Inyathelo 1: ukuvavanya ialkalinity yesamente

Vavanya ixabiso le-pH lesamente ecetywayo, kwaye usebenzise i-pH, imitha ye-pH okanye ipeni ye-pH ukuvavanya. Iziphumo zovavanyo zingasetyenziselwa ukumisela kwangaphambili: ingaba inani le-alkali enyibilikayo kwi-samente likhulu okanye lincinci; ingaba i-admixture kwi-samente i-acidic okanye i-inert material efana ne-stone powder, eyenza ixabiso le-pH liphantsi.

Inyathelo lesi-2: uphando

Inxalenye yokuqala yophando kukufumana iziphumo zokuhlalutya i-clinker yesamente. Bala umxholo weeminerali ezine kwisamente: i-tricalcium aluminate C3A, i-tetracalcium aluminoferrite C4AF, i-tricalcium silicate C3S kunye ne-dicalcium silicate C2S.

Inxalenye yesibini yophando kukuqonda ukuba luhlobo luni lwemixube oludityanisiweyo xa iklinka igutyungelwa kwisamente kwaye igalelwe kangakanani na, nto leyo eluncedo kakhulu ekuhlalutyeni izizathu zokopha kwekhonkrithi kunye nexesha lokumisela elingaqhelekanga (inde kakhulu, imfutshane kakhulu).

Inxalenye yesithathu yophando kukuqonda iindidi kunye nokucoleka kwemixube ebambekayo.

Inyathelo lesi-3: Fumana ixabiso ledosi egcweleyo

Fumana ixabiso ledosi egcweleyo yesinciphisi samanzi esisebenza ngokufanelekileyo esisetyenziselwe le samente. Ukuba ezimbini okanye ngaphezulu zokunciphisa amanzi eziphezulu zixutywe, fumana indawo yedosi egcweleyo ngovavanyo lwe-samente yokunamathisela ngokwexabiso elipheleleyo lomxube. Ukusondela kwedosi yesinciphisi samanzi esisebenza ngokufanelekileyo kumlinganiselo ogcweleyo wesamente, kulula ukufumana ukulungelelaniswa okungcono.

Inyathelo lesi-4: Lungisa inqanaba leplastiki ye-clinker kuluhlu olufanelekileyo

Lungisa iqondo le-alkali sulfation kwi-samente, oko kukuthi, i-plasticization degree ye-clinker kuluhlu olufanelekileyo. I-formula yokubala yexabiso le-SD ye-plasticization degree ye-clinker yile: SD=SO3/(1.292Na2O+0.85K2O) Amaxabiso omxholo wecandelo ngalinye adweliswe kuhlalutyo lwe-clinker. Uluhlu lwexabiso le-SD luyi-40% ukuya kwi-200%. Ukuba iphantsi kakhulu, oko kuthetha ukuba kukho i-sulphur trioxide encinci. Umlinganiselo omncinci wetyuwa enesulfure efana ne-sodium sulfate kufuneka yongezwe kwi-admixture. Ukuba iphezulu kakhulu, ithetha ukuba i-molecule inkulu, oko kukuthi, kukho i-sulfur trioxide. Ixabiso le-pH le-admixture kufuneka linyuswe kancinci, njenge-sodium carbonate, i-caustic soda, njl.

Inyathelo 5: Vavanya-xuba imixube edibeneyo kwaye ufumane uhlobo kunye nedosi yeearhente zokumisela

Xa umgangatho wesanti uhlwempuzekile, njengomxholo wodaka oluphezulu, okanye xa zonke isanti eyenziweyo kunye nesanti ecolekileyo zisetyenziselwa ukuxuba ikhonkrithi, emva kokuba uvavanyo lwe-slurry lomnatha lufumana iziphumo ezanelisayo, kuyimfuneko ukuqhubeka nokwenza uvavanyo lodaka ukuze ulungelelanise ngakumbi ukulungelelanisa kunye ne-admixture.

Inyathelo lesi-6: Uvavanyo lwekhonkrithi Kuvavanyo lwekhonkrithi, isixa somxube akufanele sibe ngaphantsi kweelitha ezili-10

Nokuba i-slurry enetha ilungelelaniswe kakuhle, isenokungafikeleli ukulindela kwikhonkrithi; ukuba i-slurry enetha ayilungiswanga kakuhle, ikhonkrithi inokuba neengxaki ezinkulu.Emva kokuba uvavanyo oluncinci luphumelele, ngamanye amaxesha inani elikhulu lifuna ukuphinda liphindwe, njenge-25 ilitha ukuya kwiilitha ezingama-45, kuba iziphumo zisenokwahluka kancinci. Kuphela xa inani elithile lovavanyo lwekhonkrithi luyimpumelelo lunokuthi uhlengahlengiso lokuziqhelanisa lugqitywe.

Inyathelo lesi-7: Lungisa umlinganiselo womxube wekhonkrithi

Unokwandisa okanye unciphise inani lemixube yeeminerali ngokufanelekileyo, kwaye utshintshe i-admixture enye kwi-admixture ephindwe kabini, oko kukuthi, sebenzisa i-admixtures ezimbini ezahlukeneyo ngaxeshanye. Akukho mathandabuzo ukuba umxube ophindwe kabini ungcono kunomxube omnye; ukwandisa okanye ukunciphisa umthamo wesamente kunokusombulula iziphene zokunamathela kwikhonkrithi, ilahleko ekhawulezayo yokudilika kunye nokopha kwekhonkrithi, ngakumbi ukuvezwa kwesanti engaphezulu; ukwandisa kancinci okanye ukunciphisa umthamo wamanzi; ukwandisa okanye ukunciphisa umlinganiselo wesanti, okanye utshintshe ngokuyinxenye uhlobo lwesanti, njengokudityaniswa kwesanti erhabaxa kunye necolekileyo, isanti yendalo kunye nesanti eyenziweyo, njl.
