Mortar vs Qhob
Mortar thiab pob zeb yog ob yam khoom siv feem ntau siv hauv kev tsim kho kev lag luam.Ob leeg yog tsim los ntawm cov cement, xuab zeb, thiab dej, tab sis cov proportions ntawm txhua yam sib txawv, muab txhua yam khoom nws tus yam ntxwv thiab kev siv.Hauv tsab xov xwm no, peb yuav tham txog qhov sib txawv ntawm mortar thiab pob zeb, lawv cov khoom, thiab lawv siv.
Mortaryog sib tov ntawm cement, xuab zeb, thiab dej.Nws yog feem ntau siv los ua cov khoom sib txuas ntawm cov cib, pob zeb, lossis lwm yam masonry units.Mortar yog cov khoom siv tsis muaj zog nrog lub zog compressive xws li 2.5 txog 10 N / mm2.Nws tsis yog tsim los nqa cov khoom hnyav, tab sis yog kom tuav cov masonry ua ke thiab muab qhov chaw du kom tiav.
Cov proportions ntawm cement, xuab zeb, thiab dej hauv mortar nyob ntawm daim ntawv thov thiab cov khoom xav tau.Piv txwv li, ib qho kev sib xyaw ua ke rau kev tso cov cib yog 1 feem ntawm cov cement rau 6 feem xuab zeb, thaum sib tov rau cov phab ntsa yog 1 feem cement rau 3 qhov xuab zeb.Ntxiv txiv qaub rau qhov sib tov tuaj yeem txhim kho kev ua haujlwm, durability, thiab dej tsis kam ntawm cov tshuaj khib.
Pob zeb, ntawm qhov tod tes, yog sib xyaw ntawm cov cement, xuab zeb, dej, thiab aggregates, xws li gravel lossis crushed pob zeb.Nws yog cov khoom siv muaj zog thiab ruaj khov nrog lub zog compressive xws li 15 txog 80 N / mm2, nyob ntawm qhov sib xyaw ua ke thiab qhov zoo ntawm cov khoom xyaw.Pob zeb yog siv rau ntau yam kev siv, xws li hauv paus, hauv pem teb, phab ntsa, kab teeb, kab, thiab txuas hniav.
Lub proportions ntawm cement, xuab zeb, dej, thiab aggregates nyob rau hauv pob zeb yog nyob ntawm daim ntawv thov thiab lub zog thiab durability.Ib qho kev sib xyaw ua ke rau kev tsim kho yog 1 feem ntawm cement rau 2 seem xuab zeb rau 3 qhov sib xyaw rau 0.5 feem dej, thaum sib xyaw rau cov pob zeb ntxiv yog 1 feem ntawm cov cement rau 1.5 feem xuab zeb mus rau 3 qhov sib xyaw rau 0.5 feem dej.Ntxiv admixtures, xws li plasticizers, accelerators, lossis air-entraining agents, tuaj yeem txhim kho kev ua haujlwm, lub zog, thiab kav ntev ntawm cov pob zeb.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm mortar thiab pob zeb yog lawv lub zog.Pob zeb muaj zog ntau dua li mortar, uas ua rau nws tsim nyog rau kev coj tus kheej hnyav thiab tiv thaiv compressive zog.Mortar, ntawm qhov tod tes, tsis muaj zog thiab hloov tau yooj yim, uas tso cai rau nws nqus tau qee qhov kev ntxhov siab uas cov chav tsev masonry ntsib vim qhov kub hloov pauv, ya raws nthuav dav, lossis kev txav ntawm cov qauv.
Lwm qhov txawv yog lawv txoj haujlwm ua haujlwm.Mortar yog yooj yim rau kev ua hauj lwm nrog ntau tshaj pob zeb, raws li nws muaj ib tug qis viscosity thiab yuav siv tau nrog ib tug trowel los yog ib tug taw tes.Mortar kuj teeb tsa qeeb dua li cov pob zeb, uas muab lub sijhawm rau cov mason ntau dua los kho qhov chaw ntawm cov masonry ua ntej lub mortar hardens.Cov pob zeb, ntawm qhov tod tes, yog qhov nyuaj rau kev ua haujlwm nrog, vim nws muaj viscosity ntau dua thiab yuav tsum tau siv cov cuab yeej tshwj xeeb, xws li cov twj tso kua mis lossis vibrators, yuav tsum tau muab tso rau thiab compacted kom zoo.Qhob kuj teem ceev tshaj li mortar, uas txwv lub sij hawm muaj rau kev kho.
