Abstract

The present study explores the properties of brick aggregate concrete (BAC) incorporating plastic waste (PW) as a partial replacement of fine aggregates. A total of 108 cylindrical BAC specimens (100 mm × 200 mm) were cast with PW replacing fine aggregates at 0%–10%, using a 1:2:4 volumetric mix and water-cement ratios (w/c) of 0.45 and 0.50. After the slump test, the hardened density, compressive strength, split tensile strength, modulus of elasticity, and Poisson’s ratio were performed at several curing ages. Early-age water absorption and porosity were assessed after 7 days of curing. The test results indicated that the workability of BAC declined with increasing PW content at both w/c ratios, with better workability at 0.50, prompting further studies at this ratio. The hardened density of BAC with PW (BPW) reduced by 0.2–7.4% compared to the control concrete (0% PW). The compressive strength of BPW declined by 13.7–50.0%, 16.8–56.9%, and 16.7–52.0% after 7, 28, and 56 days of curing, respectively. Split tensile strength decreased by 16.0–40.0%, 17.2–41.4%, and 16.7–40.0% at 7, 28, and 56 days, respectively. The modulus of elasticity and Poisson’s ratio decreased by 3.4–10.7% and 8.3–29.2% at 28 days, respectively. Moreover, water absorption and porosity increased by 14.8–67.2% and 18.3–83.5% compared to control concrete. The findings underscore the potential of integrating PW into BAC. Therefore, future research should focus on identifying PW characteristics to ensure BAC performance.
