Yintoni imixube Concrete? .

(Imixube yeConcrete yoLwakhiwo lweMozulu ebandayo)

Cinga ngemixube ekhonkrithi efana namacandelo akhethekileyo esityeni. Bafumana ingxubevange kwibhetshi yekhonkrithi. Umsebenzi wabo kukutshintsha indlela ikhonkrithi eziphatha ngayo. Oku kubaluleke kakhulu xa kusakhiwa kwimozulu ebandayo. Ikhonkrithi eqhelekileyo ayifani nokubanda. Inokuba ngumkhenkce phambi kokuba yomelele. Inokuseka kwakhona ngokucothayo. Oku kungonakalisa wonke umsebenzi. Imixube yasebusika iyayikhathalela le miba. Bancedisa ukuseta ikhonkrithi ngokufanelekileyo naxa kubanda ngaphandle. Iintlobo eziqhelekileyo ziquka i-accelerators, iiantifreeze, kunye nabameli be-air-entraining. Ii-accelerators zikhawulezisa ixesha lokuseta. Ii-antifreezes zehlisa into ebandayo yamanzi kumxube. Ii-air-entrainers zivelisa amaqamza amancinci. La maqamza abonelela ngommandla wamanzi omkhenkce ukuze anyuke ngaphandle kokucalula ikhonkrithi. Ngoko, ezi zidibaniso zifana nabancedisi bekhonkrithi. Benza ukuba kube nzima ngokwaneleyo ukulawula ingqele.

Kutheni iiMfuneko zaseBusika zifuna iiMixube eziKhethekileyo? .

Ukwakha ngekhonkrithi ngexesha lasebusika kunzima. Ngoba? Ngenxa yokuba ukuphiliswa kwekhonkrithi kukusabela kwekhonkco. Izixhobo zokufudumala le mpendulo zenzeka ngokukhawuleza. Ukubanda kuyayithothisa. Cinga ngokupheka amaqebengwana kwi-oveni epholileyo. Abayi kujika balunge. Ithelekiseka nekhonkrithi. Ukuba umxube ubanda kakhulu, amanzi angaphakathi anokuba ngumkhenkce. Amanzi abandayo ayanda. Olu lwandiso lunokunyanzelisa ikhonkrithi yahlukane. Ufumana amanqaku ahlukeneyo kunye nobuthathaka. Kwakhona ukuba ayibanda, ukuseta okudangeleyo ukuziphatha kakubi. Ikhonkrithi ihlala ithambile ixesha elide. Oku kuthetha ukuba inokwenzakala ngokulula. Abasebenzi banokuyinyathela ngaphambi kwexesha. Okanye iqabaka inokuyihlasela ngobusuku. Ukulibaziseka kubiza imali ngokunjalo. Iiprojekthi zithatha ixesha elide ukugqiba. Ii-admixtures zasebusika ezizodwa zilungisa le miba. Zikhusela ikhonkrithi. Bayinceda ukuba ifumane amandla ngokukhawuleza. Zikhusela umonakalo womkhenkce. Ukuzisebenzisa kubonisa ukuba umsebenzi wakho wekhonkrithi awuyi konakaliswa yingqele. Ibalulekile kumgangatho ophezulu kunye nokhuseleko kunye nokhuseleko.

Zisebenza njani ezi zidibanisi? .

Imixube yasebusika ijongana nokubanda ngeendlela ezahlukeneyo. Ii-accelerator zifana nokunika ikhonkrithi amandla. Bakhawulezisa ukusabela kwemichiza eyenza ikhonkrithi ibe lukhuni. Icalcium chloride yayixhaphakile, kodwa iinketho zikhona ngoku ngenxa yemingcipheko yomhlwa. I-non-chloride accelerators isebenza kakuhle ngokunjalo. Bancedisa iqoqo lekhonkrithi ngokukhawuleza ngaphambi kokuba kubanda kunokudala ubunzima. Imixube yeAntifreeze isebenza ngeendlela ezahlukeneyo. Banciphisa into ebandayo yamanzi kumxube. Yicinge njenge-antifreeze kwiimoto zakho kunye neradiyetha yelori. Ithintela amanzi ekubeni abe ngumkhenkce nakubushushu obuphantsi. Oku kuthintela ukwanda okutshabalalisayo okubangelwa yingqele. I-admixtures yokungenisa umoya yongeza umaleko owongezelelweyo wokhuseleko. Baphuhlisa amaqamza omoya angenakubalwa kwikhonkrithi. If any water inside does freeze, la maqamza abonelela indawo yokwandisa phakathi. Oku kuphelisa uxinzelelo kwaye kunqande i-fractures ekuphuhliseni. Rhoqo, iikontraka zisebenzisa indibaniselwano yezi ntlobo. Oku kubonelela ngokhuseleko olungcono ngokuchasene neempembelelo ezigqithisileyo zasebusika.

Zisetyenziswa Phi? .

Uya kufumana imixube yekonkrithi yasebusika esetyenziswa kwimisebenzi emininzi yokwakha yasebusika. Cinga ngomsebenzi omkhulu wezixhobo. Amasebe ohola wendlela athembele kubo ngokuphuhlisa iibhulorho kunye neendlela unyaka wonke. Ukumisa ukwakhiwa kweendlela rhoqo ngexesha lasebusika akusebenzi. Ezi zidibaniso zivumela ukuba umsebenzi uqhubeke ngokukhuselekileyo. Ulwakhiwo lolunye usetyenziso olukhulu. Izakhiwo zifuna iziseko eziqinileyo. Ukuhlehlisa umsebenzi wesiseko kude kube kusentwasahlobo kunokumisa yonke iprojekthi. Ukusebenzisa imixube kwenza ukuba izakhiwo zifakwe nakwiinyanga ezibandayo. Izityalo ze-precast zekhonkrithi nazo ziyazisebenzisa. Ezi fektri zenza amacandelo ekhonkrithi afana neendonga okanye imisebe yezibane ngaphakathi. Nangona kunjalo amalungu afuna ukunyanga, rhoqo ngaphandle okanye kumagumbi angenakufudumala. I-Admixtures iqinisekisa ukuba ezi zinto ziphilisa ngokufanelekileyo nangona kubanda. Imisebenzi emincinci iyanceda nayo. Qwalasela iindlela zokuhamba, iindlela zokuhamba, okanye iindawo zepatio. Abanini bezindlu okanye iikontraka zinokufuna ukubeka ikhonkrithi emva kwexesha lonyaka. I-Admixtures inceda ezi ndawo zincinci ziphumelele. Naphi na apho ikhonkrithi idibana nomoya obandayo, le mixube ekhethekileyo idlala umsebenzi obalulekileyo.

Imibuzo Ebuzwa Rhoqo .

Leliphi iqondo lobushushu elibandayo endinokulibeka ikhonkrithi? Kuxhomekeke kakhulu kwimixube esetyenziswayo kunye neendlela zokukhusela ezifana nokugquma okanye izivalo ezishushu..
