Kune zvinhu zvakawanda zvinokanganisa mashandiro edota remafuru uye zvakaoma kwazvo. Zvinhu zvikuru zvinodzora zvinosanganisira: kuumbwa kwemakemikari (kunyanya chikamu chegirazi); chimiro chegirazi; zvikanganiso zvemakemikari uye zvemuviri zvenzvimbo yekushanda mugirazi (kusanganisira izvo zvinogadzirwa nekukuya); mvura Basa renzvimbo yemakemikari; kugoverwa kwehukuru hwezvikamu. Maitiro akawanda pamutsetse wekugadzirwa kwedota remafuru, dota remafuru rinogadzirwa zvakanaka, uye mutengo wedota remafuru unokwira. Asi kazhinji, rinogona kukamurwa muzvikamu zviviri; chimwe makemikari, anonyanya kusanganisira huwandu uye kuumbwa kwezvinhu zvinoshanda zvinotora chikamu mukuita kwepozzolanic reactions; chimwe panyama, iyo inonyanya kukanganisa maitiro emvura uye kuoma kwesimende. Chimiro chedombo resimende chakazogadzirwa gare gare.
1. Zvinhu zvemakemikari
Sezvo chikamu chegirazi che silica-alumina chiri icho chinonyanya kukonzera basa re dota renhunzi, zvinhu zvinoderedza huwandu hwemagirazi, zvakaita sekurasikirwa kukuru pakupisa uye ma crystalline phases akawanda, hazvina kunaka pabasa racho. Pamusoro pezvo, mukuumbwa kwegirazi phase, mabasa ezvinhu zvakasiyana haana kufanana. Ma oxide ndiwo anonyanya kuwanikwa mu dota renhunzi, uye ndizvo zvikamu zvikuru zvezvigadzirwa zvekunyorovesa. Zvisinei, pasi pemamiriro akasiyana ezera uye tembiricha, mwero uye kukosha kwema oxides anobatanidzwa mukunyorovesa kwakasiyana. Semuenzaniso, simbi inogona kuderedza poindi yekunyunguduka kwedota, izvo zvinobatsira pakuumbwa kwema microbeads egirazi. Zvisinei, nekuti iron oxide haina kugona kwakanyanya kwekutora chikamu mukunyorovesa, zvinowanzo fungidzirwa kuti huwandu hwakawanda hwe iron oxide hahuna kunaka pakushanda; huwandu hushoma hwe alkali metal oxides hunogona kukurudzira hydration. Kuita uku kunoitwa, asi kana uchishandisa active aggregate, huwandu hwakawanda hwe potassium ne sodium oxides mu fly ash huchakurudzira kuita kwe alkaline aggregate, nokudaro zvichiparadza kugadzikana kwekongiri; huwandu hushoma hwe sulfur trioxide mu fly ash ine. Inobatsira pakuumbwa kwe hydrated calcium silicate uye kuumbwa kwe hydrated calcium sulfoaluminate (ettringite) iyo inobatsira pakutanga kwesimba, asi kuwedzera kwakanyanya kwe ettringite kunokonzera matambudziko ekugadzikana kwevhoriyamu, saka huwandu hwe sulfur trioxide hahufanirwe kunge hwakakwira pa 3%.
2. Zvinhu zvemuviri
Zvinhu zvikuru zvinokanganisa mashandiro emudota wenhunzi imhando yemagadzirirwo ezvimedu, magadzirirwo ezvimedu nezvimwe zvinhu zvemuviri. Kune mhando dzakasiyana dzemudota wenhunzi, kana mvura inodiwa zvishoma, basa rayo rinokwira; kana kabhoni iri shoma, basa rayo rinokwira; kana kupfava kwayo kushoma, basa rayo rinokwira; kana tichitarisa mafambiro ezvimedu, girazi rakatenderera mudota renhunzi. Kana mudota renhunzi rikawedzera, basa rayo rinokwira. Kubva pachimiro chemudota wenhunzi E, dota renhunzi ine silicon-oxygen ine cheni pfupi, chimiro che tetrahedral chine basa rakawanda.
Nzvimbo chaiyo yedota remafungu inogona kuratidza chimiro chezvikamu uye chimiro chedota remafungu kusvika pamwero wakati. Zvidimbu zvakatetepa zvedota remafungu zvine nzvimbo yakakura chaiyo; muviri wegirazi wakapfuma necalcium une chimiro chakakora uye nzvimbo diki chaiyo chaiyo; kune magirazi akawanda ane maburi. Maburi, nzvimbo chaiyo chaiyo yakafanana yakakura.
