Concrete admixture enhances the workability of concrete by its powerful deflocculating and dispersing effect on the cement particles which in turns helps to produce high workable concrete or enables in significant reduction in free water content. The admixture to IS 9103-199 (Amendment 2nd August, 2007).INVESTIGATION ON PARTIAL REPLACEMENT OF E,the replacement of E-wastes as coarse aggregate in concrete. Moreover, due to fast growing construction Industry, the demand for river sand has increased, which tends to use Manufactured sand instead of river sand. The project work is to be conducted on M30 concrete.

Concrete block and paver manufacturers have an opportunity to capitalize on new technology with synthetic aggregate technology. The synthetic aggregate market is a $2 billion industry in the United States, with estimates that only about 25% to 30% of currently available recyclable materials are being utilized.Concrete aggregate alternatives - Appropedia:,When vehicles tires reach the end of their usable life, they can still find some use as a replacement for course aggregate in concrete mixes. Crumb rubber is car or truck tires that are ground up between the sizes of 3 - 10 mm. This mix has very poor compressive strength due to its high air content.Use of Waste Materials As a replacement of,To develop the rubberized concrete mixtures, tire rubber was used to replace theaggregate by weight. In the first rubberized concrete mixture, the chipped rubber
Using SGP in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural resources.
