Assessing the effect of biomass ashes with different finenesses on the compressive strength of blended cement paste

On blended cement and geopolymer concretes containing palm oil fuel ash

“…X-ray diffraction (XRD) analysis studies have been performed by several [14,20,29] researchers on GPOFA. They demonstrated that the major crystalline phase is alpha-quartz, and they also identified the minor crystalline phases of potassium aluminum phosphate and cristobalite.…”

Ultrafine grinding of fly ash with grinding aids: Impact on particle characteristics of ultrafine fly ash and properties of blended cement containing ultrafine fly ash

“…For a long time, fly ash as a supplementary cementitious material was widely used in the cement and concrete industries. However, the relatively large particles size, low hydration activity and hydration rate of ordinary fly ash, the early strength of cement and concrete containing fly ash is low and the development of strength is also slow, meaning that the amount of fly ash in cement or concrete materials is limited to a certain range and its engineering applications are also subject to certain restrictions [11][12][13][14][15][16][17][18][19][20][21]. Research shows that the smaller the particles size of fly ash, the higher its hydration activity and hydration rate.…”

Valorisation of sugarcane bagasse ash (SCBA) with high quartz content as pozzolanic material in Portland cement mixtures

“…The technological advantages of using pozzolanic materials lie in the enhancement of the mechanical properties and durability of blended Portland cement (7)(8)(9). The environmental advantages of using pozzolans extend beyond the reduction of Portland cement consumption, since the most common pozzolanic materials now used are residues from industry (silica fume and fly ash (10)(11)(12)), agroindustry (rice husk ash (13,14)) and others (15). The current study investigates the valorisation of another agroindustry residuesugarcane bagasse ash (SCBA).…”
