| Summary: | Plastic waste aggregate for concrete is a vast communicating topic nowadays due to overusing and depletion of natural sands
and gravels. Despite efforts, plastic waste aggregates (PWA) still weaken concrete due to inadequate particle interaction.
Incorporating clay particles into plastic particles is a wise step to mitigate this issue. Water-assisted melt compounding is a
promising process for intercalating clay particles into polymer particles. The performance of recycled biaxially-
oriented polypropylene composite aggregate (PCA) is highly dependent on the manufacturing processing parameters. In this
study, the effect of water-assisted melt compounding process and formulation parameters using a Haake internal mixer on the
tensile property of the PCA was investigated. The processing parameters (temperature and duration), clay and water content,
called independent variables, were optimized to maximize the response (tensile strength) using response surface methodology
(RSM) via a two-level full factorial design. The selected model accurately analysed the interaction between the parameters, with
the coefficient of determination approaching a unity of more than 0.9633. |
