Litsi tsa motlakase oa mashala United States li hlahisa hoo e ka bang 75 lithane tse limilione tsa molora oa mashala selemo le selemo. Ha e bapisoa le 267 lithane tse limilione tsa lithōle tseo Maamerika a li hlahisang ka selemo, it makes sense to find alternative uses for coal fly ash to keep landfills from being overwhelmed with this residual matter.
Ka lehlakoreng le letle, liphesente tse ka bang mashome a mahlano a metso e robeli tsa molora oa mashala o hlahisitsoeng ka 2018 e ile ea sebelisoa bocha. Mokhoa o mong oa ho etsa joalo ke ho o sebelisa ha ho etsoa konkreite. The Romans used a mixture of volcanic ash mixed with lime to create a very effective kind of concrete. It was invented Long before portland cement.
sebedisa fly ash from coal-fired power plants creates a similar chemical reaction when used in the production of concrete, e etsang hore e be sebaka se loketseng bakeng sa phapanyetso ea samente. The significance of keeping fly ash out of landfills is huge, empa ho na le ho hongata ho tekano ea tikoloho.
Ha samente ea portland e fola, it leaves behind some of the hydrated lime. That is added with water to create a binding agent. Ha molora oa fofa o sebelisoa sebakeng sa samente, e lumella kalaka ho fola le eona. Contributing to added strength and durability of hardened concrete in comparison to cement alone.
motuya koleka, e fokotsa haholo matla a hlokahalang ho hlahisa samente ea portland. Hoo e batlang e le thane ea carbon dioxide e hlahisoa tlhahiso ea samente ea portland. While it is already combusted and therefore does not release additional CO2 upon being used in concrete. Bakeng sa thane e 'ngoe le e' ngoe ea samente e nkeloa sebaka ke molora oa fofa ka motsoako oa konkreite, it can avoid a ton of carbon dioxide emissions.
Recycling fly ash does help to keep landfills from being overburdened. Ho ekelletsa moo, e boetse e fokotsa bongata ba matla a hlokahalang ho hlahisa konkreite hammoho le boka ba carbon dioxide bo ntšetsoang sepakapakeng nakong ea tlhahiso ea konkreite.
Senotlolo sa matla le ho tšoarella ha lihlahisoa tsa moaho tse entsoeng ka molora oa fofa ke ho fokotsa boleng ba eona ba khabone le ho laola boleng ba eona. The ST Helmets & Technology ea triboelectrostatic lebanta kgaoganyo can remove residual carbon coal char and generate a high quality consistent processed product, ProAsh®, thepa ea bohlokoa bakeng sa bahlahisi ba konkreite. Re ikemiselitse ho thusa bareki ba rona le lefats'e leo re phelang ho lona. Iteanye le rona kajeno bakeng sa tlhaiso-leseling e batsi.
