PARTIAL REPLACEMENT OF CEMENT IN CONCRETE BY STEEL SHOT DUST

Leaving the waste mater ials to the environment can cause various environmental problem s . Hence the attention is on the reuse of the waste material . Waste can be used to produce new products or can be used as admixtures so that there is more use of natural resources and the environment is protected from waste deposits. Automobile industries produce both solid and liquid waste products.The waste produc t which we are using is also a solid waste product, namely Steel Shot Dust. Steel Shot Dust is a very fine powder of steel shots. This dust is produced in the process of shot blasting. There are very limited recycling solutions available for steel shot dus t, that too on an experimental phase only. Also, the options available for recycling are big - budgeted , whereas the recycling we are experimenting on doesn't involve any type of extra expenditure. We are using this waste to prepare the blocks of concrete of grade M25 with th e replacement at 5%, 10% and 15% percentages . The compression test is applied to the blocks at 7 days and 28 days respectively.
