Ntau yam txheej txheem tuaj yeem siv rau Blast furnace Slag

Blast furnace slag tuaj yeem ua tiav rau hauv cov khoom tseem ceeb nrog ntau yam kev siv los ntawm ntau yam txheej txheem. Ua tiav rau hauv slag crushed pob zeb, nws tuaj yeem hloov cov xuab zeb thiab gravel li cov khoom sib xyaw ua ke rau cov pob zeb, cov pob zeb ua kom muaj zog, thiab cov pob zeb ua ntej kev ntxhov siab hauv qab qib 500. Nws kuj yog cov khoom siv hluav taws kub-resistant pob zeb nrog kev ua haujlwm kub hauv qab 700 degree. Nws yuav tsum tau siv los ua cov khoom siv rau kev hnav-tiv taus thiab tiv thaiv txoj kev loj, kev sib tw khiav, lub dav hlau khiav, kev tsheb ciav hlau ballast, cov ntaub ntawv sau rau hauv lub hauv paus thiab cushion txheej, thiab cov dej phwj tuaj kho. Tom qab quenching nrog ib tug loj npaum li cas ntawm cov dej, blast furnace slag yuav ua tau rau hauv nplua-grained dej slag mas muaj iav lub cev, uas muaj peev xwm hydraulic cementitious zog. Nyob rau hauv qhov kev txiav txim ntawm cov activators xws li cov cement clinker, txiv qaub, gypsum, thiab lwm yam, nws qhia tau hais tias hydraulic cementitious zog thiab yog cov khoom siv zoo cement. 70% mus rau 80% ntawm cov cement tsim nyob rau hauv peb lub teb chaws yog tov nrog sib txawv ntawm cov dej slag. Dej slag kuj tseem siv tau los ua cov khoom siv rwb thaiv tsev, ntub dej dov thiab ntub av slag, nplua aggregate rau pob zeb thiab txoj kev engineering; Cov ntaub ntawv txhim kho av, thiab lwm yam.
