Kongiri rudzi rwezvivakwa zvekushandisa zvinoshandiswa nemapato mazhinji ekuvaka izvozvi. Kana paine kuparara mukongiri panguva yekuvakwa, kana pakapetwa pakawandisa, zviri nyore kwazvo kukonzeresa kusimba kwechimiro chekongiri, zvichikonzera kuderera kwekusimba. Iko kugadzikana kwekongiri kwakanangana zvakananga nekuchengetedza kweichi chivakwa. Naizvozvo, zvakakosha kwazvo kuderedza kukonkita, zvino zvakare chinetso chakawanda chemapato mazhinji ekuvaka.
Mukuita, isu tinowanzoshandisa superplasticizer uye mineral admi mchanganyiko, iyo inogona kuita zvirinani kuita basa, asi dambudziko rekongiri harigone kuvandudzwa, saka ikozvino tinoshandisa wakawanda expansive mumiririri, uyo anogona zvikuru kuvandudza anti kupwanya kugona kongiri uye kudzivirira mapundu . Kufananidzwa ne shrinkage inoderedza mumiririri uye yekugadzira fiber, kusanganisa wekuwedzera mumakonzuru chirongwa chechishandiso, kunyanya kushandisa yekuwedzera mumiriri iyo yakatanga maindasitiri marara sezvinhu zvakasviba, izvo zvinobatsira zvikuru mwero wekushandisa zviwanikwa. Iyo vanadium iron slag imarara yakasimba inogadzirwa nekunyungudusa, iyo inogona kudzosera shrinkage, chengetedza kudzikama kwekongiri, uye kuve ne hydration basa. Naizvozvo, nekuita kwayo kwakanaka, zvinokwanisika kutsiva iyo inowanzo shandiswa calcium sulphoalumrate yekuwedzera mugadziri uye uve mudiwa mutsva muindasitiri yekongiri. Zvakanakira zvadzo zvinotevera:
Chekutanga pane zvese, sekusanganiswa kwezvinhu zve simenti-based, ferrovanadium slag ine pachena shrinkage muripo. Kana ichishandiswa mukongiresi kumeso slab, inogona kunyatso kudzora shrinkage, kuderedza kongiri cracks uye kugadzirisa kusimba. Kunyatsotarisisa kwezvinhu zvakasiyana siyana senge inomanikidza simba, kuburikidza nekuyedza kuongorora kwesainzi, zvinogona kuratidzwa kuti simende-yakavakirwa zvinhu ine zvirinani kupokana uye kupwanya kuramba kana chikamu che vanadium uye iron slag chiri 15% ~ 20%.
Kechipiri, inosimbisa uye inosimbisa simba chiyero chekongiri yakasanganiswa nehururuka maputi yega, vanadium slag uye mapapiro aswa yakakwira kupfuura iyo yekrete simendi yakanyanya, kunyanya iyo yekongiri yakasanganiswa ne vanadium slag uye mapapiro emhepo. Kuvakwa chaiko kunoratidza kuti apo 20% vanadium iron slag uye 10% inobhururuka puti inoshandiswa pachinzvimbo simenti uye ichivhenganiswa mukongiri, mhedzisiro yekushandisa iyi yakanaka mumapurojiti maviri ekusimbisa mapurojekiti.
Kushandiswa kweiyo Ferrovanadium slag kutsiva simende, kungave mukuvandudza mashandisiro esimende-yakatsvakwa, kana kushandisa tsvina yeindasitiri, kunoitisa basa rakakura, kwete kungodzivirira crake cracks, asi zvakare kuchengetedza zviwanikwa nekuchengetedza zvakatipoteredza.
Puguang Teqi's inotungamira chigadzirwa ndeye 25-46m diki uye yepakati siki pombi yekongiri pombi ine yakakosha technical yezvinhu uye yakanakisa mutengo kuita. Iyo inogara ichiteedzera kune pfungwa yebasa ye "mhando ine huremu hwakakura kuvimba, basa rekuvandudza musika", uye inoshandira kuvaka bhizinesi rinotungamirwa nehungwaru rekugadzira bhizinesi.
