Ikhonkrithi luhlobo lwezinto zokwakha ezisetyenziswa ngamaqela amaninzi okwakha okwangoku. Ukuba kukho ukuqhekeza kwikhonkrithi ngexesha lokwakha, xa ukuqhekeka kukhulu kakhulu, kulula kakhulu ukubangela ukuvuza kwesakhiwo sekhonkrithi, okubangela ukwehla kokuqina. Ukuzinza kwekhonkrithi kuhambelana ngokuthe ngqo nokukhuseleka kwesakhiwo. Ke ngoko, kubaluleke kakhulu ukuba kuncitshiswe ukuqhekezwa kwekhonkrithi, okwangxaki enkulu kakhulu yamaqela amaninzi okwakha.
Ukuziqhelanisa, sihlala sisebenzisa i-superplasticizer kunye nokudibanisa amaminerali, ezinokuthi zihlangabezane ngcono neemfuno zomsebenzi, kodwa ingxaki yekhonkrithi yokuqhekeka ayinakuphuculwa, ngoku sisebenzisa iarhente eyandisayo, enokuthi iphucule kakhulu amandla okulwa nekhonkrithi kunye nokuthintela ukuqhula. . Xa kuthelekiswa ne-arhente yokunciphisa i-shrinkage kunye ne-synthetic fiber, ukuxuba iarhente yokwandiswa kwikhonkrithi sisikimu esisebenza ngendleko, ngakumbi ukusebenzisa iarhente yokwandisa eyilahla inkunkuma yezemveliso njengezinto eziluhlaza, eziphucula kakhulu umgangatho wokusetyenziswa kwezixhobo. I-vanadium iron slag yinkunkuma eqinileyo eveliswa kukunyibilikiswa, okunokuhlawula i-shrinkage, ukugcina ukuzinza kwekhonkrithi, kunye nomsebenzi we-hydration. Ke ngoko, ngokusebenza kakuhle, kunokwenzeka ukuba ubuyiselele iarhente eyandisiweyo yokusetyenziswa kwecalcium kwaye ube yinto entsha oyithandayo kushishino lekhonkrithi. Izibonelelo zako zezi zilandelayo:
Okokuqala, njengokudityaniswa kwezinto ezisekwe kwisamente, i-Ferrovanadium slag inefuthe lembuyekezo ye-shrinkage. Xa isetyenziswe kwikhonkrithi yobuso bekhonkrithi, inokubuyisa ngokufanelekileyo i-shrinkage, inciphise ukufihla kwikhonkrithi kunye nokuphucula ukuqina. Ukuqwalaselwa ngokupheleleyo kwemiba eyahlukeneyo njengamandla okucinezelela, ngokusebenzisa uvavanyo olunononophelo lwezesayensi, kungangqinwa ukuba izixhobo ezisekwe sisamente zinobunono obungcono kunye nokumelana nokuqhekeka xa umda we-vanadium kunye ne-slag eyi-15% ~ 20%.
Okwesibini, amandla oxinzelelo kunye nobunzima obuthathaka kwikhonkrithi exutywe nothuthu kuphela, i-vanadium slag kunye ne-flying ash iphezulu kunaleyo yekhonkrithi ecocekileyo yesamente, ngakumbi leyo ikhonkrithi exutywe ne-vanadium slag kunye nothuthu lwendiza. Olona lwakhiwo lubonisa ukuba xa iipesenti ezingama-20 ze-vanadium i-slag kunye ne-10% ye-ash isetyenziswa endaweni yesamente kwaye ixutywe kwikhonkrithi, isiphumo sesicelo sihle kwiiprojekthi ezimbini zokomeleza iipaneli.
Ukusetyenziswa kwe-Ferrovanadium slag ukubuyisela isamente, nokuba kungokusebenza kokusebenza okusekwe kwisamente, okanye ekusebenziseni inkunkuma yamashishini, kudlala indima enkulu, kungekuphela nje ekuthinteleni ukungcola kokhonkrithi, kodwa nokukhusela izixhobo nokukhusela okusingqongileyo.
Imveliso ekhokelayo kaPuguang Teqi yitrust yecrete yekhonkrithi encinci kunye ephakathi nendawo kunye nexabiso eliphambili lobuchule kunye nexabiso elifanelekileyo lokusebenza. Ihlala ibambelela kwingcamango yenkonzo "yomgangatho ophethe ukuthembeka okunzima, ukuphuculwa kwenkonzo kwimakethi", kwaye izabalazela ukwakha ishishini elenza inkonzo eluntwini.
