Hoobiye-is-miidaamin ah ayaa badanaa loo isticmaalaa qurxinta sagxadda.Is-kala-qaadiddu waxay leedahay dareere wanaagsan, ma dillaacdo, ma godan, waxayna ilaalin kartaa sagxada.
Midabada waxaa ku jira sibidhka dabiiciga ah cawl, casaan, cagaar, iwm
Dhismuhu waa sahlan yahay, waxaa la isticmaali karaa ka dib marka lagu daro biyo iyo walaaq, waxaana si deg deg ah loogu faafi karaa dhulka si loo helo dabaq heer sare ah.

Halabuurka sibidhka is-beddelka ah
Sibidhka is-beddelka ah, oo sidoo kale loo yaqaan hoobiye is-beddelid, waa walxo isku dhafan oo biyo ah oo adag oo ka samaysan sibidhka oo ah walxaha aasaasiga ah oo si aad ah loogu daray walxo kale oo la beddelay.Hoobiyaha sibidhka ee hadda jira ee iskiis u siman ayaa leh qaabab kala duwan, laakiin ka kooban yahay waa isku mid.
Waxay inta badan ka kooban tahay lix qaybood:
1. Walxaha gelling isku qasan
Inta badan waxaa jira saddex nooc oo ah sibidhka aluminium sare, sibidhka Portland caadiga ah, iyo a-hemihydrate gypsum/anhydrite, oo xisaabiya 30%-40%.
2. buuxinta macdanta
Inta badan ciidda quartz iyo budada kaarbootka ee kaalshiyamka ah, oo u dhiganta 55%-68%.
3. Xakamaynta xinjirowga dhiigga
Inta badan dib-u-dejinta - tartaric acid, coagulant - lithium carbonate iyo superplasticizer - superplasticizer, xisaabinta 0.5%.
4. Rheology modifier
Inta badan foamers-ka iyo kuwa xasiliya, oo lagu xisaabiyo 0.5%.
5. Qaybaha la wanaajiyey
Inta badan budada polymer dib loo cusboonaysiin karo, oo u dhiganta 1%-4%.
6. Biyaha
Marka loo eego qaacidadu waxay u baahan tahay in lagu daro qadarka ku habboon ee biyaha si loo sameeyo hoobiye is-le'eg.

Shuruudaha waxqabadka ee hoobiye sibidhka is-miidaaminta
Hoobiyaha sibidhka ee is-miidaamiya ayaa leh shuruudo waxqabad gaar ah, oo ay ku jiraan dareeraha, xasilloonida slurry, xoogga cadaadiska, iwm.:
1. Dheecaannada: Guud ahaan, dareeraha ayaa ka weyn 210 ~ 260mm.
2. Degganaanshiyaha qulqulka: Ku shub dareeraha isku dhafan ee saxan quraarad ah oo lagu dhejiyay jihada toosan, oo u fiirso 20 daqiiqo ka dib.Waa in aanu jirin dhiig-bax cad, kala soocid, iyo xumbo.
3. Xoog cadaadis leh: Awoodda cadaadiska ee lakabka caadiga ah ee hoobiye sibidhka ayaa ka sarreeya 15MPa, iyo xoogga cadaadiska lakabka dusha sare ee sibidhka ayaa ka sarreeya 20MPa.
4. Xoog dabacsanaanta: Awoodda dabacsanaanta ee hoobiyeyaasha sibidhka ee is-miidaaminta warshaduhu waa inay ka weyn yihiin 6Mpa.
5. Waqtiga xinjirowga: Kadib markaad xaqiijiso in slurry-ku si siman loo walaaqay, hubi in isticmaalkiisu ka badan yahay 40 daqiiqo, shaqeyntuna ma saameyn doonto.
6. Saamaynta Saamaynta: Madaafiicda sibidhka ee is-hoosaysiiya waa in ay u adkaysan karaan isku dhaca jidhka bini'aadamka iyo walxaha la raro ee gaadiidka caadiga ah, iyo saamaynta iska caabbinta dhulku waxay ka badan tahay ama la mid tahay 4 joules.
7. Ku-xidhka xoogga cufan ee lakabka aasaasiga ah: Awoodda xajinta ee walxaha is-beddelka ah ee dabaqa sibidhka ayaa badanaa ka sarreeya 0.8 MPa.
Astaamaha hoobiyeyaasha is-milliminta:
1. Waxay leedahay dareere wanaagsan, si siman ayay u faaftaa, waxayna si fiican ugu qulquli kartaa daldaloolada tuubooyinka kululaynta sagxadda.
2. Hoobiyeyaasha adag ee is-le'egta ayaa si siman loo qaybiyay waxayna leeyihiin awood wanaagsan oo ka hortagga kala-soocidda.
3. Qaab dhismeedka cufan ee hoobiyeyaasha is-beddelka ah ayaa ku habboon kor u qaadista kuleylka, taas oo xaqiijin karta saameynta kulaylka si fiican.
4. Xoog sare, adkeysi degdeg ah, badanaa 1-2 maalmood ayaa la isticmaali karaa.
5. Heerarka hoos u dhaca ayaa ah mid aad u hooseeya, mana fududa in la dildilaaciyo, la nadiifiyo oo bannaan.
Isticmaalka hoobiyeyaasha is-beddelka:
Hoobiyeyaasha is-beddelka ah ayaa inta badan loo isticmaalaa qurxinta sagxadda dhismayaasha casriga ah.Waxay leedahay sifooyin fidsan sare, dheecaan wanaagsan oo aan dillaacin, waxaana si qoto dheer u jecel inta badan milkiilayaasha.
Dabaqa is-hoosaysigu waa mid aan sinaba u wada jirin, is-barbardhig, dhulku waa siman yahay, siman oo qurux badan;boodhka celin, biyuhu, fududahay in la nadiifiyo;iska caabin daxalka wanaagsan, caabbinta acid iyo alkali, xidho caabbinta, cadaadis cadaadis, caabbinta saamaynta, iyo barti gaar ah.
Isticmaalka iyo xaaladaha codsiga:
