Experimental Analysis of Partial Replacement of Glass Powder and Fly Ash with Different-Different Percentages of Cement to Improve the Compressive and Flexural Strength of Concrete

Abstract: The ordinary material for construction is concrete in India and its production causes some environmental effects during the production. There are many countries seeing deficiency of human dumping wastes or it’s becoming very serious day by day for each nation. In order to deal with atmospheric impact related with cement manufacturing and so there is a requirement to produce an alternative binding material for preparing concrete. The development of concrete could reducing the utilization of naturally occurring sources or lesser the load of pollutants on atmosphere. In current scenario, no. of researchers have recognized the uses of additional cementing materials like silica fumes, fly ash, glass powder, rice husk ash, blast furnace slag etc. It could also change the different properties of hardened and freshen state of concrete, and also contributing the financial system in constructional cost. Efforts put on the concrete construction to mix fly ash and waste glass powder as half substitute with cement .Now a days Glass used in different way in day-to-day life. As glass is non-biodegradable, landfills don’t provided an environmental eco-friendly resolution for dumping. Fly ash containing large amount of silica in comparison to cement. In current scenerio lots of industries producing more quantity of fly ash or its sold out very cheapest price in market. Glass is an inert material which could be recycled and used several times without altering its chemical property. Glass is an amorphous material which having high % of silica content. This property makes it probable pozzolanic property when its particles sizes is less than 75 mm. An important anxiety related to the uses of glass powder in concrete mix is that is chemical reaction happen among the alkali in pore solution and silica rich glass particle, which is called Alkali-Silicate. Reactions could be more harmful for the stability parameters of concrete, for this proper safety measure should be taken to reduce its effects. The addition of fly ash in glass concrete reducing the alkalies, silica reaction and improves the workability and durability of concrete. Unwanted glass powder is using for preparing concrete which leads environmental ecofriendly. The main purpose of this study is to find out effectiveness on durability of unwanted glass powder and fly ash based concrete. For analysis it was proposed that the uses of unwanted glass powder and fly ash as half substitution with cement in following proportion (10%, 20%, 30%, 40%) in concrete mix. Compressive strengthening of cubes and flexural strengthening of beams at the interval of 7th, 28th days were considered and compared with the conventional concrete. The results showing the probability of using unwanted glass powder and fly ash as half substitution with cement in concrete.
