Okubaluleke Kakhulu Ekugadeni Izinga Lokusebenza Kakhonkolo Nokuswakama Ngaphansi Kwezimo Zezulu Ezinzima

Kubaluleke Kakhulu Ekugadweni Kwezinga Lokushisa Kakhonkolo Nokuswakama Ngaphansi Kwezimo Zezulu Ezinzima

Izimo zezulu zinomthelela omkhulu ekwelapheni nasekuqineni kukakhonkolo.Esikhathini esibandayo, ukhonkolo uphulukisa kancane, okunciphisa amandla awo.Ngokhonkolo lwesimo sezulu esishisayo, izinkinga zingenzeka lapho umswakama ususwa ku-slab kakhonkolo ngokushesha kakhulu.Lokhu kudinga ukugadwa ngokunembileIzinzwa zokushisa nomswakamaukuqinisekisa ukuthi usimende wenza inqubo efanele yokwelapha.

1. I-hydration kakhonkolo

Lapho izilinganiso ezinjengesihlabathi namatshe zixutshwa nosimende namanzi, ukushisa kuyanda nakho.Ukushisa okukhiqizwa kulokhu kusabela kwe-exothermic kubizwa ngokuthi ukushisa kwe-hydration.Amandla e-hydration yiwo adala ukuthi ukhonkolo uqine.

Phakathi nenqubo ye-hydration, ukusabela kwamakhemikhali okuhlukile kuvame ukwenzeka ngesikhathi esisodwa.Lokhu kusabela kubangela "imikhiqizo ye-hydration".Le mikhiqizo ye-hydration ibangela ukuthi izinhlayiya zesihlabathi, amatshe, nezinye izakhi zinamathelane futhi zakhe amabhlogo kakhonkolo.

2. Izigaba ezinhlanu zokuguquguquka kokushisa okukhonkolo

Ukuziphendukela kwemvelo okushisayo kukhonkolo kuyinqubo eyinkimbinkimbi enomthelela omkhulu emandleni okhonkolo.Le nqubo ihlukaniswe izigaba ezi-5 ezahlukene.Isiteji ngasinye sinomugqa wesikhathi othize kanye nokusabela kwamakhemikhali, kuye ngengxube kakhonkolo.

a.Ukusabela kokuqala.

Isigaba sokuqala senqubo ye-hydration sizoqala ngemuva nje kokuba amanzi ethelwe kusimende.Khona-ke, ukwanda okungazelelwe kwezinga lokushisa kulindeleke.Lokhu kuzokwenzeka ngokushesha futhi kugcine kuphela imizuzu eyi-15-30, kuye ngohlobo lukasimende olusetshenzisiwe.

b.Isikhathi sokulala.

Ngemuva kokusabela kokuqala, i-compound izomboza ubuso bezinhlayiya ze-cement, okuzoholela ekunciphiseni izinga le-hydration.Uma lokhu kwenzeka, kuyisigaba sesibili sokuguquka kokushisa kwekhonkrithi, eyaziwa nangokuthi isigaba sokungeniswa, okuyisikhathi sokungena lapho ukhonkolo ungakabi lukhuni, futhi ukuthuthwa nokubekwa kokhonkolo kufanele kuqedwe. phakathi nalesi sigaba.

c.Isikhathi sokusheshisa amandla.

Esigabeni sesithathu, ukhonkolo uqala ukuthola amandla futhi ngaleyo ndlela uqinise, uphenduke ube yinqwaba eqinile futhi eqinile.Ukushisa kwe-hydration kukhuphuka ngokulingene kuze kufinyelele endaweni ephezulu kakhulu.Izimo zezinga lokushisa kanye nomswakamo ngalesi sikhathi zigadwa kusetshenziswa izinzwa zokushisa nokuswakama, okuvumela ukhonkolo ukuthi kancane kancane usethe futhi ufinyelele ebangeni elifanele.Imikhiqizo ye-Hengko enezinhlanganisela eziningi zokushisa nomswakama ihlangabezana nezinhlobonhlobo zezidingo zamakhasimende, njengokuhlinzeka ngezinhlobonhlobo zedijithali ezisezingeni eliphezulu.amazinga okushisa kanye nomswakama wezinzwa: Ukuze uthumele isidlulisi, udinga uphenyo oluxhumekayo.Isibonelo, sebenzisa i-probe enenzwa ephezulu yokunemba, eqinile yesikhathi eside yokushisa okubanzi kwenqubo kanye nezindawo;ubuchwepheshe be-intelligent probe: ukushintshwa okulula kwe-probe, isixhumi esibonakalayo se-transmitter digital, nemiqondo yokulinganisa ehlakaniphile.

d.Ukunciphisa.

