“…Furthermore, spherical particles, instead of crushed ones, displayed a higher packing density at the wet state. It was found that FA has a very minimum variation to density due to moisture content comparing to natural soils [ 136 ]. FAs can be more insensitive to moisture content variation than other materials considering their high air void content.…”

Development of sustainable concrete as an alternative to conventional concrete helps in reducing carbon dioxide footprint associated with the use of cement and disposal of waste materials in landfill. One way to achieve that is the use of fly ash (FA) as an alternative to ordinary Portland cement (OPC) because FA is a pozzolanic material and has a high amount of alumina and silica content. Because of its excellent mechanical properties, several studies have been conducted to investigate the use of alkali-activated FA-based concrete as an alternative to conventional concrete. FA, as an industrial by-product, occupies land, thereby causing environmental pollution and health problems. FA-based concrete has numerous advantages, such as it has early strength gaining, it uses low natural resources, and it can be configurated into different structural elements. This study initially presents a review of the classifications, sources, chemical composition, curing regimes and clean production of FA. Then, physical, fresh, and mechanical properties of FA-based concretes are studied. This review helps in better understanding of the behavior of FA-based concrete as a sustainable and eco-friendly material used in construction and building industries.

“…Cement was replaced by fly ash with 5, 10, 15, 20, 25 and 30% and metakaolin by 5,10,15 and 20% with M40 grade of concrete for 7 and 28 days. Split tensile and compressive strength gives best results at 30% fly ash and 15% of metakaolin [21]. The concrete strength augment as the percentage of metakaolin content increase up to 15% of replacement with its cement weight.Metakaolin increases the strength of concrete in comparision with normal concrete [63].…”

“…In concrete, metakaolin is used as replacement material. For every production of one ton of metakaolin leads to 175 kgs of CO 2 emission, which is very less when compared to Portland clinkers [21]. In Tables 1 and 2 physical and chemical properties of metakaolin are tabulated.…”

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.

“…However, POFA could be utilized in the construction components as material as partial replacement of cement [18]. It might be used as cement substitution to obtain better strength than standard concrete due to the silica content in the POFA, which is higher than that of OPC [19]. It was discovered in 2004, Palm oil fuel ash, which had a significant quantity of silica and was crushed to a proper fineness, used to be a pozzolanic material that capable of producing high strength concrete with a 90-day strength of 100 MPa [20].…”

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.
