Ingxoxo ngezinto ezithinta uketshezi lodaka

Ukluza uketshezi, luvame ukubizwa ngokuthi ukusebenza kwalo noma ukungaguquguquki, kuyindawo ebalulekile ethinta izici ezahlukahlukene zokwakha, okubandakanya ukubekwa kalula, ukuhlanganiswa, nokuqeda. Izici eziningana zithonya uketshezi lodaka, futhi ukuqonda lezi zinto kubalulekile ukuze kufezekiswe ukusebenza kahle kumaphrojekthi wokwakha. Nansi ingxoxo kwezinye izinto ezibalulekile ezithinta uketshezi lukadaka:

1. Isilinganiso se-WAM-to-Binder Ukwandisa okuqukethwe kwamanzi kungathuthukisa ukusebenza ngokunciphisa ukubonwa kanye nokugeleza okuqhubekayo. Kodwa-ke, amanzi amaningi aholela ekuhlukaniseni, ukopha, kanye namandla encishisiwe, ngakho-ke kubalulekile ukuze ulondoloze isilinganiso esifanelekile samanzi ukuze-mbinder for fluidity ngaphandle kokuyekethisa ukusebenza kodaka.
2. Uhlobo nokufakwa kweziqu ze-aggregates: uhlobo, usayizi, ukwakheka kanye neziqu zokuhlanganisa ezisetshenziswa kudaka zithinta izakhiwo zalo ze-rheologity ne-fluologity yayo. Ama-aggregates amahle, anjengesihlabathi, athuthukise ukusebenza ngokugcwalisa izikhala nezinhlayiya zokuthambisa, ngenkathi ama-coarse aggregates ahlinzeka ngokuqina namandla. Ama-aggregate ahlelwe kahle anokusatshalaliswa okulinganiselayo kwamasayizi ayizinhlayiya angathuthukisa ukupakisha ukugcwala kanye nokugeleza kodaka, okuphumela ekuthuthukiseni uketshezi kanye nokuhlangana.
3. Ukusatshalaliswa kosayizi wezinhlayiyana Izinhlayiya ezinhle zingagcwalisa izikhala phakathi kwezinhlayiya ezinkulu, zinciphisa ukumelana nengxabano kanye nokwenza ngcono ukugeleza. Ngakolunye uhlangothi, ukuhlukahluka okubanzi ngosayizi wezinhlayiyana kungaholela ekuhlukaniselweni kwezinhlathihla, ukungasebenzi kahle, futhi kwehlise uketshezi.
4. I-Chemical Admixturetures: Ama-Admixtures anamakhemikhali, afana nokunciphiswa kwamanzi, amapulasitiki, kanye nama-superplastifizer, angathinta kakhulu uketshezi lodaka ngokuguqula izakhiwo zalo ze-rhelogical ngokushintsha izakhiwo zalo ze-rhelogical ngokushintsha izakhiwo zalo ze-rhelogical ngokuguqula izakhiwo zalo ze-rheological ngokushintsha izakhiwo zalo ze-rhelogical ngokushintsha izakhiwo zalo zembongo. Amanzi anciphisayo anciphisa okuqukethwe kwamanzi okudingekayo ukuze kuncishiswe ukunqwabelana, ukuthuthukisa ukusebenza ngaphandle kokuyekethisa amandla. Amapulasitiki athuthukisa ukubumbana futhi anciphise ukubonakala, kanti ama-superplastizer anikeza ukugeleza okuphezulu nezakhiwo ezizimele, ikakhulukazi ngodaka ozimizayo.
5. Uhlobo lwe-Binder nokwakheka: Uhlobo nokwakheka kwama-linders, njengokwenza usimende, lime, noma inhlanganisela yalo, ukuthonya isikhathi se-hydration, ukusetha isikhathi, kanye nokuziphatha kwembongo. Izinhlobo ezahlukene zikasimende (isib. I-Portland cement, usimende oxutshwe) kanye nokwenza usimende ongezelelweyo (isib.
6. Inqubo Yokuxuba Nemishini: Inqubo yokuxuba kanye nemishini esetshenziselwa ukulungiselela udaka kungaba nomthelela omanzini kanye ne-homogeneity. Amasu Ofanele Ukuxuba, okubandakanya isikhathi esifanele sokuxuba, isivinini, kanye nokulandelana kokungezwa kwezinto zokwakha, kubalulekile ukuze kufinyelelwe ukuhlakazwa okufanayo kwezithako kanye nezici zembongo ezingaguquki. Ukuxuba okungafanele kungaholela ekutheni i-hydration engenele, ukuhlukaniswa kwezinhlayiya, nokusatshalaliswa okungafani kwama-admixture, okuthinta uketshezi nokusebenza kodaka.
7. Izimo zezemvelo: Izici zezemvelo ezinjengokushisa, umswakama, kanye nesivinini somoya kungathonya uketshezi lodaka ngesikhathi sokuxuba, ukuthuthwa nokubekwa. Amazinga okushisa aphezulu asheshisa i-hydration nokusetha, ukunciphisa ukusebenziseka kanye nokwandisa ingozi yokuqhekeka kwepulasitiki. Amazinga okushisa aphansi angabuyisa ukusetha futhi anciphise uxhaso, edinga ukulungiswa ukuze axube ubukhulu nemithamo yokuhlanganiswa ukuze alondoloze ukukhiqizwa okufisayo.

U-fluity of motar uthonywa inhlanganisela yezinto ezihlobene nezinto zokwakha, ukuxuba design, izinqubo zokuxuba, kanye nezimo zemvelo. Ngokucabanga ngokucophelela lezi zinto nokwenza kahle ukuxubana, ochwepheshe bezokwakha bangathola udaka no-fluidity olufunayo, ukungaguquguquki, kanye nokusebenza kwezicelo ezithile nezidingo zephrojekthi.
