Yeka ukubulala uMxube wakho weMpompo: INyaniso eHlubi malunga ne-Superplasticizer Dosage

Umxube wakho wempompo uyafa. Unobangela sisithamo sakho se-Superplasticizer.

Makhe ndikugcine a $5,000 ugalele kunye nentloko enkulu. Eyona mpazamo iyingozi kakhulu ekumpompeni ikhonkrithi kukukholelwa ukuba i-superplasticizer encinci ilungile, ngakumbi kungcono. Ayiyo. Awuyi kufumana ukuwohloka ngakumbi. Awuyi kufumana lula ukumpompa. Uya kufumana okwahlukileyo, ukopha ubumdaka obuvale umgca wakho kwaye ushiye ubuthathaka, ilitye eliqhekekileyo. Ndibone abaqhubi bezityalo ze-batch besonakalisa zonke iilori ngenxa yokuba basukela ukudilika okuphezulu ngokudubula okongezelelekileyo kwePCE.. Yiyeke. Elona liphezulu idosi ye-superplasticizer yekonkrithi emponthiweyo uhlala kwifestile emxinwa kakhulu. Uyiphose ngezishumi ezimbalwa zeepesenti, kwaye ungowakho ukusilela.

I-Overdose imbi ngakumbi kune-Underdose: Umjikelo wokuFa

Nantsi inyani ephikisayo eyaziyo yonke indoda yempompo enamava: I-overdosing superplasticizer ibangela ukukhawuleza, ilahleko yokuthotywa eyintlekele ngakumbi kunokuthoba umthamo. Ukunciphisa idosi kukunika ukuqina ikhonkrithi. Iyacaphukisa, Ewe. Kodwa i-concrete eqinile inokuphinda iphinde iphinde iphinde iqhutywe okanye iphathwe ngokucofa okuthambileyo emanzini. Ukugqithisa ngokweqile? Oko kubangela ukusabela okugqithisileyo kwemichiza. I-C3A kwisamente yakho itya i-dispersant. Ukuwa kuyawa. Ufumana ngokukhawuleza, ukuqina okungaqhelekanga. Wongeza umxube ongakumbi. Umjikelo uyaphinda. Ikhonkrithi iba yinto encangathi, umthwalo ongasebenzekiyo. Uxinzelelo lwempompo yakho luyenyuka. Umgca uyancokola. Emva koko iyayeka. Ngoku wophula umbhobho. I idosi ye-superplasticizer yekonkrithi emponthiweyo ayisiyiyo ingcebiso; kukunyamezelana.

Umgibe wokwahlulahlula ongenakuwubona

Idosi egqithisileyo ayisoloko ibonakala ngoko nangoko. Ngamaxesha athile, ikhonkrithi ibonakala inkulu kwigubu. Iqukuqela njengamanzi. Ucinga ukuba uphumelele. Emva koko uyayimpompa 200 iinyawo. Ukungcangcazela kunye noxinzelelo lwahlula intlama kwi-aggregate. Ingxondorha yamatye arhabaxa kwisinciphisi. Udaka lubaleka phambili. Unomgca ozele ngamatye. Umsebenzisi wempompo uqalekisa igama lakho. Oku akuyongxaki yezixhobo. Le yimpazamo yedosi. I idosi ye-superplasticizer yekonkrithi emponthiweyo kufuneka ibalwe ngononophelo ukugcina intlama viscosity phezulu konele ukumisa i-aggregate phantsi koxinzelelo lwempompo. I-superplasticizer kakhulu, kwaye loo viscosity iyaphela.

Idatha ayixoki: I 0.5% ukuya 3% Ifestile

Ungalithabathi ilizwi lam kulo. Jonga uncwadi. I-ACI 211.1 umgangatho, kudityaniswe namashumi eminyaka edatha yendawo evela kwi-NRMCA, iqinisekisa ukuba uluhlu olusebenzayo oluqhelekileyo oluphezulu-uluhlu lwamanzi izinciphisi-i-superplasticizers ezenza ukumpompa kwenzeke-yinto 0.5% ukuya 3% ngobunzima bemathiriyeli yesamente. Yifestile yakho leyo. Kodwa nanku umkhabi: ayingoluhlu olusicaba. I-PCE (polycarboxylate ether) imveliso iya kuhlala isebenza ngokugqibeleleyo 0.6% ukuya 1.2%. Kusenokufuneka i-sulfonate naphthalene endala 1.5% ukuya 2.5%. Ukutyhala iPCE ngaphaya 1.5% ngaphandle kovavanyo oluthile lokuhambelana ucela ukopha. Ndivavanyile 47 indibaniselwano ezahlukeneyo zesamente-imixube kumsebenzi wam. Umgca phakathi kokuhamba ngeyona ndlela kunye nokusilela okuyintlekele phantse awuzange ube banzi kunoko 0.3% ubunzima bokudibanisa. Hlonipha loo mda wethamo.

Iiguquguquko ezine ongenakuzihoya

Awunakuseta idosi yakho ngetshathi eseludongeni elebhu. Iconcrete yenyani empompo ngenkohlakalo. Nazi izinto ezine eziza kutshabalalisa yakho idosi ye-superplasticizer yekonkrithi emponthiweyo ukuba awubahoyi. Ekuqaleni, ukulungiswa kwesamente. Isamente ene-fineness kaBlaine ngaphezulu 400 m2/kg iya kuthoba i-superplasticizer njengesipontshi. Idosi yakho kufuneka inyuke. Isibini, ukufunxa ngokupheleleyo. Isanti yekalika enxaniweyo ene 2.5% Ukufunxa kuya kuba amanzi kwintlama yakho, ukunciphisa umlinganiselo osebenzayo we-w / c kunye nokwenza umxube uqine, kunye nedosi ephezulu ye-superplasticizer. Isithathu, ubushushu. Rhoqo nge-5°C ukunyuka kobushushu be-ambient kunganciphisa ugcino lwakho lokuwohloka 30 imizuzu. Kufuneka uhlengahlengise idosi okanye usebenzise inguqulelo ebambezelayo. Isine, bhabha uthuthu okanye slag. Ezi zixube zamaminerali zitshintsha i-particle surface chemistry. A 20% fly ash replacement inokuvumela idosi esezantsi, kodwa a 50% indawo ye-slag ingafuna a 40% umthamo ophezulu. Yivavanye. Ungaze ucinge.

