Palm-based lightweight concrete system: A preliminary study

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A palm-based polyurethane system was used as a polymeric phase in a concrete system. It comprised of palm kernel oil-based polyol (PKO) reacted with 2, 4-methylene diphenyl isocyanate (MDI). A development on the formulation of the polymer concrete in achieving the lowest possible density at an optimal level of PU system was conducted. The PU system in the concrete mixture comprised of 5 to 50% w/w PU targeted a density of less than 1800 kg/m 3. The rise time, indicating the end of reaction time was obtained at 80 s. The lightweight concrete undergone a phase change in 5 to 8 min. Excessive PU in the concrete generated more bubbles and resulted in the existence of voids. Optical microscope analysis was carried out. PU system comprised of palm-based polyol and MDI at a ratio of 1:1 was favored with loading of 20-30% w/w in the concrete mixture in order to produce a lightweight concrete. The specified load bearing structure capability was set above 1500 kg/m3. The palm-based lightweight concretes have excellent compressive strength and thermal insulation characteristics.
