Abstract
The process of palm oil refining produces spent bleaching earth (SBE) as a waste by-product. In Malaysia, this waste usually ends up in landfills. Recycled from SBE, spent bleaching earth ash (SBEA) is a sustainable product that is increasingly integrated as a blended cement in construction applications. It has the potential to be used as supplementary cementitious material and partially substitute cement that contributes to carbon dioxide emission. This research seeks to determine the pozzolanic reactivity of untreated and calcined SBEA. Strength Activity Index (SAI) according to the British Standards, Frattini test, and saturated lime test used to measure the pozzolanic reactivity. Results indicated that both the untreated and calcined SBEA have pozzolanic reactivity. Based on Frattini and saturated lime results, both samples show high pozzolanic activity. However, in all tests, untreated SBEA shows higher pozzolanic activity compared to calcined SBEA.