Uvavanyo lokuhambelana olugcina umsebenzi wakho

Uhlengahlengiso Lwentsimi: Ubugcisa bo 'Live’ Iqela

Nokuba ngedatha yaselebhu egqibeleleyo, iimeko zentsimi shift. Ingqumba edibeneyo iba manzi ngenxa yemvula. Iqondo lobushushu lesamente liyanyuka lisuka kwisisele. Ilori ihlala kwitrafikhi ixesha elongezelelweyo 20 imizuzu. Kufuneka ulungise i idosi ye-superplasticizer yekonkrithi emponthiweyo ngexesha lokwenyani. Kodwa kukho umgaqo: Ungaze uhlengahlengise ithamo kwilori enye ngokungaphezulu 20% yeresiphi yokuqala ngaphandle kwebhetshi entsha yesilingo. Kwaye soze, uke wongeze i-superplasticizer emva kokuba ikhonkrithi iqalile ukuseta. Leyo yindlela eqinisekisiweyo yokufumana iseti ethambileyo okanye ingeniso yamandla enguziro. Kunoko, lawula imeko ngokulawula isithuba sonikezelo. Ukuba ikhonkrithi ifika iqine kakhulu, yithumele emva kwaye unciphise isantya somgca, okanye ucele umthwalo ophantsi wobushushu. Musa ukuphatha i-superplasticizer njenge-magic re-fluidizer. Ayiyo. Sisixhobo sekhemikhali esichanekileyo. Yisebenzise kakubi, kwaye iya kwaphula ikhonkrithi yakho.

The Dosage Calculation Trap: Iilitha vs. Ipesenti

Ndiyibona le mpazamo mihla le kwiindawo zemisebenzi. I-spec iyabiza 1.5% superplasticizer ngokobunzima binder. Umsebenzisi webhetshi uyabala 1.5% ye 600 kg yezinto zesamente, oko ikukuthi 9 ikg. Kodwa umxube wakhe lulwelo olunobunzima obuthile 1.1. Kufuneka athathe idosi malunga 8.2 iilitha. Uyaqikelela. Okanye, usebenzisa i-dosage ephakanyisiweyo yomenzi kwiilitha nge-cubic meter nganye ngaphandle kokujonga umxholo we-binder. Ukuba umxholo wokubopha uphantsi, udla ngokugqithisileyo. Ukuba iphezulu, wenza ngaphantsi. I idosi ye-superplasticizer yekonkrithi emponthiweyo kufuneka ivakaliswe ngokungaguqukiyo. Ndiyalela ukubalwa kwetshekhi ezimbini: okokuqala njengepesenti yesibophelelo ngobunzima bokuqina okusebenzayo, okwesibini njengomthamo kwi-cubic meter yekhonkrithi. Bathelekise. Ukuba abavumelani, unempazamo yokubala. Yilungise ngaphambi kokuba ikhonkrithi ihlanganiswe. Impazamo yomntu ibulala ikhonkrithi eyongezelelekileyo kunekhemistri.

Isilumkiso sokugqibela: Xa Umoya omninzi ingengoMhlobo Wakho

Umgibe wokugqibela. Ukugqithisa ngokweqile ngezinye ii-superplasticizers, ngokukodwa iintlobo ze-PCE kumanqanaba aphezulu, kunokubangela ukungena komoya ngokugqithisileyo. Ucinga ukuba ufumana ukumpompa, kodwa okunene uyafundisa 7% ukuya 9% umoya. Loo moya unciphisa amandla akho acinezelayo 20% okanye ngaphezulu. Ikhonkrithi ibonakala igcwele kwaye i-creamy, kodwa ibekwe engozini. Uyayimpompa, igcwalisa ifom, kwaye iyasilela ikhefu leentsuku ezingama-28. I idosi ye-superplasticizer yekonkrithi emponthiweyo kufuneka iqinisekiswe ngovavanyo lomxholo womoya omtsha kuwo wonke umthwalo ukuba ukrokrela ukugqithisa. Ukuba umoya uphelile 4% kumxube osemgangathweni, unengxaki. Musa ukuyamkela. Lungisa idosi phantsi.

Umgca ongezantsi

Musa ukufunda esi sifundo ngokucoca umgca wepompo odibeneyo okanye ngokuphula isilinda esibuthathaka. I idosi ye-superplasticizer yekonkrithi emponthiweyo sisenzo esibuthathaka sokulinganisa. Ifuna intlonipho. Ifuna uvavanyo. Ifuna ulwazi lwangaphandle. Okuninzi akuthethi ukuba ngcono. Kuthetha ikhonkrithi eyaphukileyo. Vavanya izixhobo zakho. Bala umthamo wakho. Jonga ukugcinwa kwakho kwe-slump. Themba ibhetshi yakho yesilingo. Ngoku phuma apho kwaye ugalele ikhonkrithi esebenzayo. Umsebenzisi wakho wempompo kunye nomxhasi wakho uya kukubulela.
