pem teb sib tsoo khoom siv

Piav qhov tshiab ACI polished pob zeb slab tiav specification. Tab sis ua ntej, vim li cas peb thiaj xav tau cov lus qhia tshwj xeeb?
Polished pob zeb slabs tau dhau los ua neeg nyiam, yog li cov neeg cog lus yuav tsum muaj txoj hauv kev los tsim lawv nrog cov khoom zoo sib xws. Raws li cov ntaub ntawv los ntawm Grand View Research, lub pob zeb polished thaum ntxov pib hauv 1990s, tab sis los ntawm 2019, hais txog cov nyiaj tau los, polished pob zeb hauv pem teb suav txog kwv yees li 53.5% ntawm Teb Chaws Asmeskas cov pob zeb hauv pem teb txheej lag luam. Niaj hnub no, polished pob zeb slabs tuaj yeem pom hauv khw muag khoom noj, chaw ua haujlwm, khw muag khoom, lub thawv loj, thiab tsev. Cov yam ntxwv muab los ntawm polished pob zeb hauv pem teb yog tsav qhov nce hauv kev siv, xws li kev ua haujlwm siab, lub neej ntev, kev saib xyuas yooj yim, tus nqi-zoo, siab lub teeb pom kev zoo thiab zoo nkauj. Raws li kev cia siab, kev lag luam yuav tsum nce ntxiv hauv ob peb xyoos tom ntej no.
Qhov gloss (reflectance) ntsuas ntawm polished pob zeb slab qhia tau hais tias ntau npaum li cas gloss ntawm qhov chaw. Cov pob zeb polished ntawm no qhia txog lub teeb pom kev zoo ntawm Sprouts Farmer's Market. Diam duab courtesy Patrick Harrison ua tau raws li qhov xav tau no, thiab tam sim no muaj polished pob zeb slab tiav specification (ACI 310.1) txiav txim siab yam tsawg kawg nkaus uas polished pob zeb slabs yuav tsum tau raws li. Txij li thaum muaj ib txoj hauv kev los txheeb xyuas cov kev xav tau thiab cov txiaj ntsig, nws yooj yim dua kom ua tau raws li tus kws tsim vaj tsev / engineers qhov kev cia siab. Qee zaum, cov txheej txheem yooj yim xws li ntxuav hauv pem teb slabs yuav txhais tau ntau txoj hauv kev rau cov kws tsim vaj tsev / engineers thiab cov neeg cog lus. Siv ACI 310.1 specification tshiab, kev pom zoo tuaj yeem ncav cuag thiab tam sim no tus neeg cog lus tuaj yeem ua pov thawj tias cov ntsiab lus tau teev tseg hauv daim ntawv cog lus tau ua tiav. Ob tog tam sim no muaj cov lus qhia rau kev lag luam ib txwm ua. Raws li nrog rau tag nrho cov qauv ACI, cov lus qhia tshwj xeeb yuav raug tshuaj xyuas thiab hloov kho raws li qhov xav tau hauv ob peb xyoos tom ntej no kom muaj kev cuam tshuam cov kev xav tau ntawm kev lag luam.
Cov ntaub ntawv nyob rau hauv ACI 310.1 tshiab specification yog ib qho yooj yim mus nrhiav tau vim hais tias nws ua raws li tus qauv peb feem hom, uas yog General, Khoom, thiab Execution. Muaj cov ncauj lus kom ntxaws txog kev kuaj thiab tshuaj xyuas, kev tswj xyuas zoo, kev ruaj ntseg zoo, kev ntsuam xyuas, kev lees paub thiab kev tiv thaiv ntawm polished pob zeb slab tiav. Hauv qhov kev siv, nws suav nrog qhov yuav tsum tau ua kom tiav, xim, sib tsoo thiab polishing, thiab tu.
Cov lus qhia tshiab pom tau tias txhua qhov project muaj ntau qhov sib txawv uas yuav tsum tau txiav txim siab. Cov kws kes duab vajtse / engineers cov ntaub ntawv yuav tsum tau qhia meej txog cov kev cai tshwj xeeb ntawm qhov project, xws li kev nthuav dav thiab kev xav zoo nkauj. Cov ntawv teev npe yuav tsum tau ua thiab cov kev xaiv uas yuav tsum tau teev qhia cov kws kos duab / engineers los kho cov kev qhia tshwj xeeb raws li tus neeg yuav tsum tau ua, txawm tias nws yog los txheeb xyuas daim iav gloss ntawm polished phaj tiav, ntxiv xim lossis xav tau kev sim ntxiv.
Cov lus qhia tshiab qhia kom xav tau kev ntsuas zoo nkauj thiab txhais tau tias yuav tsum khaws cov ntaub ntawv li cas. Qhov no suav nrog qhov tsis sib xws ntawm cov duab (DOI), uas suav nrog kev ua kom pom tseeb thiab qhov zoo ntawm qhov chaw ntawm cov nplais hauv cov txheej txheem polishing, yog li nws muaj txoj hauv kev los ntsuas nws qhov zoo. Gloss (reflectance) yog ib qho kev ntsuas qhia tias ci ntsa iab li cas. Kev ntsuas muab lub hom phiaj txhais ntau dua ntawm qhov zoo nkauj ntawm qhov chaw. Haze kuj tau txhais nyob rau hauv cov ntaub ntawv, uas feem ntau qhia tau hais tias ib nrab cov khoom raug suav nrog los tsim kom zoo nkauj.
