Ukhonkolo luhlobo lwezinto zokwakha ezisetshenziswa amaqembu amaningi okwakha njengamanje. Uma kunokuqhekeka kukakhonkolo ngesikhathi sokwakha, lapho ukuqhekeka kukhulu kakhulu, kulula kakhulu ukubangela ukuvuza kwesakhiwo sikakhonkolo, okuholele ekunciphiseni kokuqina. Ukuqina kukakhonkolo kuhlobene ngqo nokuphepha kwesakhiwo. Ngakho-ke, kubaluleke kakhulu ukunciphisa ukwehla kokhonkolo, okubuye kube yinkinga ekhathazeke kakhulu yamaqembu amaningi okwakha.
Ekusetshenzisweni, sivame ukusebenzisa i-superplasticizer kanye ne-ammiamo admiamo, engahlangabezana kangcono nezidingo zomsebenzi, kepha inkinga kakhonkolo ayikwazi ukuphuculwa, manje-ke sisebenzisa i-ejenti eyandisa, engathuthukisa kakhulu amandla we-anti ufa kokhonkolo futhi ivimbele imifantu . Uma kuqhathaniswa ne-ejenti yokunciphisa i-shrinkage kanye ne-synthetic fiber, ukuxuba i-ejenti yokwandiswa kukakhonkolo kuwuhlelo olusebenzisa izindleko, ikakhulukazi ukusebenzisa i-ejenti yokwanda okuyi-imfucumfucu yezimboni njengezinto ezingavuthiwe, ezithuthukisa kakhulu isilinganiso sokusetshenziswa kwezinsiza. I-vanadium iron slag imfucumfucu eqinile ekhiqizwa ngokuncibilikisa, enganxephezela ukubumbana komoya, ukugcina ukuzinza kukakhonkolo, futhi kube nomsebenzi we-hydration. Ngakho-ke, ngokusebenza kwayo okuhle kakhulu, kungenzeka ungene esikhundleni se-ejenti esetshenziswa evamile ye-calcium sulphoaluminate futhi ube yintandokazi entsha embonini yekhonkrithi. Izinzuzo zalo zimi ngokulandelayo:
Okokuqala, njengokuhlanganiswa kwezinto zokwenziwa usimende, i-Ferrovanadium slag ine-isinxephezelo sesinxephezelo se-shrinkage. Uma isetshenziswa kukakhonkolo obuso bekhonkrithi, ingavimba ngempumelelo i-shrinkage, inciphise ukuqhekeka kokhonkolo futhi ithuthukise ukuqina. Ukucatshangelwa okuningiliziwe kwezici ezahlukahlukene njengokuqina okuqinile, ngokusebenzisa ucwaningo lwesayensi ngokucophelela, kungafakazelwa ukuthi izinto ezakhiwe usimende zinokuncintisana okungcono nokuqhekeka lapho ingxenye ye-vanadium ne-iron slag ingu-15% ~ 20%.
Okwesibili, isilinganiso sokuqina kokhonkolo esixutshwe ne-fly ash sodwa, i-vanadium slag ne-fly ash kuphezulu kunale kukhonkolo kakhonkolo omsulwa, ikakhulukazi lokho kukakhonkolo okuhlanganiswe ne-vanadium slag kanye nomlotha wendiza. Ukwakhiwa uqobo kukhombisa ukuthi lapho kusetshenziswa i-20% ye-vanadium iron slag no-10% umlotha esikhundleni sosimende futhi kuxutshwe ukhonkolo, umphumela wokufaka isicelo muhle kumaphrojekthi amabili wokuqinisa iphaneli.
Ukusetshenziswa kwe-Ferrovanadium slag ukufaka okunye usimende, noma ngabe ekuthuthukiseni ukusebenza kwezinto ezakhiwe kusimende, noma ekusebenziseni imfucuza yezimboni, kudlala indima enkulu, hhayi nje ukuvimba imifantu ekhonkolo, kepha futhi nokusindisa izinsiza nokuvikela imvelo.
Umkhiqizo ophambili kaPuguang Teqi uyiloli elincane eliphakathi nendawo neliphakathi nendawo eliphakathi nendawo elinezinzuzo ezihamba phambili kwezobuchwepheshe kanye nezindleko ezinhle kakhulu zokusebenza. Ihlala inamathela embonweni wesevisi "wekhwalithi ephembelela ukwethenjwa okukhulu, ukuthuthukiswa kwensiza emakethe", futhi ilwela ukwakha ibhizinisi elenziwa ngemisebenzi elihlose insizakalo.
