Cov ntaub ntawv sib sau ua ke thiab muab tub lim siv hauv cov tshuaj khib nyiab qhuav

Cov ntaub ntawv sib sau ua ke thiab muab tub lim yog cov khoom tseem ceeb ntawm cov tshuaj khib nyiab. Lawv tau ntxiv los muab lub zog, ruaj khov, thiab ua haujlwm tau zoo rau lub mortar, thiab tuaj yeem cuam tshuam cov khoom ntawm cov khoom kawg. Nov yog qee cov khoom siv sib sau ua ke thiab muab tso rau hauv cov tshuaj khib nyiab qhuav:

1. Xuab zeb: Xuab zeb yog cov khoom sib xyaw uas siv ntau tshaj plaws hauv cov tshuaj khib nyiab. Nws yog siv los ua cov ntaub ntawv tseem ceeb thiab muab cov khoom ntim ntawm cov tshuaj khib nyiab. Xuab zeb muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab qib, uas tuaj yeem cuam tshuam rau lub zog thiab kev ua haujlwm ntawm mortar.
2. Calcium carbonate: Calcium carbonate, tseem hu ua limestone, yog cov khoom siv feem ntau siv hauv cov tshuaj khib nyiab qhuav. Nws yog cov hmoov dawb uas tau ntxiv rau hauv mortar kom nws cov khoom ntom ntom thiab muab qee qhov ntxiv zog.
3. Fly ash: Fly tshauv yog cov khoom siv los ntawm kev hlawv cov thee thiab yog cov khoom siv ntxiv hauv cov khoom siv cement. Nws yog siv los ua cov khoom muab tub lim hauv cov tshuaj khib nyiab los muab lub zog thiab txo cov cement xav tau.
4. Perlite: Perlite yog ib qho khoom sib xyaw ua ke uas feem ntau siv hauv cov tshuaj khib nyiab qhuav. Nws yog tsim los ntawm volcanic iav thiab yog siv los txo qhov hnyav tag nrho ntawm mortar thiab muab cov khoom rwb thaiv tsev.
5. Vermiculite: Vermiculite yog lwm cov khoom sib xyaw ua ke uas siv rau hauv cov tshuaj khib nyiab qhuav. Nws yog tsim los ntawm tej yam ntuj tso minerals thiab yog siv los txhim kho lub workability ntawm lub mortar thiab txo nws qhov hnyav.
6. Cov hlaws iav: Cov hlaws iav yog me me, cov hlaws puag ncig ua los ntawm cov iav siv dua. Lawv tau siv los ua cov khoom siv sib sib zog nqus hauv cov tshuaj khib nyiab kom txo qhov hnyav tag nrho ntawm cov tshuaj khib thiab txhim kho nws cov khoom rwb thaiv tsev.
7. Silica fume: Silica fume yog cov khoom siv los ntawm kev tsim cov hlau silicon thiab yog cov hmoov zoo heev uas yog siv los ua cov khoom muab tub lim hauv cov tshuaj khib nyiab. Nws yog siv los ua kom lub zog thiab durability ntawm mortar thiab txo nws cov permeability.

Zuag qhia tag nrho, kev xaiv ntawm cov khoom sib sau ua ke thiab muab tub lim hauv cov tshuaj khib nyiab yog nyob ntawm qhov xav tau ntawm cov khoom kawg. Kev sib xyaw ua ke ntawm cov ntaub ntawv zoo tuaj yeem muab lub zog, ruaj khov, ua haujlwm tau zoo, thiab cov khoom siv rwb thaiv tsev uas xav tau rau ntau yam kev tsim kho.
