This investigation is carried out on Self-Compacting Concrete (SCC) replacing sand partially with plastic waste granules of High impact polystyrene (HIPS). Fly ash content of 30% is replaced for cement in the binder content of 497 kg/m3 and HIPS granules with varying percentages from 0-40% are replaced for sand in SCC. Water-to-cementitious content ratio of 0.36 is used in all SCC mixtures. Durability analysis on SCC specimens is conducted by water absorption and sorptivity tests at 28 and 90 days curing age. Fly ash fills the pores at interfacial transition zone and sufficient compaction reduced. So, low volume HIPS replacement up to 30% in SCC has lower porosity. Values are linearly declined up to 30% in the both tests at all curing ages. The smooth surface and spherical shape of HIPS granules leads to weak bonding at cement paste and aggregate interface. Thus porosity increases at high volume replacement starting from 40% due to the less packing density in the concrete matrix. Both water absorption and sorptivity values are higher at 40% replacement compared to SCC mixes contained 0-30% HIPS. E-waste HIPS can be incorporated in concrete to solve issues related to environmental pollution and SCC designed with HIPS up to 30% is more durable. © BEIESP.
