Disposal of high amount of fly-ash from thermal power plants absorbs huge amount of water, energy and land area by ash ponds. Therefore, fly-ash management would remain a great concern of the century.
Fang et al. [52] used steel slag and fly ash instead of some cement, and under the optimal conditions of the composite ratio of cement, steel slag powder, and fly ash of 12:5:3, it was found that the moderate addition of steel slag can effectively improve the compressive strength of concrete and improve the activity of cement, while the ...
Fly Ash Concrete. Fly ash is used as a replacement for Portland cement in concrete, it replaces up to 30% by mass of Portland cement, but can be used in higher percentage in certain applications. In some cases, fly ash increases concrete's final strength and its chemical resistance and durability.
Many recent pieces of research were successful in finding that the use of SCMs like silica fume, blast furnace slag, fly ash, metakaolin, rice husk ash, etc., can enhance the properties of concrete but can be economical in construction [7]. In particular, the abundance of rice husk (the source of rice husk ash) in many parts of the world ...
Fly ash has been widely used as a cement substitute to improve the sustainability of concrete. Although the advantages of fly ash have been extensively …
So far several uses of fly ash have been developed viz. substitute of cement in concrete, land filling, mine filling, agriculture, etc. Practically fly ash consists of all the elements present in ...
Fly Ash-Based Eco-Efficient Concretes: A Comprehensive Review of the Short-Term Properties. by. Mugahed Amran. 1,2,*, Roman Fediuk. 3, Gunasekaran Murali. 4, Siva Avudaiappan. 5, Togay …
Fly ash is a heterogeneous by-product material produced in the combustion process of coal used in power stations. It is a fine grey coloured powder having spherical glassy particles that rise with the flue gases. ... Used in Roller compacted concrete dams. Used in the manufacture of fly ash bricks; When flyash is treated with silicon hydroxide ...
Integrating artificial intelligence and green concrete in the construction industry is a challenge that can help to move towards sustainable construction. Therefore, this research aims to predict ...
The data on the compressive strength of concrete after fly ash and rice husk ash had been added in percentage increments of 0%, 10%, 20%, 30%, 40%, 50% and 0%, 5%, 7.5%, 10%, 12.5%, 15% ...
The disposal of fly ash has been causing a severe headache to the environmentalists all across the globe. The effective utilisation of fly ash is restricted only to manufacture of bricks ...
Results show that fly ash (164 kg CO 2 eq, 54% reduction) and GGBS (141 kg CO 2 eq, 61% reduction) reduce the global warming potential of pure-cement …
17. CONCLUSION: Fly ash thus holds a vast potential for improving the modern day concrete when it comes to quality in the long term. In spite of being an industrial waste, it can improve durability and reduce heat of hydration. The prospects of fly ash are still being underused even today.

Most of the literature has reported on the use of eggshell powder with fly ash, metakaolin and rice husk ash as a precursor in high strength concrete and cement mortar. Download: Download high-res image (660KB) Download: Download full-size image; Fig. 10.
20.2.4.4 Bricks Manufacturing. The synthetic pozzolanic character of FA is because of the constituents accomplishing amorphous silicate minerals. Usually pozzolanic ash does react with slaked lime and water to form the complex, i.e., CaO–Al 2 O 3 –SiO 2 –H 2 O (Çiçek and Çinçin 2015).The fired clay type bricks have been used on masonry …
