1. Xaaladda hadda jirta ee isticmaalka kheyraadka ee birta wasakhda ah:

Budada birta ah ee slag ayaa muddo dheer lagu daray heerka qaranka sida isku darka sibidhka. Tiro badan oo tijaabooyin isbarbardhig ah ayaa caddeeyay in: Marka aagga dusha sare ee budada slag-ka birta ah uu ka badan yahay 420m2/kg, waxqabadkeedu wuxuu la mid yahay slag-ka foornada qaraxa. Isku darka isku-dhafka ah ee budada slag-ka birta ah iyo budada slag-ka ma aha oo kaliya inay sii wanaajin karto saamiga budada slag-ka birta ah ee budada isku-dhafka ah, laakiin sidoo kale waxay kordhin kartaa xaddiga beddelka budada isku-dhafka ah ee sibidhka iyadoo lagu saleynayo hubinta waxqabadka shubka, si loo sii yareeyo kharashka diyaarinta shubka. Waxay si cad u yarayn kartaa isbeddelka yaraanta ee xidhmada waxayna hagaajin kartaa iska caabinta dildilaaca ee xidhmada. Tani waxay muujinaysaa in alaabada budada slag-ka birta ah ay leeyihiin rajo suuq oo wanaagsan. Waqtigan xaadirka ah, xasilloonida mugga ee slag-ka birta ah ayaa hoos u dhacda sababtoo ah jiritaanka CaO2 iyo MgO2 xor ah. Waxyaabaha sare ee oksaydhka birta ah waxay kordhisaa dhibka shiididda, isticmaalka awoodda sare ee budada slag-ka tan, iyo dhibka farsamaynta budada slag-ka birta ah. Sidaa darteed, mugga iibka ee suuqa budada birta ah waa yar yahay, taas oo sidoo kale ka dhigaysa budada birta ah inay noqoto suuq soo koraya oo la horumarinayo.

2. Isku darka shubka wuxuu siinayaa meel loogu talagalay isticmaalka shiididda birta dhuuban ee aadka u fiican:

Isku-darka isku-dhafka ah ee konkriitka ee dhexe waa isbeddel weyn oo ku yimid qaabka wax-soo-saarka mashaariicda dhismaha, saamiga codsiyada konkriitka ee diyaarsan ayaa calaamad u ah heerka wax-soo-saarka warshadaha konkriitka ee dalka. Ku-dhaqanku wuxuu muujinayaa in isticmaalka konkriitka diyaarsan uu kordhin karo wax-soo-saarka shaqada in ka badan labanlaab, badbaadin karo sibidhka 10% ~ 15%, yareyn karo kharashyada mashruuca qiyaastii 5%, wuxuuna hubin karaa tayada mashruuca, badbaadin karaa dhulka dhismaha, yareyn karaa wasakhowga boodhka, si loo gaaro dhisme cagaaran. Horumarinta konkriitka ganacsiga waxay kor u qaaddaa horumarinta wax-soo-saarka budada konkriitka waxayna ballaarisaa suuqa baahida budada konkriitka. Warshadda isku-darka konkriitka ee diyaarsan ee Shiinaha waxaa la aasaasay 1980-meeyadii, markii hore Shanghai, Jiangsu iyo meelo kale, sababtoo ah ballaarinta joogtada ah ee baaxadda dhismaha, gaar ahaan horumarka degdegga ah ee dhismaha magaalooyinka xeebta koonfur-bari, oo ay weheliso taxane siyaasado iyo tallaabooyin taageero ah oo ay qaadeen mas'uuliyiinta dhismaha, si konkriitka diyaarsan ee magaaladu uu u kordho 15% sannadkii. Maadaama qiimaha slag iyo slag birtu uu ka hooseeyo kan sibidhka, shubka lagu qasay slag iyo slag birtu waa mid dhaqaale ahaan ku habboon in loo isticmaalo shubka ganacsiga ee aadka isugu dhafan. Shubka lagu sameeyay isku darka slag iyo slag birta iyo sibidhka, dhagaxa iyo ciidda jaalaha ah wuxuu leeyahay faa'iidooyinka xoog sare oo dambe, kulayl yar oo fuuq-celin ah, iska caabin wanaagsan oo xirasho iyo xoog sare oo isku xidhka birta ah. Waxay si gaar ah ugu habboon tahay dhismayaasha dhaadheer, DAMS-yada, garoomada diyaaradaha, aasaaska qoto dheer ee waaweyn iyo mashaariicda biyaha hoostooda. Waqtigan xaadirka ah, shubka xoogga badan waxaa inta badan lagu diyaariyaa isku darka dambaska silica iyo wakiilka yareynta biyaha ee waxtarka sare leh, laakiin la'aanta ash silica ceeriin iyo wakiilka yareynta biyaha ee waxtarka sare leh waa qaali, taasoo keentay kharash sare oo shubka ah. Iyadoo shuruudaha sare iyo sare ee sifooyinka shubka ee mashaariicda gaarka ah ee baaxadda weyn, baahida sii kordheysa ee shubka ganacsiga ayaa furtay suuq ballaaran oo loogu talagalay isticmaalka ballaaran ee budada slag iyo birta. Fahmidda dadku ee sifooyinka budada slag iyo birta, oo ah agab dhisme oo cusub, ayaa sidoo kale sii qoto dheereysa. Iyada oo la horumarinayo lana adeegsanayo shubka ganacsiga ee dalka iyo hirgelinta heerarka qaranka ee la xiriira wax soo saarka budada shubka iyo birta, iyo hirgelinta siyaasadaha sida mamnuucidda isku darka shubka goobaha dhismaha ee magaalooyinka, suuqa budada shubka iyo birta ayaa sii kordhaya, isticmaalkeeduna wuxuu soo jiidan doonaa dareen badan.

