Oil Palm Shell Ash - Cement Mortar Mixture and Modification of Mechanical Properties
The waste agriculture materials cause environment pollution, recycle of these materials help sustainable development. This study focused on the impact of used oil palm shell ash on the compressive and flexural strengths of cement mortar. Two different cement mortar mixes have been designed to investigate the impact of oil palm shell ash on strengths of cement mortar. Quantity of 4% oil palm she...
متن کاملPerformance Evaluation and Microstructure Characterization of Metakaolin-Based Geopolymer Containing Oil Palm Ash
This study reports on the microstructure, compressive strength, and drying shrinkage of metakaolin (MK) based geopolymers produced by partially replacing MK by oil palm ash (OPA). The OPA was used as raw material producing different molar ratios of SiO₂/Al₂O₃ and CaO/SiO₂. The geopolymer samples were cured at 80°C for 1, 2, or 4 hours and kept at ambient temperature until testing. The compressi...
متن کاملBinary Effect of Fly Ash and Palm Oil Fuel Ash on Heat of Hydration Aerated Concrete
The binary effect of pulverized fuel ash (PFA) and palm oil fuel ash (POFA) on heat of hydration of aerated concrete was studied. Three aerated concrete mixes were prepared, namely, concrete containing 100% ordinary Portland cement (control sample or Type I), binary concrete made from 50% POFA (Type II), and ternary concrete containing 30% POFA and 20% PFA (Type III). It is found that the tempe...
متن کاملUse of disposed waste ash from landfills to replace Portland cement.
In this study, waste ash was utilized as a pozzolanic material in blended Portland cement in order to reduce negative environmental effects and landfill volume required to dispose of waste ash. The influence of waste ash, namely palm oil fuel ash, rice husk ash and fly ash on compressive strength and sulfate resistance in mortar were studied and evaluated by some accelerated short-term techniqu...
متن کاملPore Structure Changes of Blended Cement Pastes Containing Fly Ash, Rice Husk Ash, and Palm Oil Fuel Ash Caused by Carbonation
In this paper, the effects of carbonation on pore structure of blended pozzolan cement pastes were investigated. Ordinary Portland cement OPC was partially replaced with ground palm oil fuel ash POA , ground rice husk ash RHA and classified fine fly ash FA . The strength, total porosity, specific surface area, and pore size distribution were tested. In general, incorporation of pozzolans increa...
