Vim li cas cov dej ntawm cov masonry mortar tsis khaws cia siab dua qhov zoo dua?

Txawm hais tias kev khaws dej yog qhov tseem ceeb rau kev ua kom cov khoom siv cementitious noo thiab txhim kho kev ua haujlwm tau zoo, kev khaws dej ntau dhau hauv cov masonry mortar tuaj yeem ua rau muaj ntau yam tsis zoo. Nov yog vim li cas lub hauv paus ntsiab lus ntawm "qhov siab dua qhov khaws dej, qhov zoo dua" tsis muaj tseeb rau masonry mortar:

1. Lub Zog Txo: Yog tias dej khaws cia ntau dhau, cov cement uas nyob hauv cov mortar yuav yaj, ua rau cov cement tsawg dua ib qho ntim. Qhov no ua rau lub zog thiab kev ruaj khov ntawm cov mortar uas tau khov lawm txo qis, ua rau cov qauv ntawm cov masonry tsis zoo.
2. Kev Ntsws Ntau Ntxiv: Kev khaws dej ntau tuaj yeem ua rau lub sijhawm qhuav ntawm cov mortar ntev dua, ua rau kev ntsws ntev thiab ua rau muaj kev pheej hmoo ntawm kev tawg ntawm kev ntsws thaum ziab. Kev ntsws ntau dhau tuaj yeem ua rau lub zog sib txuas txo qis, kev nkag mus tau zoo dua, thiab txo qis kev tiv thaiv rau huab cua thiab cov yam ntxwv ib puag ncig.
3. Kev Nplaum Tsis Zoo: Cov pob zeb mortar uas muaj dej ntau dhau yuav ua rau muaj kev nplaum tsis zoo rau cov masonry units thiab cov substrate surfaces. Qhov muaj dej ntau dhau tuaj yeem cuam tshuam kev tsim cov bonds muaj zog ntawm cov mortar thiab cov masonry units, ua rau lub zog sib txuas tsawg dua thiab muaj kev pheej hmoo ntawm kev tshem tawm lossis delamination.
4. Lub Sijhawm Teeb Tsa Ncua: Cov dej khaws cia ntau tuaj yeem ua rau lub sijhawm teeb tsa ntawm cov xuab zeb ntev dua, ua rau cov khoom pib thiab kawg teeb tsa qeeb. Qhov kev ncua sij hawm no tuaj yeem cuam tshuam rau cov sijhawm tsim kho thiab ua rau muaj kev pheej hmoo ntawm cov xuab zeb ntxuav lossis tshem tawm thaum lub sijhawm teeb tsa.
5. Kev Muaj Peev Xwm Ntau Ntxiv Rau Kev Puas Tsuaj Los Ntawm Kev Khov-Thawj: Kev khaws dej ntau dhau tuaj yeem ua rau cov pob zeb masonry muaj kev puas tsuaj los ntawm kev khov-thaw. Qhov muaj dej ntau dhau hauv cov pob zeb mortar matrix tuaj yeem ua rau muaj dej khov ntau ntxiv thiab nthuav dav thaum lub sijhawm khov, ua rau muaj kev tawg me me, tawg, thiab puas tsuaj ntawm cov pob zeb.
6. Nyuaj rau Kev Tuav thiab Kev Siv: Cov pob zeb mortar uas khaws dej ntau dhau yuav ua rau muaj kev sagging, slumping, lossis ntws ntau dhau, ua rau nws nyuaj rau kev tuav thiab siv. Qhov no tuaj yeem ua rau kev ua haujlwm tsis zoo, cov pob qij txha tsis sib npaug, thiab kev zoo nkauj tsis zoo hauv kev tsim kho masonry.

thaum kev khaws dej yog qhov tsim nyog rau kev ua haujlwm tau zoo thiab ua kom cov khoom siv cementitious hauv masonry mortar txaus, kev khaws dej ntau dhau tuaj yeem muaj kev cuam tshuam tsis zoo rau kev ua haujlwm, kev ruaj khov, thiab kev ua haujlwm ntawm cov khoom. Kev sib npaug ntawm kev khaws dej nrog lwm yam khoom tseem ceeb xws li lub zog, kev nplaum, lub sijhawm teeb tsa, thiab kev tiv thaiv rau cov yam ntxwv ib puag ncig yog qhov tseem ceeb rau kev ua tiav kev ua tau zoo tshaj plaws thiab lub neej ntev hauv kev tsim kho masonry.