Tam sim no, kev ntsuam xyuas ntawm polished pob zeb slabs tsis zoo ib yam. Ntau tus neeg cog lus tsis tau sau cov ntawv nyeem txaus thiab xav tias lawv tau ua tiav qee qhov ntsuas kev ua tau zoo ntawm kev zoo nkauj. Cov neeg cog lus feem ntau tsuas yog sim ib qho qauv me me thiab tom qab ntawd xav tias lawv siv tib cov ntaub ntawv thiab cov tswv yim los tsim cov polishing cov txiaj ntsig yam tsis tau sim lub rooj zaum kawg. Qhov tshiab ACI 310.1 specification muab lub hauv paus rau kev soj ntsuam zoo ib yam nyob rau hauv ib hnub thiab yuav ua li cas qhia cov txiaj ntsig. Kev sim ua haujlwm tsis tu ncua kuj tseem muab cov neeg cog lus nrog cov ntaub ntawv keeb kwm ntsuas cov txiaj ntsig uas tuaj yeem siv rau hauv kev sib tw yav tom ntej.
Qhov tshiab polished pob zeb slab tiav specification (ACI 310.1) muab tus qauv yam tsawg kawg nkaus siv tau rau txhua qhov polished pob zeb ua tiav. Cabela's yog ib qho ntawm cov khw muag khoom lag luam paub txog kev siv polished pob zeb slabs. Kev lees paub los ntawm Patrick Harrison. Tus tshiab ACI 310.1 specification kuj txiav txim siab cov kev xeem uas yuav tsum tau ua thiab qhov chaw ntawm txhua qhov kev xeem.
Cov ntaub ntawv tshiab muaj qhia txog thaum yuav ua ntau hom kev xeem. Piv txwv li, tsawg kawg ob lub lis piam ua ntej tus tswv muaj nws, qhov kev ntsuam xyuas yuav tsum muaj xws li specular gloss raws li ASTM D523, duab clarity (DOI) raws li ASTM 5767, thiab haze raws li ASTM D4039. Tus tshiab ACI 310.1 specification kuj qhia qhov chaw xeem rau txhua hom kev xeem, tab sis tus tsim cov ntaub ntawv yuav tsum tau txiav txim siab yam tsawg kawg nkaus yuav tsum tau rau DOI, gloss thiab haze. Los ntawm kev muab cov kev taw qhia txog qhov kev xeem twg yuav tsum ua thiab thaum twg, cov ntaub ntawv muab ib txoj hauv kev los xyuas kom meej tias cov slab ua tau raws li cov lus qhia hauv daim ntawv cog lus.
Kev ntsuam xyuas thiab tshaj tawm kev sib txuas lus yog qhov tseem ceeb kom ntseeg tau tias txhua tus neeg sab nrauv - cov tswv, kws tsim vaj tsev / engineers, thiab cov neeg cog lus - paub tias cov slab ua tau raws li qhov pom zoo. Qhov no yog qhov teeb meem yeej-yeej: kom paub meej tias tus tswv muab cov khoom lag luam zoo, thiab cov neeg cog lus muaj cov lej ntsuas los ua pov thawj ua tiav.
ACI 310.1 tam sim no muaj nyob rau ntawm ACI lub vev xaib, thiab nws tau tsim los ntawm kev sib koom tes ntawm ACI thiab American Association of Concrete Contractors (ASCC). Txhawm rau pab cov neeg cog lus ua raws li cov qauv yam tsawg kawg nkaus tau teev tseg, ASCC tab tom tsim cov lus qhia rau cov neeg cog lus uas cuam tshuam cov qauv hauv cov cai no. Ua raws li cov qauv tshiab ntawm ACI 310.1 specification, phau ntawv qhia yuav muab cov lus qhia thiab cov lus piav qhia hauv txhua qhov chaw uas tus neeg cog lus yuav xav tau kev taw qhia ntxiv. ASCC's ACI 310.1 kev taw qhia yuav tsum tau tshaj tawm nyob rau nruab nrab-2021.
Thawj polished pob zeb slab specification los ntawm American Concrete Institute (ACI) yog tam sim no muaj nyob rau ntawm ACI lub website. Tus tshiab polished pob zeb slab tiav specification (ACI 310.1) tsim los ntawm ACI-ASCC Joint Committee 310 yog ib tug siv specification tsim los muab cov yam tsawg kawg nkaus tus qauv uas architects los yog engineers siv tau rau tej polished pob zeb slab. ACI 310.1 specification siv rau hauv pem teb slabs thiab tshem tawm hauv pem teb slabs. Thaum hais hauv cov ntaub ntawv cog lus, nws muab cov txheej txheem tiav pawg thawj coj saib pom zoo ntawm tus neeg cog lus thiab tus kws tsim vaj tsev lossis tus kws tsim khoom.
Architects / engineers tam sim no tuaj yeem xa mus rau ACI 310.1 cov lus qhia tshiab hauv cov ntaub ntawv cog lus thiab qhia tias polished pob zeb hauv pem teb yuav tsum ua raws li cov lus qhia tshwj xeeb, lossis lawv tuaj yeem teev cov kev cai nruj dua. Qhov no yog vim li cas cov ntaub ntawv no hu ua cov lus qhia tshwj xeeb vim nws muab qhov pib qis tshaj plaws rau polished pob zeb slabs. Thaum hais, qhov kev qhia tshiab no yog suav tias yog ib feem ntawm daim ntawv cog lus ntawm tus tswv thiab tus neeg cog lus, thiab nws yog ib qho tseem ceeb rau txhua tus neeg cog lus polishing kom nyeem cov lus qhia los ntawm kev nkag siab nws.
