Qhov kev nce ntxiv ntawm lub zog ntawm cov masonry mortar ua lub luag haujlwm dab tsi hauv cov khoom siv kho tshuab ntawm masonry?

Qhov kev nce ntxiv ntawm lub zog ntawm cov pob zeb masonry ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom siv kho tshuab ntawm cov qauv masonry. Cov pob zeb masonry ua haujlwm ua cov khoom siv khi uas tuav cov chav masonry (xws li cib, pob zeb, lossis cov pob zeb ua ke) ua ke los tsim cov phab ntsa, kem, arches, thiab lwm yam khoom siv. Cov khoom siv kho tshuab ntawm masonry, suav nrog nws lub zog, kev tawv, kev ruaj khov, thiab kev tiv taus ntau yam kev thauj khoom thiab cov xwm txheej ib puag ncig, nyob ntawm qhov zoo thiab kev ua tau zoo ntawm cov pob zeb siv. Nov yog li cas qhov kev nce ntxiv ntawm lub zog ntawm cov pob zeb pab txhawb rau cov khoom siv kho tshuab ntawm masonry:

1. Kev Ruaj Ntseg ntawm Cov Qauv:
   • Cov tshuaj mortar muaj zog heev ua rau cov qauv ruaj khov zoo dua rau cov masonry los ntawm kev ua kom muaj kev sib txuas ruaj khov thiab ruaj khov ntawm cov masonry sib txawv. Qhov no pab tiv thaiv kev sib cais, kev hloov chaw, lossis kev vau ntawm cov masonry hauv qab ntau yam kev thauj khoom, suav nrog cov khoom thauj tuag (qhov hnyav ntawm tus kheej), cov khoom thauj nyob (cov neeg nyob hauv), thiab cov khoom thauj ib puag ncig (cua, av qeeg).
2. Lub Peev Xwm Nqa Tau:
   • Qhov muaj zog ntxiv ntawm cov pob zeb masonry mortar ua rau nws tiv taus cov khoom hnyav dua, yog li ua rau muaj peev xwm nqa tau cov khoom hnyav ntawm cov qauv masonry. Qhov no tseem ceeb heev rau cov phab ntsa thiab cov kem uas nqa tau cov khoom hnyav, qhov twg cov pob zeb yuav tsum txhawb nqa cov khoom hnyav ntsug los ntawm cov qauv saum toj no thiab faib lawv mus rau lub hauv paus kom muaj kev nyab xeeb.
3. Lub Zog Flexural:
   • Cov mortar uas muaj zog dua pab txhawb kom muaj zog flexural hauv cov masonry assemblies, uas ua rau lawv tiv taus kev khoov lossis kev khoov thaum muaj kev thauj khoom sab nraud (xws li cua lossis av qeeg). Qhov no pab tiv thaiv kev tawg, kev tawg, lossis kev ua tsis tiav ntawm masonry thaum muaj kev thauj khoom dynamic lossis cyclic.
4. Kev Tiv Thaiv Kev Txiav:
   • Cov pob zeb mortar uas muaj zog dua ua rau cov pob zeb masonry tsis kam hloov pauv ntau, txo qhov yuav ua rau cov pob zeb masonry tsis ua haujlwm lossis swb ntawm cov pob zeb sib ze. Qhov no yog qhov tseem ceeb rau kev tswj hwm kev ruaj khov thiab kev ruaj khov ntawm cov phab ntsa masonry, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj av qeeg lossis cua hlob heev.
5. Kev ruaj khov thiab lub neej ntev:
   • Cov mortar uas muaj zog heev ua rau nws ruaj khov dua thiab tiv taus huab cua, dej nkag mus rau hauv, lub voj voog khov-yaj, thiab kev puas tsuaj ntawm cov tshuaj lom neeg. Qhov no ua rau cov qauv masonry siv tau ntev dua, txo qhov yuav tsum tau saib xyuas thiab ua kom nws ua haujlwm tau ntev hauv cov xwm txheej ib puag ncig hnyav.
6. Kev Sib Tw Nrog Cov Chav Masonry:
   • Cov khoom siv kho tshuab ntawm cov mortar yuav tsum sib xws nrog cov ntawm cov chav masonry kom ntseeg tau tias muaj kev faib tawm ntawm kev ntxhov siab sib npaug thiab txo qhov kev txav mus los lossis kev hloov pauv sib txawv. Kev sib phim lub zog thiab cov yam ntxwv ntawm mortar rau cov ntawm cov chav masonry pab ua kom zoo tshaj plaws kev ua tau zoo thiab kev ruaj khov ntawm kev sib dhos masonry.

Qhov kev nce ntxiv ntawm lub zog ntawm cov masonry mortar pab txhawb rau cov khoom siv kho tshuab thiab kev ua haujlwm ntawm cov qauv masonry. Los ntawm kev muab kev ruaj khov ntawm cov qauv, lub peev xwm thauj khoom, lub zog flexural, kev tiv thaiv shear, kev ruaj khov, thiab kev sib raug zoo nrog cov chav masonry, cov mortar muaj zog siab pab tsim cov kev tsim kho masonry muaj kev nyab xeeb dua, muaj zog dua, thiab siv tau ntev dua.
