concept of utilizing waste material for building applications has a long and successful history. These once problematic, land filled waste materials are now considered valuable commodities for use in enhancing certain properties of concrete, so the main purpose of this paper is to find out the strength of concrete containing waste glass powder as pozzolana. Cement replacement by glass powder in the range 5 % to 20 % in increments of 5 percentages (5 %, 10 %, 15 %, 20 %, and 25 %) has to be study.
