STRENGTH PERFORMANCE OF E-WASTE CEMENT CONCRETE WITH GROUND GRANULATED BLAST FURNACE SLAG (GGBS)

ABSTRACT Electronic waste concrete is prepared by using E-waste and ground granulated blast furnace slag(GGBS). In general processing of e-waste in developing countries leads to adverse human health effects and environmental pollution. Hence the use of E waste is practised as it will reduces the Aggregate cost and provides a good strength for the structures and roads. It also reduces the landfill cost and energy saving. Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product which is then dried and ground into a fine powder. In this project the concrete specimens prepared with e-waste material will be subjected to compressive and tensile strength tests. 12mm and 20mm down coarse aggregates are replaced used as the e-waste material. Different concrete mixes are prepared by replacing normal coarse aggregate with Ewaste material in different ranges like 0%, 20%, 40%, 60%, 80%, 100%. A concrete mix of M30 is taken as the reference mix. Cement is replaced with GGBS with 0% and 10%.The effect of replacement of coarse aggregate by e-waste material and cement by GGBS on properties of concrete are studied for compressive strength and split tensile strength for hardened concrete at the age of 28 days and 90 days.
