Konkriti ndi mtundu wa zinthu zomangira zomwe zipani zambiri zomanga pano. Ngati pali konkriti pa konkriti pakumanga, pomwe kukungika kuli kokulirapo, ndikosavuta kuyambitsa kutsekeka kwa konkriti, kuchititsa kuchepa kwa kukhazikika. Kukhazikika kwa konkire kumakhudzana mwachindunji ndi chitetezo cha nyumbayo. Chifukwa chake, ndikofunikira kuti muchepetse konkriti, yomwe ilinso vuto la magulu ambiri omanga.
Pochita, nthawi zambiri timagwiritsa ntchito superplasticizer ndi mchere wambiri, womwe umatha kukwaniritsa zofunikira pantchito, koma vuto la konkriti silingakonzeke, tsopano tikugwiritsa ntchito wothandizila ambiri, yemwe angathandize kwambiri kulimbana kwa konkriti komanso kuletsa ming'alu . Poyerekeza ndi shrinkage kuchepetsa othandizira ndi zopangira ma fiber, kusakaniza wothandizila kukulitsa konkriti ndi njira yodula, makamaka kugwiritsa ntchito wothandizila yemwe poyamba anali zinyalala za mafakitale ngati zinthu zopanda pake, zomwe zimathandiza kwambiri kugwiritsidwa ntchito kwa zinthu. The vanadium iron slag ndi zinyalala zolimba zopangidwa ndi kusungunulira, zomwe zimatha kulipirira shrinkage, kusunga kukhazikika kwa konkriti, komanso kukhala ndi ntchito ya hydration. Chifukwa chake, ndikuyenda bwino kwake, ndikotheka kusintha gawo lazomwe zimagwiritsidwa ntchito pakukula kwa calcium sulphoaluminate ndikukhala watsopano mu msika wa konkriti. Ubwino wake ndi awa:
Choyambirira, monga kuphatikiza kwa simenti yochokera pazinthu zopangira simenti, Ferrovanadium slag ali ndi chidziwitso chokwanira cha shrinkage. Ikagwiritsidwa ntchito konkire ya nkhope, imatha kubwezeretsa shrinkage, kuchepetsa ming'alu ya konkriti komanso kukonza kukhazikika. Kuwona kwathunthu pazinthu zosiyanasiyana monga kupikisana mwamphamvu, pogwiritsa ntchito zoyesa mosamala za sayansi, zitha kutsimikiziridwa kuti zinthu zopangira simenti zimakhala bwino komanso zosagwirizana ndi gawo la vanadium ndi iron slag ndi 15% ~ 20%.
Kachiwiri, kuphatikiza konkire komanso kopingasa kwa konkriti yosakanikirana ndi phulusa lokha, vanadium slag ndi phulusa la ntchentche ndizokwera kuposa za simenti yosalala, makamaka ya konkriti yosakanikirana ndi vanadium slag ndi phulusa louluka. Zomangamanga zenizeni zimawonetsa kuti 20% vanadium iron slag ndi 10% phulusa lothandizira akamagwiritsa ntchito m'malo mwa simenti ndikuphatikizidwa ndi konkriti, kugwiritsa ntchito kumakhala bwino pamagulu awiri olimbitsa.
Kugwiritsa ntchito Ferrovanadium slag kuti musinthe simenti, ngakhale mukuthandizira ntchito za simenti, kapena kugwiritsa ntchito zinyalala za mafakitale, kumathandiza kwambiri, osati kuteteza ming'alu ya konkriti, komanso kupulumutsa zida ndi kuteteza chilengedwe.
Katundu wotsogola wa Puguang Teqi ndi galimoto yaying'ono yama pampu ya konkriti ya 25-46m yaung'ono komanso yaying'ono yokhala ndi zopindulitsa kwambiri pakukonzekera bwino komanso mtengo wokwera mtengo. Nthawi zonse chimatsatira lingaliro lautumiki la "kukhulupirika kwambiri, msika wosintha ntchito", ndipo limayesetsa kumanga bizinesi yopanga zanzeru yozindikira ntchito.
