I-Surface Ethuthukisiwe Qeda: Izithasiselo ezifana nama-ejenti afaka umoya-mpilo zingathuthukisa ukuphela nokubukeka kukakhonkolo ngokuvimbela amaphutha njengokuqhekeka, ikhekhe lezinyosi, noma uthuli olungaphezulu, ukuqinisekisa ubushelelezi, indawo yezinga lochwepheshe.

Ukucaciswa kwe 50 ku 60 Iphesenti Lokuqukethwe Okuqinile kwe-PCE Inhlanganisela Kakhonkolo Ewuketshezi Yodaka Losimende Nokhonkolo

50– 60% Okuqukethwe Okuqinile kwe-PCE Liquid Concrete Admixture

Ikhambi Elisebenza Kakhulu Lodaka Lokhonkolo Nokhonkolo

Lokhu I-PCE fluid ingxube kakhonkolo unayo 50 ku 60 amaphesenti okuqukethwe kwewebhu okuqinile. Yenziwe nge-ether ye-polycarboxylate emisha (PCE) emisha. Into isebenza kahle kukho kokubili udaka lukakhonkolo kanye nokhonkolo olungile. Inikeza ukwehla kwamanzi aqinile ngaphandle kokulahlekelwa ukusebenza.

I-admixture ithuthukisa ukugeleza nokusabalalisa ukhonkolo omusha. Igcina ingxube ilula ukuyibeka futhi ihlangene. Ngesikhathi esifanayo, yehlisa inani lamanzi adingekayo. Lokhu kubangela ukuqina okuphezulu nokuqina okungcono kuhlaka lokugcina.

Ungasebenzisa lo mkhiqizo ezinhlotsheni eziningana zamaphrojekthi okhonkolo. Ihambisana nezici ze-precast, ukhonkolo oqinile, ama-self-compacting blends, kanye nokhonkolo opompowe. Izinga lomthamo liphansi. Futhi amanani amancane anikeza izinzuzo ezicacile. Lokhu kusiza ukulawula izintengo ngenkathi kuthuthukisa ukusebenza.

Ifomu eliwuketshezi lenza kube lula ukuphatha kanye nomthamo kuwebhusayithi. Ihlangana ngokulinganayo phakathi kwenhlanganisela. Azikho izenzo ezengeziwe ezidingekayo phakathi nokuhlanganisa. Isitoreji ngokufanayo silula kakhulu ngaphansi kwezinkinga ezivamile. Kugcine kude nezinga lokushisa eliqandayo.

Le ngxube ihlangabezana namazinga abalulekile omhlaba ezithasiselo eziphathekayo. Ayinawo ama-chloride noma ezinye izinto eziyingozi. Isebenza kahle ngamasimende ajwayelekile kanye nemikhiqizo eyisizayo efana nomlotha wempukane noma i-slag.

Izinzuzo ezibalulekile:
– Yehlisa isidingo samanzi cishe 40%.
– Yandisa isikhathi sokugcina sokusebenza.
– Ithuthukisa ukukhula kokuqina kokuqala nokokugcina.
– Ikhuthaza ukuphela kwendawo futhi yehlise ukuhlukaniswa.
– Isekela ukwakhiwa okuhlala njalo ngokusebenzisa ukhonkolo ophansi.

Sebenzisa le ngxube ye-PCE uma udinga ukusebenza kahle okuthembekile, imiphumela engaguquki, nokuxuba okuthembekile. Kuwukukhetha okuhlakaniphile kwezinhlelo zokusebenza zesimanje ezinokhonkolo lapho ikhwalithi nobulula bubalulekile.

Izicelo ze 50 ku 60 Iphesenti Lokuqukethwe Okuqinile kwe-PCE Inhlanganisela Kakhonkolo Ewuketshezi Yodaka Losimende Nokhonkolo

Izicelo ezingu-50– 60% Okuqukethwe Okuqinile kwe-PCE Fluid Admixture

Izixazululo Ezisebenza Kakhulu zikakhonkolo ne-Mortar

Le polycarboxylate ether (PCE) uketshezi oluxubile lunayo 50 ku 60 iphesenti lokuqukethwe kwewebhu okuqinile. Isebenza kahle kukho kokubili udaka lukasimende nezingxube zikakhonkolo. Abakhi bezindlu nabaklami bayisebenzisela ukuthuthukisa ukusebenza ngaphandle kokufaka amanzi engeziwe.

I-admixture inikeza ukuncishiswa kwamanzi okunamandla. Lokhu kusho ukuthi ungakwazi ukunciphisa ukuxuba amanzi kakhulu 40%. Amanzi amancane kakhulu adala amandla aphezulu kanye nokuqina okungcono kakhulu. Umkhiqizo wokugcina umelana nokuqhekeka, encipha, kanye nomonakalo wesimo sezulu.

Ihambisana nezidingo eziningi zokwakha. Abakhiqizi bemiksi elungile bafaka phakathi ukwenza ukhonkolo ogelezayo ohlala uzinzile ngesikhathi sokuthutha. Izitshalo ze-Precast ziyisebenzisela ukudiliza ngokushesha kanye nokuqedwa kwendawo okubushelelezi. Ukhonkolo ozihlanganisayo (I-SCC) futhi ithembele kule ngxube ukuthi isakaze kalula eduze kwe-rebar eqinile ngaphandle kokukhala.

