Tsanangura iyo itsva ACI yakakwenenzverwa kongiri slab kupedzisa kutsanangurwa. Asi kutanga, nei tichida tsanangudzo?
Yakakwenenzverwa kongiri slabs iri kuramba ichizivikanwa, saka makondirakiti anofanirwa kunge aine nzira dzekuagadzira nemhando yepamusoro inowirirana. Zvinoenderana nedata kubva kuGrand View Research, yekutanga yakakwenenzverwa kongiri pasi yakatanga muma1990s, asi panosvika 2019, maererano nemari, yakakwenenzverwa kongiri pasi yakaverengera ingangoita 53.5% yeUS kongiri yepasi coating musika. Nhasi, akakwenenzverwa kongiri slabs anogona kuwanikwa muzvitoro zvegirosari, mahofisi, zvitoro zvezvitoro, mabhokisi mahombe, uye dzimba. Mamiriro akapihwa neakakwenenzverwa kongiri pasi ari kutyaira kuwedzera kwekushandiswa, senge kusimba kwepamusoro, hupenyu hurefu, kugadzirisa kuri nyore, kudhura-kushanda, kupenya kwechiedza uye aesthetics. Sezvinotarisirwa, chikamu chinotarisirwa kuwedzera mumakore mashoma anotevera.
Kupenya (reflectance) kuyerwa kwekongiri yakakwenenzverwa kunoratidza kuti kupenya kwakadii kwepasi. Masirabhu ekongiri akakwenenzverwa pano anoratidza kuvhenekera kwepamusoro kweMusika weSprouts Farmer. Mufananidzo neruremekedzo Patrick Harrison unosangana nechido ichi, uye ikozvino iripo yakakwenenzverwa kongiri yekupedzisa kutsanangurwa (ACI 310.1) inosarudza hushoma mwero iyo yakakwenenzverwa kongiri slabs inofanira kusangana. Sezvo paine nzira yekutsanangura nzira dzinotarisirwa uye mhedzisiro, zviri nyore kusangana neanovaka / tarisiro yeinjiniya. Dzimwe nguva, maitiro ekutanga akadai sekuchenesa pasi slabs anogona kureva nzira dzakasiyana dzevagadziri / mainjiniya uye makondirakiti. Uchishandisa iyo itsva ACI 310.1 yakatarwa, kubvumirana kunogona kusvikwa uye kontrakta anogona kuratidza kuti izvo zvakatsanangurwa mukondirakiti zvasangana. Mapato ese ari maviri zvino ane nhungamiro yezvakajairwa maindasitiri maitiro. Sezviyero zvese zveACI, zvakatemwa zvichawongororwa nekuvandudzwa sezvinodiwa mumakore mashoma anotevera kuratidza zvinodiwa neindasitiri.
Ruzivo rwuri muiyo itsva ACI 310.1 tsanangudzo iri nyore kuwana nekuti inoteedzera yakajairwa-zvikamu zvitatu fomati, zvinoti General, Product, uye Execution. Pane zvakadzama zvinodiwa pakuyedzwa uye kuongorora, kudzora kwemhando, vimbiso yemhando, kuongorora, kugamuchirwa uye kuchengetedzwa kweakakwenenzverwa kongiri inopera. Muchikamu chekushandisa, chinosanganisira kupedzisa kwepamusoro zvinodiwa, kuisa mavara, kukuya uye kupukuta, uye kugadzirisa.
Iyo nyowani nyowani inoziva kuti purojekiti yega yega ine zvakawanda zvakasiyana zvinofanirwa kutsanangurwa. Gwaro remugadziri/injiniya rinoda kujekesa zvinodikanwa zvepurojekiti, senge kuratidzwa kwese uye zvinotarisirwa zvinoyevedza. Rondedzero yezvinosungirwa inosanganisirwa uye sarudzo inodiwa rondedzero inotungamira vagadziri / mainjiniya kuti vagadzirise zvakatemwa zvinoenderana nezvinodiwa zvepurojekiti yemunhu, kungave kutsanangura girazi girosi rekupera kwendiro yakakwenenzverwa, kuwedzera ruvara kana kuda kumwe kuedzwa.
Iyo nyowani nyowani inokurudzira kuti inoda aesthetic kuyerwa uye kutsanangura kuti data rinofanira kuunganidzwa sei. Izvi zvinosanganisira iyo yakasiyana-siyana yemufananidzo (DOI), iyo inosanganisira kupinza uye kunaka kwepamusoro pe slab mukutevedzana kwematanho ekupenya, saka kune nzira yekuyera kunaka kwayo. Gloss (reflectance) chipimo chinoratidza kupenya kwakaita nzvimbo. Chiyero chinopa tsananguro ine chinangwa chepamusoro aesthetics. Haze inotsanangurwa zvakare mugwaro, iro rinowanzoratidza kuti zvigadzirwa zvechikamu zvinosanganisirwa kugadzira aesthetics.
