Fly ash is the most mineral residue left over from burning coal by coal-fired power plants. Furu molora ke pozzolanic, meaning that it has cementitious properties. It is valuable for use in ready-mix concrete as a partial replacement for Portland cement. hape, it may be used in the manufacture of other building materials such as bricks, lithaele, and blocks.
Ho kenyelletsoa ha molora o fofang ka metsong ea konkreite ho fana ka melemo e mengata bakeng sa merero ea kaho. It is also great for the environment. bakeng sa e 'ngoe, molora o setseng oa fofa ha o hloke ho romeloa ho li-landfill. E 'ngoe, ho hlahisa samente ho hloka ts'ebetso ea lipalo tse phahameng tsa mocheso tse hlahisang tlhahiso ea CO2. If every pound of fly ash is used to replace cement in concrete, hoo e ka bang ponto e le 'ngoe ea CO2 e thibetsoe ho kena sepakapakeng. Bakeng sa kaho, fofa molora ka konkreite e tsoakiloeng offers several advantages versus normal Portland cement-only concrete, ho kopanyelletsa le tse –
Concrete mixed with fly ash requires less water for production, e bakang sehlahisoa sa denser se sa tloaheleheng ho nyenyefala. Sena se etsa hore e be matla ebile e se tloaelo ea ho cheha kapa ho ba le boemo.

The spherical shape of fly ash particles helps to facilitate the movement of the concrete, esita le metsing a fokotsehileng ha a bapisoa le konkreiti e tloaelehileng. Sena se nolofalletsa ho pompa, bonolo ho e beha, and easier to mold, mme e baka pheletso e boreleli ka lintlha tse hlakileng.
Samente ke eona e theko e boima ka ho fetisisa ea konkreite e tsoakiloeng. Ka ho sebelisa molora o fofang sebakeng sa sona, it can create a better product that is less expensive to produce. Sehlahisoa se betere se theko e tlaase ho se etsa ke tlhohonolofatso ho ba shebelletseng.

The ST Helmets & 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, lets'oao letšoao ProAsh®. Ts'ebetso ea STET e ka sebelisoa ho li-ash tse nchafalitsoeng kapa tse hlahisitsoeng ka khale.
