Dab tsi yog qhov yuav tsum tau ua ntawm cov cement mortar?

Cov kev cai yooj yim rau cov pob zeb masonry yog qhov tseem ceeb los xyuas kom meej qhov kev ua tau zoo, ua haujlwm ntev, thiab kev ncaj ncees ntawm kev tsim cov masonry.Cov kev xav tau no yog txiav txim siab raws li ntau yam xws li hom masonry units, kev tsim kho, kev xav txog kev tsim qauv, ib puag ncig, thiab kev nyiam zoo nkauj.Ntawm no yog cov ntsiab lus tseem ceeb rau kev tsim cov mortar:

1. Compatibility nrog Masonry Units:
   • Lub mortar yuav tsum sib haum nrog hom, qhov loj me, thiab cov khoom ntawm cov masonry units uas siv (xws li cib, blocks, pob zeb).Nws yuav tsum muab kev sib raug zoo thiab kev txhawb nqa rau cov masonry units, kom ntseeg tau tias muaj kev ntxhov siab tsis sib xws thiab txo qis qhov sib txawv txav los yog deformation.
2. Muaj zog txaus:
   • Lub mortar yuav tsum muaj lub zog txaus compressive los txhawb cov ntsug thiab sab loads rau ntawm lub masonry qauv.Lub zog ntawm mortar yuav tsum tsim nyog rau daim ntawv thov thiab cov qauv tsim, raws li kev txiav txim siab los ntawm engineering suav thiab cov qauv tsim tshwj xeeb.
3. Ua haujlwm tau zoo:
   • Lub mortar yuav tsum muaj kev ua haujlwm zoo, tso cai rau kev sib xyaw yooj yim, thov, thiab sib kis thaum tsim kho.Nws yuav tsum yog cov yas thiab cohesive txaus kom ua raws li cov masonry units thiab tsim cov pob qij txha zoo ib yam, thaum tseem ua teb rau cov cuab yeej thiab cov txheej txheem tiav.
4. Kev sib raug zoo thiab kev sib raug zoo:
   • Qhov sib xws ntawm cov mortar yuav tsum tsim nyog rau txoj kev tsim kho thiab hom masonry units.Nws yuav tsum muaj cov cohesion txaus thiab nplaum lub zog kom muaj kev ncaj ncees ntawm cov pob qij txha thiab tiv thaiv sagging, slumping, los yog ntws thaum lub sij hawm installation.
5. Kev tuav dej kom txaus:
   • Lub mortar yuav tsum khaws cov dej kom zoo los xyuas kom meej hydration ntawm cov ntaub ntawv cementitious thiab ua kom lub sijhawm ua haujlwm ntawm cov tshuaj khib thaum siv.Kev tuav dej kom txaus pab tiv thaiv kom qhuav ntxov ntxov thiab txhim kho kev sib raug zoo, adhesion, thiab kho cov yam ntxwv.
6. Durability thiab huab cua Resistance:
   • Lub mortar yuav tsum ruaj thiab resistant rau ib puag ncig yam xws li ya raws, kub hloov pauv, khov-thaw mus, tshuaj raug, thiab UV hluav taws xob.Nws yuav tsum tswj hwm nws cov qauv kev ncaj ncees, zoo li, thiab kev ua tau zoo nyob rau lub sijhawm raws li cov kev pabcuam qub thiab xav tau.
7. Tsawg Shrinkage thiab Cracking:
   • Lub mortar yuav tsum muaj qhov tsawg kawg nkaus shrinkage thiab tawg thaum ziab thiab kho kom tsis txhob cuam tshuam qhov kev ruaj ntseg thiab kev zoo nkauj ntawm kev tsim kho masonry.Kev faib ua kom zoo, sib tov, thiab kho cov kev coj ua tuaj yeem pab txo qis qis thiab tawg hauv cov tshuaj khib nyiab.
8. Uniform Xim thiab tsos:
   • Lub mortar yuav tsum muab cov xim sib xws thiab cov tsos uas ua kom tiav cov chav tsev masonry thiab ua tau raws li qhov xav tau ntawm qhov project.Cov xim sib xws, kev ntxhib los mos, thiab ua tiav pab txhim kho qhov pom kev pom thiab tag nrho qhov zoo ntawm kev tsim kho masonry.
9. Ua raws li Cov Qauv thiab Cov Cai:
   • Lub mortar yuav tsum ua raws li cov cai hauv tsev, cov qauv, thiab cov kev qhia tshwj xeeb uas tswj xyuas kev tsim vaj tse hauv koj cheeb tsam.Nws yuav tsum ua kom tau raws li qhov xav tau yam tsawg kawg nkaus rau cov khoom muaj pes tsawg leeg, kev ua tau zoo, thiab kev tswj kom zoo.

Los ntawm kev ua kom cov masonry mortar ua tau raws li cov kev cai yooj yim no, cov neeg tsim khoom, cov neeg cog lus, thiab cov neeg tsim qauv tuaj yeem ua tiav kev ua tiav, ruaj khov, thiab ua kom zoo nkauj ua kom zoo nkauj uas ua tau raws li qhov xav tau ntawm qhov project thiab tiv taus qhov kev sim ntawm lub sijhawm.
