Dab tsi yog daim ntawv qhia rau qhuav pob mortar?

Dry pack mortar, tseem hu uaqhuav pob groutlos yog pob zeb qhuav, yog sib xyaw ntawm cov cement, xuab zeb, thiab cov ntsiab lus dej tsawg. Nws yog feem ntau siv rau cov ntawv thov xws li kho cov pob zeb ua vaj tse, teeb tsa cov kav dej da dej, lossis tsim cov plag tsev. Daim ntawv qhia rau qhuav pob mortar suav nrog kev faib ua feem ntawm cov khoom xyaw kom ntseeg tau qhov xav tau sib xws, ua haujlwm tau zoo, thiab lub zog. Txawm hais tias daim ntawv qhia meej yuav txawv nyob ntawm qhov yuav tsum tau ua thiab cov xwm txheej, ntawm no yog cov lus qhia dav dav rau kev npaj cov pob zeb qhuav:

Cov khoom xyaw:

1. Cement: Portland cement feem ntau yog siv rau cov pob zeb qhuav. Hom cement tuaj yeem sib txawv raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau ntawm qhov project. Ua raws li cov chaw tsim khoom cov lus pom zoo txog cov cement hom thiab qib.
2. Xuab zeb: Siv cov xuab zeb huv, zoo-qib uas tsis muaj impurities xws li av nplaum, silt, los yog organic teeb meem. Cov xuab zeb yuav tsum ua raws li cov qauv tsim nyog rau kev tsim kho.
3. Dej: Cov pob zeb qhuav yuav tsum muaj dej tsawg. Qhov sib piv ntawm cov dej-rau-mortar yuav tsum tau ua tib zoo tswj kom ua tiav qhov qhuav thiab tawv sib xws uas tuav nws cov duab thaum compacted.

Daim ntawv qhia:

1. Txiav txim siab qhov yuav tsum tau ntim ntawm cov pob zeb qhuav rau koj qhov project. Qhov no tuaj yeem suav tau raws li thaj chaw yuav tsum tau them thiab qhov xav tau thickness ntawm mortar txheej.
2. Mix Ratio: Feem ntau siv sib xyaw rau cov pob zeb qhuav yog 1 feem ntawm cov cement rau 3 lossis 4 seem xuab zeb los ntawm ntim. Qhov piv txwv no tuaj yeem hloov kho raws li qhov kev xav tau tshwj xeeb lossis raws li kev pom zoo los ntawm cov chaw tsim khoom. Nws yog ib qho tseem ceeb kom tswj tau qhov sib npaug sib npaug thoob plaws hauv txoj kev sib tov.
3. Kev sib xyaw ua ke:
   • Ntsuas qhov tsim nyog ntawm cov cement thiab xuab zeb raws li qhov xav tau sib tov sib piv. Nws raug nquahu kom siv lub thoob lossis lub thawv los ntsuas cov khoom xyaw kom raug.
   • Muab cov cement thiab xuab zeb tso rau hauv ib lub thawv sib xyaw kom huv los yog cov khoom sib tov sib xyaw. Sib tov ua ke kom huv si kom txog thaum lawv sib npaug. Koj tuaj yeem siv rab chais los yog cov cuab yeej sib xyaw kom ua tiav homogenous sib tov.
   • Maj mam ntxiv dej thaum txuas ntxiv mus. Ntxiv dej rau hauv me me increments thiab sib tov kom huv si tom qab txhua qhov ntxiv. Lub hom phiaj yog kom ua tiav qhov qhuav thiab tawv sib xws qhov twg lub mortar tuav nws cov duab thaum nyem hauv koj txhais tes.
4. Testing Consistency:
   • Txhawm rau kom lub mortar muaj qhov sib xws, ua ib qho kev sim slump. Nqa ib txhais tes ntawm cov mortar sib tov thiab nyem nws nruj nreem rau hauv koj txhais tes. Lub mortar yuav tsum khaws nws cov duab yam tsis muaj dej ntws tawm. Nws yuav tsum crumble thaum maj mam tapped.
5. Kev hloov kho:
   • Yog hais tias lub mortar qhuav dhau lawm thiab tsis tuav nws cov duab, maj mam ntxiv cov dej me me thaum sib tov kom txog thaum qhov kev xav tau ua tiav.
   • Yog tias lub mortar ntub dhau thiab poob nws cov duab yooj yim, ntxiv me me ntawm cov cement thiab xuab zeb nyob rau hauv qhov tseeb proportions kom ua tiav qhov xav tau sib xws.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias daim ntawv qhia rau cov pob zeb qhuav tuaj yeem sib txawv raws li cov kev xav tau tshwj xeeb, xws li lub peev xwm thauj khoom, kev ua haujlwm, lossis kev nyab xeeb. Nco ntsoov xa mus rau cov chaw tsim khoom cov lus qhia thiab cov lus qhia tshwj xeeb rau cov khoom siv khib nyiab qhuav uas koj siv, vim lawv tuaj yeem muab cov lus qhia tshwj xeeb thiab cov lus pom zoo rau kev sib xyaw ua ke thiab kev faib ua feem.

Ua raws li daim ntawv qhia thiab cov txheej txheem sib tov yuav pab xyuas kom meej tias cov pob zeb qhuav muaj qhov xav tau lub zog, ua haujlwm tau zoo, thiab ua haujlwm ntev rau koj daim ntawv thov kev tsim kho.
