“…The ternary blend produced by combining 10% POFA and 10% MK by weight as a substitute to cement improved the compressive strength and microstructure of mortar exposed to elevated temperatures compared to plain OPC mortar (Usman et al , 2017). By using 5% of POFA replacement in concrete through powder technique, the optimum percentage of both compressive and splitting tensile strength is adopted (Sidek et al , 2020). However, tensile strength and modulus of elasticity decreased at elevated temperatures compared with ambient temperature (Paul et al , 2020).…”

Purpose The purpose of this study is to know the influence of palm oil fuel ash and metakaolin on the strength of concrete and crack resistance of reinforced concrete beam. An ordinary portland cement has been used in the concretes production where it is an important material to be considered due to its nature that reacts with every substance present. During the cement production, a significant amount of carbon dioxide is emitted from the clinker in rotary kiln and lot of energy is required in the production processes. Such an event can be prevented by replacing the part of cement with metakaolin (MK) and palm oil fuel ash (POFA). Aside from being a cementitious alternative, the materials can also contribute to a greener environment and more sustainable building, as POFA is available in Malaysia and may be used to substitute cement and minimize pollution. Design/methodology/approach This study assesses the effect of MK and POFA on the concrete in terms of compressive strength and cracks pattern of the reinforced concrete beam based on the relevant previous studies. Findings From this study, the compressive strength of concrete containing MK and POFA was higher than the control mix with the percentage of improvement in the range of 0.8%–78.2% for MK and 0.5%–14%, respectively. The optimum content of MK and POFA is between the range of 10% and 15% and 10% and 20%, respectively, to achieve high strength of concrete. Other than that, the inclusion of MK to the concrete mix improves the strength of reinforced concrete beams and reduces cracks on the surface of reinforced concrete beams, whereas the inclusion of POFA to the concrete mix increases the cracks on reinforced concrete beams. The cracks appeared within the flexure zone of every beam containing the MK and POFA. Originality/value It was found that the fineness of MK and POFA has a significant influence on the mechanical properties of concrete.

“…It was examined that the 30% POFA with mortar mix achieved a flexural strength of 2.10, 2.44, 4.06 𝑁/𝑚𝑚 2 on 7, 28, and 130 days of curing, which was higher than the control mix. This is happening due to the pozzolanic reaction of POFA, which increase the concrete strength compared to the control mix [65]. POFA has a large percentage of amorphous 𝑆𝑖𝑂 2 which is shown in Table 1 and it react with calcium hydroxide (𝐶𝑎(𝑂𝐻) 2 ) created during the hydration process to produce more calcium silicate hydrate (C-S-H) gel compound and contribute greater strength to the concrete by filling capillary pores and improving interfacial bonding between aggregates and pastes at later ages.…”

The concept of utilizing various types of wastes, such as agricultural dumps and marine by-products, as a partial replacement of cement has gained a great interest to develop eco-friendly and economical mortars for sustainable construction. This study aims to evaluate the feasibility of using palm oil fuel ash (POFA), an agro-industrial waste by-product from palm oil mills and seashell powder (SSP) derived from seashells, a marine waste material partial replacement of cement in mortars. The water to binder (w/b) ratio of 0.49 and the sand to binder (s/b) ratio of 2.54 with 0% to 30% of ordinary portland cement (OPC) by weight was replaced with POFA and SSP, and the resulting mortar samples were tested for mechanical properties and durability in this study. The compressive strength, flexural strength, water absorption, and flow table tests were performed in this study for different percentages of POFA and SSP after 7, 28, and 130 days. The results showed that the 30% POFA incorporated mortars achieved the highest compressive strength (35.12N/mm2), flexural strength (4.06N/mm2), high density with less water absorption (4.79%) after 130 days of curing and the high strength mortar with less water flow (22.2cm) during casting. Also, it found that the 25% POFA and 5% SSP incorporated mortars attained acceptable results as supplementary cementing material. This study suggests that the POFA and SSP incorporated mortars could be used in concrete for sustainable development of construction through the efficient valorization of waste materials.

“…Firstly, silica fume used in 1969 in Norway but was employed in North America and Europe in early's 1980 [9]. The usage of silica fume has been increased worldwide over recent years which can enhance the permeability, strength and durability [10]. Silica Fume used as a partly or complete substitute of cement which increases the concrete properties [11].…”

The present work reviews the various mineral admixtures used in concrete which modifies the concrete properties. In this study, cement is partially or completely replaced by different mineral admixtures such as fly ash, silica fume, rice husk ash, Ground Granulated Blast Furnace Slag, palm oil fuel ash and metakaolin. The strength obtained is different for different mineral admixtures by adding these to concrete. Various concrete characteristics like split tensile, compressive and flexural strength, durability, workability are presented.
