Cabbirka qeexida iyo sifooyinka mesh silig ayaa la soo bandhigay

Horraantii 1940-kii,sibidhka meshwaxa la bilaabay in loo isticmaalo warshadaha samaynta maraakiibta.Waqtigan xaadirka ah, looma isticmaalo oo keliya dhisidda maraakiibta, laakiin sidoo kale walaac ballaadhan.Waxaa si fiican loo og yahay in kalsiyum oxide bilaashka ah ee clinker sibidhka ay saameyn ku yeelato xasilloonida, sababtoo ah kalsiyum oxide ee bilaashka ah wuxuu bilaabaa inuu fuuqbaxo ka dib qallafsanaanta sibidhka, mugga bilyankiisa biyaha (calcium hydroxide) si loo kordhiyo 1.5 ~ 2.0 jeer, si ay sibidhka adkaynaya jidhka oo dilaacay, taasoo keentay xasiloonida shabidhka oo liidata.

Sidaa darteed, waxaa loo tixgelin karaa in haddii calcium oxide lacag la'aan ah in cement adag tahay mustaqbalka fuuq-la'aanta, ka dibna ma keeni doono dhibaatada xasiloonida cement liidata.Xogta laxiriirta waxay muujineysaa in saameynta kalsiyum oxide ee bilaashka ah ee dambaska foornada ay ku leedahay xasilloonida ay aad uga fudud tahay tan kalsiyum oxide ee bilaashka ah ee clinker.Waxaa la arki karaa in heerka fuuq-baxa ee labada nooc ee calcium oxide ee bilaashka ah uu ka duwan yahay.Heerka fuuq-baxa ee kalsiyum oxide ee bilaashka ah ee ku jira dambaska foornada waa dhakhso.Mid ka mid ah sababaha ayaa ah in kulaylka dambaska foornada uu ka hooseeyo kan clinker-ka iyo dambaska foornada uu ku jiro xaaladda iftiinka iftiinka.Kaalshiyam oxide-ka iftiinka gubanaya way fududahay in la fuuqeeyo marka loo eego heerkulka sare ee calcined calcium oxide.
Xirashadu way ku yar tahay xaaladda la duubay.Waxa ku jira kalsiyum oxide ee bilaashka ah ee ku jira dambaska kiln waa sarreeyaa, wayna fududahay in la fuuqeeyo si loo soo saaro kalsiyum hydroxide oo leh cufnaan gaar ah oo yar, kaas oo sidoo kale saameeya saamaynta roobka ee wareegga biyaha.Waxaa loo isticmaalaa in injineernimada dhismaha, injineernimada haydarooliga, qaab dhismeedka alaabta iyo mesh silig waa ~ ka mid ah ka kooban yahay birta mesh shamiitada, waa wax adkeysiga xoojiyey, qaybinta lebis ee alaabta jajaban (hoobiye sibidhka), Taiwan iyada oo hoobiye cement , Xoogga marka qallafsanaanta wadajirka ah, oo leh saameyn isku mid ah, waxay si buuxda u ciyaaraan sifooyinka walxaha isku dhafan, Dhowr nooc oo isku dhafan oo leh sifooyin aad u fiican ayaa la sameeyay.
