Xaiv lub pob zeb zoo tshaj plaws rau Tombstones hauv huab cua txias

Thaum xaiv cov pob zeb tombstones rau cov cheeb tsam uas muaj lub caij ntuj no hnyav, Frost, thiab khov -thaw cycles, cov khoom xaiv yog qhov tseem ceeb. Cov pob zeb uas ua tau zoo nyob rau hauv cov huab cua nruab nrab tuaj yeem tawg, tawg, lossis tsis muaj xim nyob rau hauv qhov txias txias, ua rau muaj teeb meem zoo nkauj thiab cov qauv. Kev nkag siab txog cov khoom uas ua rau muaj kev ruaj khov-xws li qhov ntom ntom, porosity, thiab tsis kam rau kev nqus dej- yog qhov tseem ceeb rau cov neeg muag khoom thiab cov neeg yuav khoom npaj cov phiaj xwm hauv huab cua txias.

Phau ntawv qhia no tshawb txog cov ntsiab lus tseem ceeb los txiav txim siab thaum xaiv cov khoom tombstone rau thaj chaw txias.

Nyob rau hauv huab cua txias, tombstones tas li raug mus rau lub voj voog ntawm khov thiab thawing. Pob zeb nrog siabnqus dejlos yog tsis tshua muaj qauv kev ncaj ncees yog feem ntau tawg los yog delamination.

Cov khoom zoo tagnrho:Tsawg porosity, siab compressive zog, thiab tsawg kawg micro- tawg

Common resilient pob zeb:Granite yog nyiam vim nws cov qauv nruj crystalline, tsis tshua muaj dej nqus, thiab ntuj te kuj

Zam:Cov pob zeb mos los yog cov pob zeb uas muaj qhov ntxeem tau zoo xws li qee qhov marbles lossis limestone uas tuaj yeem nqus dej thiab deteriorate sij hawm

Cov neeg muag khoom yuav tsum pom zoo cov pob zeb uas tau sim raukhov-thaw kev ua haujlwmnyob rau hauv cov huab cua zoo sib xws.

Pob zeb ntom ntom ncaj qha cuam tshuam rau nws lub peev xwm los tiv thaiv kev ntxhov siab thiab kev cuam tshuam ib puag ncig.

• Siab - pob zeb ceevmuab kev tiv thaiv ntau dua rau kev tawg hauv qab khov -thaw cycles
• Nthuav granite ntau yam yog tshwj xeeb tshaj yog haum rau upright monuments thiab hnyav tombstones
• Tsawg- pob zeb ceev tuaj yeem tawg lossis nti yooj yim dua thaum thauj, teeb tsa, lossis huab cua

Rau loj lossis ornate tombstones, xaiv antom, structurally robust pob zebua kom ruaj ntseg ntev -lub sij hawm.

Covtus nqi nqus dejntawm lub pob zeb yog ib qho tseem ceeb tshaj plaws qhia txog nws qhov haum rau cov huab cua txias.

• Pob zeb nrog nqus<0.5% are generally frost-resistant
• Cov pob zeb nqus dej siab tuaj yeem ntes dej, uas nthuav dav thaum khov thiab ua rau micro- tawg
• Nto tiav kuj tseem ceeb: polished thiab honed finishes txo dej nkag mus rau piv nrog ntxhib nto

Xyuas kom tsis muaj dej nqus tsis tau tsuas yog tiv thaiv kev tawg tab sis tseem khaws cov ntawv sau thiab cov khoom zoo nkauj.

 

Txawm tias cov pob zeb ruaj khov tuaj yeem ua rau muaj kev puas tsuaj yog tias ib puag ncig yam tsis quav ntsej:

• Kev tawg thiab tawgvim khov -thaw cycles
• Spalling los yog flakinglos ntawm dej nkag mus rau hauv cov pob zeb ntxeem tau
• Faded inscriptionsyog hais tias qhov chaw ncaj ncees yog cuam tshuam los ntawm Frost
• Kev tsis sib haum xeebthaum lub hauv paus kev txhawb nqa tsis txaus ntawm cov av khov

Xaiv lub pob zeb zoo thiab txhim kho lub hauv paus tsim nyog yuav pab txo qis cov kev pheej hmoo no.

• Granite:Feem ntau siv rau cov cheeb tsam txias; zoo heev Frost tsis kam thiab tsis tshua muaj txij nkawm
• Quartzite:Nthuav thiab ruaj khov, txawm tias tsawg dua; resistant rau khov
• Tsis txhob softer marbles thiab limestonetshwj tsis yog tias kho tau zoo thiab chaw nyob

Thaum muab tombstones rau kev lag luam thoob ntiaj teb, kev nkag siab txog kev nyab xeeb hauv cheeb tsam ua kom cov ntaub ntawv ua tau zoo raws li cov neeg xav tau.

Xaiv lub qhov ntxa rau cov huab cua txias yuav tsum tau ua tib zoo ntsuam xyuas ntawm Frost tsis kam, ntom, nqus dej, thiab cov ntaub ntawv keeb kwm ntev. Granite tseem yog cov khoom nyiam rau nws cov kev sib xyaw ua ke ntawm lub zog, porosity tsawg, thiab ntev - huab cua kev ua haujlwm ntev. Los ntawm kev xaiv cov pob zeb ruaj khov thiab xav txog lub hauv paus thiab kev teeb tsa, cov neeg muag khoom thiab cov neeg yuav khoom tuaj yeem muab cov pob zeb tombstones uas tiv taus lub caij ntuj no hnyav thaum khaws cia lawv cov kev zoo nkauj thiab kev ncaj ncees rau ntau xyoo.
