Tus yuam sij kom ntseeg tau qhov tseeb ntawm cov cement mortar mix proportions yog nyob rau hauv nruj tswj kev ntsuas cov khoom raw, standardizing tus txheej txheem sib tov, thiab siv tag nrho - txheej txheem kev soj ntsuam zoo. Deviations nyob rau hauv txhua kauj ruam yuav cuam tshuam mortar zog thiab kev tsim kho zoo.
Kev Ntsuas Raw Khoom Zoo: Txhua yam khoom yuav tsum raug ntsuas. Automated mixing nroj tsuag raug pom zoo vim lawv cov metering ntau dua. Kev tso cai yuam kev: ± 1% rau cov cement, dej, thiab cov khoom sib xyaw; ± 2% rau xuab zeb. Cov khoom siv hnyav yuav tsum tau ntsuas ua ntej kev tsim kho kom tsis txhob muaj qhov sib txawv ntawm cov khoom siv tsis raug.
Standardized Material Addition Sequence and Mixing Time: Cov khoom sib txuas ntxiv yuav tsum yog: xuab zeb → cement → qhuav sib tov kom huv si → ntxiv dej thiab sib tov. Yog tias siv cov khoom sib xyaw, cov hmoov sib tov yuav tsum tau ntxiv ua ke nrog cov cement; kua admixtures yuav tsum yaj nyob rau hauv dej thiab ntxiv. Lub sijhawm sib xyaw tag nrho yuav tsum tsis pub tsawg dua 90 vib nas this kom ntseeg tau tias sib xyaw ua ke; Thaum cov khoom sib xyaw ntxiv, qhov no yuav tsum tau txuas mus rau tsawg kawg 120 vib nas this.
Siv Cov Khoom Sib Nqus Sib Nqus Cov Ntawv Sau thiab Kev Saib Xyuas Tshwj Xeeb: Teeb tsa cov ntawv sib xyaw ua ke ntawm qhov chaw tsim kho, qhia meej meej cov cement, xuab zeb, thiab dej kom muaj nuj nqis rau txhua pawg. Muab cov neeg ua haujlwm tshwj xeeb los saib xyuas cov txheej txheem pub khoom noj kom tiv thaiv tib neeg kev ua yuam kev lossis kev hloov kho tsis raug rau qhov sib npaug.
Ua Kev Sib Tw Sib Tw Sib Tw thiab Kev Kho Kom Zoo Dua: Ua kev sim sib xyaw ua ntej kev tsim kho. Kho cov dej thiab xuab zeb sib piv raws li qhov tseeb tsis xws li cov xuab zeb noo noo, qhov loj me, thiab qib cement kom ua haujlwm tau zoo thiab muaj zog raws li cov qauv. Zoo- kho cov dej- cement piv tam sim ntawd thaum huab cua hloov pauv (xws li, kub thiab qhuav) kom tsis txhob muaj dej ntau dhau ntawm cov tshuaj khib nyiab.
Txhim khu kev soj ntsuam thaum lub sij hawm tsim kho: Ua yam tsawg kawg yog ob qhov kev ntsuam xyuas slump ib zaug los ntsuam xyuas seb lub mortar lub fluidity ua tau raws li qhov yuav tsum tau ua. Ib txhij saib nws cohesiveness thiab tuav dej; tam sim ntawd tsis txhob siv cov tshuaj khib thiab tshawb xyuas qhov ua rau yog tias pom muaj qhov txawv txav.