Mortar thiab pob zeb kuj txawv ntawm lawv cov tsos.Mortar feem ntau yog xim sib dua li pob zeb, vim nws muaj cov cement tsawg dua thiab cov xuab zeb ntau dua.mortar kuj tuaj yeem ua xim nrog cov xim lossis cov xim kom phim cov xim ntawm cov masonry units lossis tsim cov teebmeem zoo nkauj.Qhob, ntawm qhov tod tes, feem ntau yog grey lossis dawb, tab sis kuj tuaj yeem ua xim nrog cov xim lossis cov stains kom ua tiav qhov tshwj xeeb.
Nyob rau hauv cov nqe lus ntawm tus nqi, mortar feem ntau pheej yig dua li pob zeb, vim nws yuav tsum tau tsawg cement thiab aggregates.Txawm li cas los xij, tus nqi ntawm kev ua haujlwm tuaj yeem sib txawv nyob ntawm qhov nyuaj thiab qhov loj ntawm qhov project, nrog rau kev muaj cov kws tshaj lij lossis cov neeg ua haujlwm ua vaj tse.
Tam sim no cia peb saib ze dua ntawm cov ntawv thov thiab siv cov tshuaj khib thiab pob zeb.Mortar feem ntau yog siv los ua cov khoom sib txuas ntawm cov masonry units, xws li cib, blocks, pob zeb, los yog vuas.Nws kuj yog siv los kho lossis patching cov masonry uas twb muaj lawm, nrog rau kev kho kom zoo nkauj, xws li taw tes, rendering, lossis plastering.Mortar tuaj yeem siv rau ob qho tib si sab hauv thiab sab nrauv, tab sis nws tsis haum rau kev tsim qauv lossis cov khoom hnyav.
Pob zeb, ntawm qhov tod tes, yog siv rau ntau yam kev siv, los ntawm cov phiaj xwm me me mus rau cov txheej txheem loj.Qee qhov kev siv ntawm cov pob zeb muaj xws li:
- Lub hauv paus: Pob zeb yog siv los tsim kom muaj qhov ruaj khov thiab theem hauv paus rau cov tsev, txuas hniav, lossis lwm yam qauv.Lub thickness thiab qhov tob ntawm lub hauv paus nyob ntawm seb cov av thiab qhov hnyav ntawm cov qauv.
- Pem teb: Cov pob zeb siv tau los tsim cov plag tsev ruaj khov thiab tsis tshua muaj kev tu vaj tse rau cov tsev nyob, kev lag luam, lossis kev lag luam.Nws tuaj yeem polished, stained, lossis stamped kom ua tiav qhov sib txawv.
- Phab ntsa: Cov pob zeb tuaj yeem muab pov rau hauv cov vaj huam sib luag precast lossis nchuav rau ntawm qhov chaw los tsim cov phab ntsa uas tsis muaj load-cov kabmob lossis cov kabmob tsis muaj kabmob.Nws kuj tseem siv tau rau khaws cov phab ntsa, suab barriers, lossis firewalls.
- Beams thiab txhua kab: Cov pob zeb tuaj yeem ntxiv dag zog nrog cov hlau tuav lossis cov fibers los tsim cov kab teeb thiab cov kab thiab kab rau kev txhawb nqa.Nws kuj tseem siv tau rau cov khoom precast, xws li ntaiv lossis balconies.
- Cov choj thiab txoj kev: Pob zeb yog cov khoom siv rau kev tsim cov choj, kev loj, thiab lwm yam kev thauj mus los.Nws tuaj yeem tiv taus cov khoom hnyav, huab cua hnyav, thiab hnav ntev ntev.
- Kho kom zoo nkauj ntsiab: pob zeb siv tau los tsim ntau yam khoom zoo nkauj, xws li sculptures, fountains, planters, lossis rooj zaum.Nws tuaj yeem ua xim lossis textured los ua rau lwm yam ntaub ntawv, xws li ntoo lossis pob zeb.
Hauv kev xaus, mortar thiab pob zeb yog ob yam khoom tseem ceeb hauv kev tsim kho, txhua tus muaj nws cov khoom tshwj xeeb thiab kev siv.Mortar yog cov khoom siv tsis muaj zog thiab hloov tau yooj yim siv rau kev sib koom ua ke ntawm cov masonry thiab muab kev ua tiav zoo, thaum lub pob zeb yog cov khoom siv muaj zog thiab nruj dua siv rau kev txhawb nqa thiab cov khoom hnyav.Kev nkag siab txog qhov sib txawv thiab kev siv ntawm mortar thiab pob zeb yuav pab tau architects, engineers, neeg cog lus, thiab cov tswv tsev txiav txim siab txog lawv cov kev tsim kho.
