Abstract: This work is aimed to examine the strength and durability properties of Self-Compacting Concrete (SCC) replacing fine aggregate partially by volume with e-waste High impact polystyrene (HIPS) granules. In addition, Cement is replaced with fly ash in the optimized binder content of 497 kg/m3 using 0.36 water-to-binder ratio in all SCC mixtures. Compressive strength is studied at 28 and 90 days curing age. Durability tests of SCC such as water absorption and sorptivity are investigated at the age of 28 and 90 days with varying fine aggregate replacement up to 40% at an interval of 10%. The increase in HIPS up to 30% replacement shows a linear declination in the reported values of water absorption, and sorptivity tests at all curing periods. Reduction of compressive strength is minimal at all ages with an increment in the volume of HIPS replacement up to 30%. For SCC mixtures, all test values are within the permissible limits. Different particle sizes of aggregates in SCC achieved continuous gradation. In addition, fly ash contributed its effort acting as filler and holds good bonding at interfacial transition zone. Hence, the reduced porosity helps in improvement of durability properties. This investigation is aided in identifying the excellent durability properties with the both cement and sand replacement by fly ash and e-waste aggregate respectively. Replacing e-waste HIPS as fine aggregate in SCC serves as an eco-friendly multipurpose solution. It compensates the disposal problem, conserves natural resources, and reduces energy, emissions, dead load and cost of concrete production.
