Pane zvinhu zvakawanda zvinokanganisa basa renhunzi ash uye zvakaoma zvikuru. Zvinhu zvikuru zvinodzora zvinosanganisira: kemikari yakagadzirwa (kunyanya girazi chikamu); girazi chimiro; kemikari uye kukanganisa kwemuviri kweiyo activation point mugirazi (kusanganisira izvo zvinogadzirwa nekukuya); mvura Basa remakemikari reaction medium; kugoverwa kwehukuru hwezvikamu zvezvikamu. Kuwanda kwemaitiro pamutsetse wekugadzira madota enhunzi, ndiko kuwedzera kwedota renhunzi, uye kukwira kwemutengo wemadota enhunzi. Asi kazhinji, inogona kukamurwa kuita mapoka maviri; imwe ikemikari, iyo inonyanya kusanganisira nhamba uye kuumbwa kwezvinhu zvinoshanda zvinotora uye zvinokurudzira maitiro epozzolanic; imwe yacho ndeyemuviri, iyo inonyanya kukanganisa hydration process uye kuomeswa kwesimende Iyo simende ibwe chimiro chakaumbwa gare gare.
1. Kemikari zvinhu
Sezvo iyo silica-alumina girazi chikamu ndiyo huru sosi yebasa rekubhururuka madota , zvinhu zvinoderedza nhamba yezvitunha zvegirazi, zvakadai sekurasikirwa kukuru pakupisa uye zvikamu zvakawanda zvekristalline, hazvina kunaka kune basa racho. Mukuwedzera, mukuumbwa kwechikamu chegirazi, mabasa ezvinhu zvakasiyana-siyana haana kufanana. Oxides ndiwo anonyanya kuwanikwa muzvikamukubhururuka madota , uye zvakare ndiwo makuru ezvikamu zve hydration zvigadzirwa. Nekudaro, pasi pezera rakasiyana uye tembiricha mamiriro, dhigirii uye kukosha kwemaokisi anotora chikamu mukuita kwe hydration zvakasiyana. Semuenzaniso, simbi inogona kuderedza kunyunguduka kwedota, iyo inobatsira pakuumbwa kwegirazi microbeads. Nekudaro, nekuti iron oxide ine kusakwana kwakanyanya kwekutora chikamu mukuita kwehydration, zvinotendwa kuti yakawandisa iron oxide yemukati haina kunaka kuita basa; shoma shoma yealkali metal oxides inogona kukurudzira hydration. Mhedzisiro yacho inoitwa, asi kana uchishandisa aggregate inoshanda, iyo yakakwira ye potassium uye sodium oxides munhunzi dota inosimudzira kuita kwealkaline aggregate, nekudaro ichiparadza kugadzikana kwekongiri; shoma shoma yesulfure trioxide mumhepo inobhururuka ine Inobatsira pakuumbwa kwe hydrated calcium silicate uye kuumbwa kwe hydrated calcium sulfoaluminate (ettringite) inobatsira pakusimba kwekutanga, asi yakawandisa ettringite kuwedzera kunokonzera matambudziko ekugadzikana kwehuwandu, saka iyo zviri musulfur trioxide hazvifanirwe kunge zvakakwirira pa3%.
2. Zvinhu zvemuviri
Zvinhu zvikuru zvinokanganisa basa renhunzi madota ndeye particle morphology, microstructure uye zvimwe zvinhu zvemuviri. Kune marudzi akasiyana-siyana enhunzi inobhururuka, zviduku zvinodikanwa zvemvura zvehutano hunoenderana, yakakwirira basa; iyo yakaderera iyo carbon content, iyo yakakwirira basa; iyo diki iyo fineness, yakakwirira basa; maererano ne particle morphology, spherical glass in fly ash Kunyanya, kunowedzera basa renhunzi. Kubva pane microstructure maitiro E, thekubhururuka madotaine pfupi-cheni silicon-okisijeni tetrahedral chimiro ine yakakwirira basa.
Iyo chaiyo nzvimbo yenhunzi dota inogona kuratidza chidimbu kuumbwa uye chimiro chenhunzi madota kusvika pamwero. Zvimedu zvakatsetseka zvedota renhunzi zvine nzvimbo yakakura chaiyo; iyo calcium-yakapfuma girazi muviri ine dense chimiro uye diki inoenderana chaiyo nzvimbo; kune akawanda porous girazi miviri. Makomba, iyo inoenderana chaiyo nzvimbo yakakura.
