Kwenzekani lapho udaka loma?

Lapho udaka loma, inqubo eyaziwa ngokuthi i-hydration iyenzeka. I-Hydration ukusabela kwamakhemikhali phakathi kwamanzi nezinto zikasimende ku-ingxube yodaka. Izingxenye eziyinhloko zodaka, ezithola amanzi, zihlanganisa usimende, amanzi, futhi ngezinye izikhathi izithasiselo ezengeziwe noma izixube. Inqubo yokomisa ibandakanya izigaba ezibalulekile ezilandelayo:

1. Ukuxuba nokusebenzisa:
   • Ekuqaleni, udaka luxutshwa namanzi ukuze kwakheke inhlama esebenzayo. Lokhu kunamathisela bese kusetshenziswa ezindaweni ezihlukile zezinhlelo zokusebenza zokwakha, njengokubeka izitini, ukufakwa kwamathayela, noma ukuhlinzeka.
2. Ukusabela kweHydration:
   • Uma selusetshenzisiwe, udaka lubhekana nokusabela kwamakhemikhali okwaziwa ngokuthi i-hydration. Lokhu kusabela kuhlanganisa izinto zikasimende odakeni olubopha amanzi ukuze zenze ama-hydrate. Izinto zikasimende eziyinhloko ezidakamizweni eziningi yi-Portland Cement.
3. Isilungiselelo:
   • Njengoba ukusabela kwe-hydration kuqhubeka, udaka luqala ukusetha. Isilungiselelo sisho ukuqina noma ukuqina kodaka lodaka. Isikhathi sokusetha singahluka ngokusekelwe ezicini ezifana nohlobo lukasimende, izimo zemvelo, nokuba khona kwezithasiselo.
4. Ukwelapha:
   • Ngemva kokumiswa, udaka luyaqhubeka nokuthola amandla ngenqubo ebizwa ngokuthi ukwelapha. Ukwelapha kuhilela ukugcina umswakama owanele ngaphakathi kodaka isikhathi eside ukuze uvumele ukuqedwa kokusabela kwe-hydration.
5. Ukuthuthukiswa kwamandla:
   • Ngokuhamba kwesikhathi, udaka luzuza amandla alo aklanyelwe njengoba ukusabela kwe-hydration kuqhubeka. Amandla okugcina athonywa izici ezifana nokwakheka kwengxube yodaka, izimo zokwelapha, kanye nekhwalithi yezinto ezisetshenziswayo.
6. Ukomisa (Ukuhwamuka komhlaba):
   • Ngenkathi ukusetha kanye nezinqubo zokuphulukisa ziqhubeka, ubuso bodaka bungase bubonakale bomile. Lokhu kungenxa yokuhwamuka kwamanzi kusuka phezulu. Kodwa-ke, kubalulekile ukuqaphela ukuthi ukusabela kwe-hydration nokuthuthukiswa kwamandla kuyaqhubeka ngaphakathi kodaka, noma ngabe ubuso bubonakala bomile.
7. Ukuqedwa kwe-Hydration:
   • Iningi lokusabela kwe-hydration kwenzeka ezinsukwini ezimbalwa zokuqala kuya emasontweni ngemuva kokufakwa. Nokho, inqubo ingase iqhubeke ngenani eliphansi isikhathi eside.
8. Ukuqina Kokugcina:
   • Uma ukusabela kwe-hydration sekuphelile, udaka lufinyelela isimo salo sokugcina sokuqina. Izinto eziwumphumela zinikeza ukwesekwa kwesakhiwo, ukunamathela, nokuqina.

Kubalulekile ukulandela izinqubo ezifanele zokuphulukisa ukuze uqinisekise ukuthi udaka luthola amandla alo aklanyelwe kanye nokuqina. Ukomisa ngokushesha, ikakhulukazi phakathi nezigaba zokuqala ze-hydration, kungaholela ezindabeni ezinjengamandla ancishisiwe, ukuqhekeka, nokunamathela okubi. Umswakama owanele ubalulekile ekuthuthukisweni okugcwele kwezinto zikasimende odakeni.

Izici ezithile zodaka olomisiwe, okuhlanganisa amandla, ukuqina, nokubukeka, zincike ezintweni ezifana nedizayini yengxube, izimo zokuphulukisa, kanye nezindlela zokufaka isicelo.
