Abstract

Palm oil fuel ash (POFA) is a by-product waste material from palm oil with many economic and environmental benefits. A lack of enough information on the advantages of POFA in the concrete production in various proportions was the main cause to carry out this work. This paper shows advantages of POFA as a partial replacement of cement in concrete production, especially cement mortar. The data collection has been done from the literature review related to the use of POFA as partial cement replacement in the production of cement concrete and mortar. Therefore, this paper can potentially become a guide for researchers and manufacturers to use POFA in various proportions to replace the ordinary Portland cement (OPC) in cement concrete and mortar. The positive and negative impact resulting from this material has been discussed carefully. This study recommends that researchers and academics should perform more experimental works in order to illustrate the desired benefits from POFA as cement replacement, thus mitigate the adverse environmental impacts of cement.

Highlights

South-east Asian countries produce the most products from oil palm, which grows their abundantly owing to their geographical and ecological conditions [1, 2]
Malaysia and Indonesia contribute to the largest production of palm oil in the world which was more than 80% of the total production, just 10% of that palm oil is used to cover the local demand and 90% is exported [5, 6]
Farzadnia et al [29] conducted a study on the 30% Palm oil fuel ash (POFA) as cement replacement in concrete mix, it was noted that drying shrinkage was reduced by 7.5 % within 28 days due to the addition of Nano silica to the concrete mix

Summary

Introduction

South-east Asian countries produce the most products from oil palm, which grows their abundantly owing to their geographical and ecological conditions [1, 2]. Increasing the production of palm oil leads to the generation of a huge quantity of waste materials such as POFA [10] that have high content of silica and serious effects on the surrounding environment if not used in other industries.
