mortar dav siv yog plastering mortar, tawg resistant mortar thiab masonry mortar.Lawv qhov sib txawv yog raws li nram no:
Crack resistant mortar:
Nws yog ib lub mortar ua los ntawm cov tshuaj tiv thaiv tawg ua los ntawm cov tshuaj pleev xim polymer thiab cov khoom sib xyaw, cov cement thiab xuab zeb hauv ib qho kev faib ua feem, uas tuaj yeem ua tau raws li qee qhov deformation thiab tswj tsis muaj kev tawg.
Cov khib nyiab resistant yog cov khoom tiav, uas tuaj yeem siv los ntawm kev ntxiv dej thiab sib tov ncaj qha.Cov khoom tiav los tiv thaiv tawg mortar yog cov xuab zeb zoo, cov cement thiab cov tshuaj tiv thaiv tawg.Cov khoom tseem ceeb ntawm tus neeg sawv cev tiv thaiv kab mob yog ib hom silica fume, uas tuaj yeem sau cov pores ntawm cov cement hais, tsim cov gels nrog cov khoom hydration, thiab hnov mob nrog alkaline magnesium oxide los ua gels.
Plastering mortar:
Cov mortar siv rau saum npoo ntawm cov tsev thiab cov khoom siv thiab cov khoom siv hauv paus, uas tuaj yeem tiv thaiv lub hauv paus chav kawm thiab ua tau raws li kev siv, tuaj yeem raug hu ua plastering mortar (tseem hu ua plastering mortar).
Mortar masonry:
Ib qho ntxiv rau lub tsev stacking uas muaj cov khoom siv gel (feem ntau yog cov cement thiab txiv qaub) thiab nplua aggregate (feem ntau yog ntuj zoo xuab zeb).
Kev tuav dej ntawm mortar yog hais txog lub peev xwm ntawm mortar los khaws dej.Cov khib nyiab nrog cov dej tuav tsis zoo yog qhov ua rau los ntshav thiab sib cais thaum thauj thiab khaws cia, uas yog, cov dej ntab saum toj no thiab cov xuab zeb thiab cov cement hauv qab.Nws yuav tsum tau muab sib xyaw ua ntej siv.
Txhua yam kev kawm hauv paus xav tau kev tsim kho mortar muaj qee yam kev nqus dej.Yog hais tias cov dej tuav ntawm mortar tsis zoo, nyob rau hauv tus txheej txheem ntawm mortar txheej, tsuav yog npaj txhij tov mortar tiv tauj nrog lub thaiv los yog hauv paus chav kawm, cov dej yuav absorbed los ntawm cov npaj tov mortar.Nyob rau tib lub sijhawm, cov dej yuav evaporate los ntawm qhov chaw ntawm mortar, uas ua rau cov dej tsis txaus rau mortar vim dej poob, cuam tshuam rau cov dej ntxiv ntawm cov cement, cuam tshuam rau kev loj hlob ntawm mortar lub zog, uas ua rau muaj zog tshwj xeeb, lub zog sib cuam tshuam ntawm mortar hardened lub cev thiab lub hauv paus ua qis, uas ua rau mortar cracking thiab ntog tawm.Rau cov mortar nrog cov dej tuav zoo, cov cement hydration yog qhov txaus, lub zog tuaj yeem txhim kho ib txwm, thiab nws tuaj yeem sib raug zoo nrog lub hauv paus chav kawm.
Yog li ntawd, ua kom cov dej tuav ntawm mortar tsis yog tsuas yog ua rau kev tsim kho, tab sis kuj nce lub zog.
