Abstract

Due to rising environmental concerns and resource depletion linked to sand mining, alternative materials are essential to meet construction demands. Dredged sediment (DS) offers a potential solution by providing a locally available and sustainable replacement. This study explores the feasibility of using DS from Sungai Pusu, Gombak, as a sustainable partial replacement for natural sand in concrete production, potentially providing a regionally sustainable alternative and aiding waste reduction. Material characterisation shows that DS sourced from Sungai Pusu contains insignificant amounts of hard metals and does not require extensive treatment. Concrete specimens, sized 150 mm × 150 mm × 150 mm, were prepared with 0%, 15%, and 30% DS substitution levels and cured for 7 and 28 days. Results indicate that concrete with 30% DS substitution demonstrates significant improvements in strength, highlighting feasibility of DS from Sungai Pusu as an eco-friendly alternative for sustainable construction practices.
