Durability outcomes of Self-Compacting Concrete (SCC) produced from recycled plastic aggregates including High Density Polyethylene Plastic (HDPEP) as partial substitute for natural aggregates also with specified mineral admixtures like Silica Fume (SF) as partial substitution of Portland cement is investigated. Durability efficiency of such mix proportions has been evaluated employing Rapid Chloride Penetration Test (RCPT), water absorption test, sorptivity test, electrical resistivity tests and acid attack test on SCC samples developed per five percent partial replacements of natural aggregates with plastic aggregates been for 28 and 90 days curing periods.The inclusion of silica fume by volume of Portland cement about 15 percent was required to account for the lack of durability characteristics. The surface and intrinsic water absorption levels have been noticed to be relatively low of partial substitution with plastic aggregates for SCC samples. Results obtained of durability parameters have been within permitted standards and displayed outstanding efficiency of plastic aggregates in SCC. The added advantage of silica fume, which including pozzolanic activity, functions as a significant contributor to long-term sustainability profitability.Plastic waste substitution for conventional materials in concrete often counteracts for the issue of dumping and preserves renewable resources because plastic wastes are scarcely processed in India, though a significant percentage of plastic products being literally discarded to landfills pose more ecological consequences.
