Pozzolanic activity of palm bunch wastes
Abstract The paper reports an investigation of the ash from the burnt stalks of oil palm bunches as a suspected agricultural waste with pozzolanic activity. Chemical analysis confirmed the presence of the major elements silica, alumina, potassium and a comparatively low content of calcium, all of which are necessary for pozzolanic activity. Limestone, shale, lead and sodium carbonates were independently mixed with the ash to improve the pozzolanic activity, which was low without the introduction of these conditioners. It was confirmed that limestone together with lead carbonate are good additives that can enhance pozzolanic activity in the ash. The ash was therefore classified as a pozzolana which can be used to produce pozzo-lime cement or used as a blender with ordinary Portland cement.
