Fly ash is the most mineral residue left over from burning coal by coal-fired power plants. Digirta ubaxdu waa pozzolanic, meaning that it has cementitious properties. It is valuable for use in ready-mix concrete as a partial replacement for Portland cement. Sidoo kale, it may be used in the manufacture of other building materials such as bricks, dusiyeen, and blocks.
Intaa waxaa dheer ee ashrey duulista ah ee kujira waxyaabaha la taaban karo ayaa bixiya faa'iidooyin badan ujeeddooyinka dhismaha. It is also great for the environment. Waayo, mid, haraaga duulista ka hadhay uma baahna in loo diro miinooyinka qashinka. Mid kale, Soo-saarista sibidhka ayaa u baahan nidaam leh heer-kulka-kulka-sareeya oo sii daaya uumi-baxa CO2. If every pound of fly ash is used to replace cement in concrete, ku dhawaad hal rodol oo CO2 ah ayaa laga horjoogsaday inay galaan jawiga. Ujeeddooyinka dhismaha, duuli ash ash la diyaariyey offers several advantages versus normal Portland cement-only concrete, lugu daro –
Concrete mixed with fly ash requires less water for production, taasoo abuureysa badeecad cufan oo u nugul yareynta inay yaraato. Tani waxay ka dhigaysaa mid sii xoogeysanaysa isla markaana u nugul jahwareerka ama jahwareerka. Karti yaraanta ayaa bixisa iska caabin-qabow-weyn iyadoo laga fogeeyo qoyaanka iyo kiimikooyinka wadada, kaasoo dumin kara oo fidin kara maadaama heerkulku isbeddelayo xilli ahaan.
The spherical shape of fly ash particles helps to facilitate the movement of the concrete, xitaa biyo yar marka loo eego sida caadiga ah ee la taaban karo. Tani waxay fududeyneysaa bamgareynta, si fudud ayaa loo meeleeyaa, and easier to mold, oo waxay abuurtaa gabagabo fudud oo faahfaahin leh.
Sibidhka waa shayga ugu qaalisan ee la taaban karo ee isku dhafan. Adoo u isticmaalaya ashkooga uumiga bedel ahaan, it can create a better product that is less expensive to produce. Wax soo saar fiican oo ka raqiisan in la sameeyo waa u duco dadka daawanaya xariiqa hoose. Caano, dambaska duusha aan la daweynin badanaa waxay kujirtaa dhuxusha hadhaaga haraaga ah, ama kaarboonka, taas oo saameyn ku yeelan karta wax qabadkeeda ama xitaa awoodeeda loo adeegsado in la taaban karo.
The ST Qalabka & technology electrostatic separation process can treat raw fly ash by removing the unwanted residual coal char. The resulting product is a mineral-rich concrete grade, summad lagu calaamadeeyay ProAsh®. Hawsha 'STET' waxaa loo adeegsan karaa labada dhuxul cusub oo taariikhi ah oo soo saaray dhul-beereed ama ashqaraq duul duul.