Parizvino, bvunzo pane yakakwenenzverwa kongiri slabs haina kuenderana. Vazhinji makondirakiti havana kuunganidza kuverenga kwakakwana uye vakafungidzira kuti vakawana imwe inoyerwa nhanho yekuita maererano neaesthetics. Makontrakta anowanzo kuyedza diki modhi nzvimbo vobva vafunga kuti vanoshandisa zvinhu zvakafanana uye matekiniki kuburitsa mhedzisiro yekupukuta pasina kunyatso edza yekupedzisira bhodhi. Iyo ichangobva kuburitswa ACI 310.1 yakatarwa inopa hurongwa hwekuyedzwa kunoenderana zuva rese uye maitiro ekutaura mhinduro. Kuyedzwa kunoenderana kwebasa kunopawo makondirakiti nhoroondo inoyerwa yemhedzisiro inogona kushandiswa mune ramangwana mabhidhi.
Iyo nyowani yakakwenenzverwa kongiri yekupedzisa kutsanangurwa (ACI 310.1) inopa hushoma mwero inoshanda kune chero yakakwenenzverwa kongiri slab kupera. Cabela's ndeimwe yezvitoro zvinozivikanwa nekushandisa akakwenenzverwa kongiri slabs. Kutendeseka naPatrick Harrison. Iyo itsva ACI 310.1 yakatarwa zvakare inotarisa bvunzo dzinofanirwa kuitwa uye nzvimbo yebvunzo yega yega.
Gwaro richangowanikwa rinoratidza nguva yekuita mhando dzakasiyana dzebvunzo. Semuenzaniso, angangoita mavhiki maviri muridzi asati ave nayo, bvunzo dzinofanirwa kusanganisira specular gloss zvinoenderana neASTM D523, mufananidzo kujeka (DOI) zvinoenderana neASTM 5767, uye haze zvinoenderana neASTM D4039. Iyo nyowani ACI 310.1 yakatarwa inotsanangurawo nzvimbo yekuyedza yemhando yega yega yebvunzo, asi mugadziri werekodhi anofanirwa kuona izvo zvishoma zvinodikanwa zveDOI, gloss uye haze. Nekupa gwara rekuti ndedzipi bvunzo dzekuita uye riini, gwaro rinopa nzira yekuona kuti slab inosangana nezvinodiwa zvakataurwa muchibvumirano.
Kuedza uye kurondedzera kutaurirana kwakakosha kuve nechokwadi chekuti mapato ese-varidzi, vavaki / mainjiniya, uye makondirakiti-vanoziva kuti slab inosangana nemhando yakabvumiranwa. Iyi inzvimbo yekukunda-kukunda: kuve nechokwadi chekuti muridzi anopa zvigadzirwa zvemhando yepamusoro, uye kontrakta ane nhamba dzinoyerwa kuratidza kubudirira.
ACI 310.1 yave kuwanikwa pawebhusaiti yeACI, uye yakagadzirwa kuburikidza nekuedza pamwe pakati peACI neAmerican Association of Concrete Contractors (ASCC). Kubatsira makondirakiti kutevedzera zviyero zvishoma zvakatsanangurwa, ASCC parizvino iri kugadzira nhungamiro kune makondirakiti anoratidza zviyero mukodhi iyi. Kutevera chimiro cheiyo itsva ACI 310.1 yakatarwa, gwara rinopa mhinduro uye tsananguro munzvimbo dzese uko kontrakiti angangoda humwe hutungamiriri. ASCC's ACI 310.1 kutungamira inotarisirwa kuburitswa pakati-2021.
Yekutanga yakakwenenzverwa kongiri dhizaini kubva kuAmerican Concrete Institute (ACI) yave kuwanikwa pawebhusaiti yeACI. Iyo nyowani yakakwenenzverwa kongiri yekupedzisa dhizaini (ACI 310.1) yakagadziridzwa neACI-ASCC Joint Committee 310 ireferensi yakatarwa yakagadzirirwa kupa hushoma chiyero icho vagadziri vezvivakwa kana mainjiniya vanogona kushandisa kune chero yakakwenenzverwa kongiri slab. Iyo ACI 310.1 yakatarwa inoshanda kune pasi pasi slabs uye yakamiswa pasi slabs. Kana yatorwa mumagwaro echibvumirano, inopa iyo yakapedzwa bhodhi mwero wakabvumiranwa pakati pekontrakta nemuvaki kana mainjiniya.
Vagadziri / mainjiniya vanogona ikozvino kutaura kune itsva ACI 310.1 kutsanangurwa mumagwaro ekondirakiti uye vanoratidza kuti yakakwenenzverwa kongiri pasi inofanirwa kutevedzera zvakatemwa, kana kuti vanogona kutsanangura zvakanyanya kuomesesa zvinodiwa. Ndosaka gwaro iri richinzi referensi yekumisikidza nekuti rinopa yakaderera pekutangira kweakakwenenzverwa kongiri slabs. Kana yataurwa, iyi tsvakiridzo itsva inoonekwa sechikamu chegwaro rechibvumirano pakati pemuridzi nekondirakiti, uye zvakakosha kuti mugadziri wega wega anopukuta averenge zvakatemwa kuti azvinzwisise.
