Development of Bottom Ash as Pozzolanic Material

Comprehensive Characterization of Grounded Bottom Ash from Indian Thermal Power Plant

“…F type ash upholds excellent self-hardening capacity [28,36]. Cement product formed by reaction of hydrate lime or moisture with silica and alumina, which are present in grounded bottom ash having fine particulates [18,22]. Grounded bottom ash samples contain lower percentage of loi as compared to original bottom ash and therefore, it corroborates more pozzolanic nature.…”

“…Bottom ash is commonly used for land-filling but huge amount is still remains unused, which can be used commercially by grounding. after grounding it imposed to pozzolanic properties almost similar to fly ash and having high commercial value [18,28]. F type ash upholds excellent self-hardening capacity [28,36].…”

“…Due to advantages of easily lugged, the light weight concrete members utilized as offshore structures [38][39]. The grounded bottom ash is also suitable for backfilling of excavations, tunnels, sewers, and other underground facilities [18,40]. The fine coal ash can be used for making of roller-compacted concrete [41].…”

“…Presently, bottom ash is utilized in civil engineering applications like road construction, concrete, structural fill, agriculture, embankment and geotechnical applications [14][15][16][17]. in response of the environmental issues of bottom ash, many investigators [15][16][17][18][19][20] have emphasized on maximum bottom ash utilization methods with the aim to minimize the reclamation and disposal. the bottom ash particles are the coarser in nature having large particle size and high porous surface which offer the high water requirement and lower compressive strength.…”

The Effect of sieved Coal Bottom Ash as a Sand Substitute on the Properties of Concrete with Percentage Variation in Cement

“…and Rocha et al, [2] reported that because the bottom ash porosity was high, the w/c ratio of the concrete could not be accepted as accurate, whereas Chai Jaturapitakkul and Raungrut Cheerarot [3] reported that the bottom ash had a potential high enough to function as a good pozzolanic material. Rafat Siddique [15] conducted a detailed investigation on the mechanical properties of various concrete mixtures in which fine aggregates were partially replaced with class F fly ash by weight.…”