3. Habka diyaarinta iyo qalabka birta lagu shiido ee toosan ee budada yar yar ayaa la caan baxay oo la mariyey

Waqtigan xaadirka ah, tiknoolajiyada shiididda toosan waxaa loo isticmaalaa in lagu shiido budada birta ee slag micro-budada iyo in la soo saaro alaabada beddesha clinker-ka sibidhka ee tamarta sare leh, kaas oo ka tirsan tiknoolajiyada wax soo saarka ee horumarsan ee warshadaha. Waagii hore, badanaa slag, slag bir ah iyo clinker sibidhka, gypsum, iwm. oo isku wada jira, iyadoo la raacayo qayb gaar ah oo shiididda wax soo saarka shiididda sibidhka. Sababtoo ah awoodda liidata ee slag iyo slag birta, shiididda si fiican looma shiidi karo marka lagu qaso clinker sibidhka, waxqabadkeeda si buuxda looma horumarin karo, tirada iyo codsiga slag iyo slag birtana waxay ku kooban yihiin ilaa xad. Diyaarinta budada ultrafine ee ka timaadda slag birta oo keliya, shirkadaha birta iyo birta ee Jiangsu ayaa safka hore kaga jira. Dhowr shirkadood oo bir ah oo ay matalaan Changzhou Zhongtian Iron and Steel ayaa dhisay khadadka wax soo saarka slag toosan ee birta ee slag. Maadaama ay tahay soo saaraha warshadda toosan ee slag micro-budada birta, HCM Machinery waxay bixisaa taageero farsamo oo ku saabsan habka shiididda slag birta ee ultrafine iyo wax soo saarka qalabka warshadda toosan ee muhiimka ah. Astaamaha farsamo ee ay leedahay waxaa ugu muhiimsan dhinacyada soo socda: xulashada budada birta ee shiididda toosan, oo leh tignoolajiyada horumarsan, wax soo saar la isku halleyn karo, astaamaha wax soo saarka shaqada oo sarreeya, oo leh warshad toosan si loo soo saaro tan oo ah dhul gaar ah oo ah 400m2/kg ~ 500m2/kg slag, budada birta ee slag, marka loo eego wax soo saarka warshadaha kubbadda ee caadiga ah ee isku miisaanka korontada badbaadinta budada 30% ~ 50%; Budada wanaagsan ee slag iyo birta ayaa si toos ah loogu daraa shubka, taas oo badbaadisa xaddiga sibidhka sidaas darteedna badbaadisa isticmaalka tamarta ee wax soo saarka sibidhka. Slag, habka shiididda slag birta, ayaa si dabacsan u hagaajin kara tayada alaabta iyadoo loo eegayo baahiyaha suuqa. Iyadoo la kordhinayo ku darista slag iyo birta ee slag ee shubka, kulaylka fuuq-baxa iyo waxa ku jira qaybaha waxyeelada leh ee shubka ayaa la dhimi karaa, taas oo abuurta xaalado wanaagsan oo lagu hagaajinayo waxqabadka shubka iyadoo la isticmaalayo tamar yar. Slag birta waxaa lagu shiidi karaa budada shiididda toosan, agabkana waxaa lagu shiidi karaa jawi qoyan heerkul sare (100℃ ~ 300℃). Inta badan kaalshiyamka oksaydhka bilaashka ah iyo magnesium oksaydhka bilaashka ah ee ku jira budada birta ee slag micro-powder ayaa lagu qoyaa kaalshiyamka hydroxide iyo magnesium hydroxide oo aad u firfircoon. Intaa waxaa dheer, sababtoo ah ku darista slag iyo birta slag ee shubka, falcelinta alkali ee isku-darka ayaa si wax ku ool ah loo dhimi karaa, dildilaaca yar yar ee shubka waa laga hortagi karaa, cimriga dhismayaashana waa la dheereyn karaa. Sidaa darteed, shubka lagu qasay budada slag waxaa soo dhaweynaya warshadaha dhismaha sababtoo ah sifooyinkeeda gaarka ah. Shiidida slag birta kaliya waxaa loo isticmaali karaa badeecad wax soo saar iyo isku-darka shubka iyadoo loo eegayo baahiyaha suuqa, waxaana sidoo kale lagu hagaajin karaa iyadoo loo eegayo baahida loo qabo in la hagaajiyo tayada iyo isku-darka si loogu habeeyo sibidhka iibka ah.