Umkhiqizo ugcina ukusebenza kahle kwawo kuwo wonke amazinga okushisa ahlukene. Isebenza ezinsukwini ezishisayo zasehlobo kanye nezinkinga zasebusika ezimangalisayo. Ukuvumelana kwesethi kuhlala kuthembekile, esiza ukunciphisa imfucuza nokubamba.

Ungayixuba nezinye izixube ezijwayelekile ezinjengama-retarders noma ama-air-entrainers. Ukuhlola njalo kuxutshwa ekuqaleni ukuze kuqinisekiswe ukuhambisana. Izilinganiso zomthamo ziyahlukahluka kuye ngohlobo oluphathekayo, hlanganisa isakhiwo, kanye nezinjongo zephrojekthi. Ukusetshenziswa okuvamile kwamalungu afanayo kusuka 0.1% ku 0.5% ngesisindo sikasimende.

Izinzuzo eziyimfihlo zihlanganisa:
– Ukugcinwa okuvelele kokwehla ngesikhathi
– Umthamo ophansi odingekayo ukuze uthole imiphumela ephezulu
– Amandla athuthukisiwe ngaphambi kwesikhathi nahlala isikhathi eside
– Ukuhlanza kuqediwe ngezinkinga ezimbalwa zendawo

Osonkontileka bakhetha le ngxube ye-PCE ngoba yenza kube lula ukubeka nokuqeda. Isekela isakhiwo esihlala njalo ngokunciphisa impahla ephathekayo ngenkathi igcwalisa izinhloso zokuqina. Imisebenzi esuka emigwaqweni emikhulu ukuya ezindaweni eziphakeme incike ekusebenzeni kwayo okuvamile.

Iphrofayela Yenkampani

Singumholi womhlaba kukhonkolo ongasindi kanye nezixazululo zegwebu ezinobunjiniyela ezithuthukile. Yaziwa emhlabeni jikelele ngokuzibophezela kwayo ocwaningweni, emisha, nokusebenzisa ubuchwepheshe, besihlinzeka ngezixazululo zegwebu ezinobunjiniyela kusukela ekuqaleni kuka-2012.

Singahlinzeka ngengxube kakhonkolo yekhwalithi ephezulu kanye nemikhiqizo ehlobene nokhonkolo wegwebu emhlabeni wonke.

Le nkampani inomnyango wezobuchwepheshe oqeqeshiwe kanye nomnyango wokuqondisa izinga, ilabhorethri efakwe kahle, futhi ifakwe imishini yokuhlola ethuthukisiwe kanye nesikhungo senkonzo yamakhasimende ngemva kokuthengisa.

Uma unentshisekelo, sicela ukhululeke futhi uxhumane nathi.

5 FAQs of 50 ku 60 Iphesenti Lokuqukethwe Okuqinile kwe-PCE Inhlanganisela Kakhonkolo Ewuketshezi Yodaka Losimende Nokhonkolo

imibuzo ejwayelekile ukubuzwa: 50-60% Okuqukethwe Okuqinile kwe-PCE Inhlanganisela Kakhonkolo Ewuketshezi

Isetshenziselwa ini le ngxube??

Lo mkhiqizo uyisinciphisi samanzi esisebenza kahle kakhulu. Kuyasiza ukwenza udaka lukasimende nosimende luqine, ukusebenza okwengeziwe, futhi kulula ukuyibeka. Abakhi bayisebenzisela ukhonkolo olungile, izakhi ze-precast, kanye nezicelo ezinamandla kakhulu.

Kungani ukhetha inguqulo yokuqukethwe okuqinile okungu-50–60%.?

Okuqukethwe okuqinile okuphezulu kusho amanzi amancane emkhiqizweni. Lokhu kunikeza ukulawulwa okungcono kwemithamo futhi kunciphisa izindleko zokuthumela. Iphinde iqinisekise inqwaba yokusebenza okungaguquki ngemva kwenqwaba. Ifomula egxilile ixubana kahle futhi ihlala izinzile ngesikhathi sokugcina.

Kufanele ngingeze malini emiksini yami?

Umthamo ojwayelekile ngu 0.1% ku 0.3% ngesisindo sikasimende. Amanani aqondile ancike kumklamo wakho wokuhlanganisa, uhlobo lukasimende, nokwehla okufunayo. Njalo sebenzisa inqwaba yesilingo kuqala. Lungisa ngokusekelwe emiphumeleni yokuhlolwa kanye nezidingo zomsebenzi.

Ingabe ingahlanganiswa nezinye izixube?

Yebo, kodwa hlola ukuhambisana kuqala. Izinhlanganisela zokuhlola ngamaqoqo amancane ngaphambi kokusetshenziswa ngezinga eligcwele. Ezinye izixube zingase zisabele kahle uma zihlanganiswa ngaphandle kokuhlola okufanele. Ungalokothi ucabange ukuthi yonke imikhiqizo isebenza kahle ngokuhlangana.

Kufanele ngiyigcine kanjani le ngxube ye-liquid?

Kugcine endaweni epholile, indawo eyomile kude nelanga eliqondile. Sebenzisa iziqukathi ezivaliwe ukuze uvimbele ukungcoliswa noma ukuhwamuka. Izinga lokushisa elifanele lesitoreji liphakathi kuka-5°C no-35°C. Ungakuvumeli kube yiqhwa. Govuza ngobumnene ngaphambi kokusetshenziswa uma ukuhlukana kwenzeka.