Isigaba sesine senzeka ngesikhathi lapho ukushisa kwe-hydration kufinyelela izinga lokushisa eliphakeme kakhulu.Ukushisa kwe-hydration kuqala ukwehla njengoba i-hydrate eyakhiwe iba ungqimba oluvikelayo lwengxenye engakaphenduli.Amandla amaningi atholakele futhi ngokuvamile ahlala amahora ambalwa, uma kungenjalo izinyanga.Ngemuva kokuthi amandla adingekayo efinyelelwe, i-formwork iyasuswa kulesi sigaba.

e.Izwe elizinzile.

Inqubo ye-hydration iqedwa lapho isigaba sesi-5 sifinyelelwa.Ukusabela okushisayo ku-hydration kuhamba kancane, cishe ngezinga elifanayo njengesigaba sokulala.Isigaba sokugcina senqubo ye-hydration singahlala izinsuku, izinyanga, noma ngisho neminyaka size siqedwe futhi sithole amandla aso okugcina.

3. Ukubaluleka kweukuqapha izinga lokushisa nomswakama

Isigaba ngasinye senqubo ye-hydration sinezinga lokushisa elihlukile.Ngakho-ke, ukuqapha okungaguquki nokuqondile kwesigaba ngasinye kubalulekile ukuze kugcinwe izinga lokushisa elincane elivumelekile kuyo yonke inqubo.Ngeshwa, izimo zezulu ezimbi kakhulu zenza lokhu kushisa kube nzima kakhulu ukuligcina.

Ngokuya ngezimo zezulu, amazinga okushisa okukhonkolo agcinwa phakathi kuka-40-90F.Esimweni sezulu esibandayo, amazinga okushisa okukhonkolo agcinwa ngaphezu kuka-40F.Ngokuphambene, umkhawulo wokushisa ophezulu wesimo sezulu esishisayo ngu-90F.

Kuthathwa izinyathelo zokuphepha ukuxuba, ukubeka kanye nokugcina ukhonkolo esimweni sezulu esishisayo.Osonkontileka kudingeka bahambisane nemikhawulo yezinga lokushisa ngokuqapha.Uma kungenjalo, i-hydration ngeke yenzeke kahle futhi kungase kuphakame izinkinga.

Okunye okungalungile ngesimo sezulu esibandayo ukuqandisa kukakhonkolo ngaphambi kwesikhathi.Lokhu futhi kunciphisa amandla kakhonkolo kuze kufike ku-50%.Kulesi simo, kubalulekile ukuvimbela ukhonkolo kusuka emakhazeni.

Izinga lokushisa likakhonkolo esimweni sezulu esibi liyahlukahluka kuye ngezimo zemvelo zangempela.Izinyathelo zokuvimbela zingasetshenziswa ngendlela efanele kuphela uma idatha enembile yezinga lokushisa nelomswakama ikhona.Idatha engalungile nokwamukelwa okubambezelekile ngenxa yephutha lomuntu kungaholela ezinqumweni ezingalungile.Ukuqapha ngamadivayisi ahlakaniphile afana ne-HengkoIzinzwa zezinga lokushisa lezinga lezimboni kanye nomswakamaingasiza ngempumelelo abasebenzisi ukukala idatha enembile.

Usenemibuzo futhi Uthanda Ukwazi Imininingwane Engeziwe Yokuqapha Umswakama Ngaphansi Kwezimo Zezulu Ezinzima, Sicela uzizwe Ukhululekile Xhumana nathi Manje.
