Udaka olusetyenziswa kakhulu ludaka olutyabekayo, udaka oluxhathisa ukuqhekeka kunye nodaka lwemasonry.Umahluko wabo umi ngolu hlobo lulandelayo:
Udaka oluxhathisa ukuqhekeka:
Ludaka olwenziwe nge-agent echasene nokuqhekeka eyenziwe nge-polymer lotion kunye ne-admixture, i-samente kunye nesanti kumlinganiselo othile, onokuhlangabezana ne-deformation ethile kwaye igcine kungekho kuqhekeka.
I-crack resistant mortar yinto egqityiweyo, enokusetyenziswa ngokudibanisa amanzi kunye nokuxuba ngokuthe ngqo.Izinto ezigqityiweyo zokulwa nokuqhekeka kodaka yisanti ecolekileyo, isamente kunye ne-anti crack agent.Izinto eziphambili ze-anti-cracking agent luhlobo lwe-silica fume, olunokuthi luzalise ii-pores phakathi kweengqungquthela ze-samente, ii-gel ze-gel kunye neemveliso ze-hydration, kwaye ziphendule nge-alkaline oxide magnesium ukwenza iigels.
Udaka lokutyabeka:
Udaka olufakwe kumphezulu wezakhiwo kunye namacandelo kunye nomgangatho wezinto ezisisiseko, ezinokukhusela ikhosi yesiseko kunye nokuhlangabezana neemfuno zokusetyenziswa, zingabizwa ngokudibeneyo njengodaka lokutyabeka (olukwaziwa ngokuba ngudaka lokutyabeka).
Ubume bodaka:
Isongezo sokupakishwa kwesakhiwo esibandakanya izinto zejeli (ngokuqhelekileyo isamente kunye nekalika) kunye ne-aggregate ecolekileyo (ngokuqhelekileyo isanti ecocekileyo yendalo).
Ukugcinwa kwamanzi kodaka kubhekiselele kubuchule bodaka ukugcina amanzi.Udaka olunokugcinwa kakubi kwamanzi luthanda ukopha kunye nokwahlula ngexesha lokuthuthwa kunye nokugcinwa, oko kukuthi, amanzi adada ngaphezulu kunye nesanti kunye nesamente ezantsi.Kufuneka ixutywe kwakhona ngaphambi kokusetyenziswa.
Zonke iintlobo zezifundo ezisisiseko ezifuna ukwakhiwa kodaka zinokufunxa okuthile kwamanzi.Ukuba ugcino lwamanzi lodaka luhlwempuzekile, kwinkqubo yodaka lodaka, okoko nje udaka oluxubeneyo olululo ludibana nebhloko okanye isiseko, amanzi aya kufunxwa ludaka olusele luxutyiwe.Kwangaxeshanye, amanzi aya kuba ngumphunga ukusuka kumphezulu wodaka olujongene nomoya, okukhokelela kumanzi angonelanga odaka ngenxa yokulahleka kwamanzi, okuchaphazela ukuhanjiswa kwesamente ngakumbi, okuchaphazela uphuhliso oluqhelekileyo lwamandla odaka, okukhokelela kumandla ngakumbi. Amandla ojongano phakathi kodaka oluqina umzimba kunye nesiseko siba phantsi, okukhokelela ekuqhekekeni kodaka kunye nokuwa.Ngodaka olunokugcinwa kakuhle kwamanzi, i-cement hydration yanele ngokwaneleyo, amandla anokukhula ngokuqhelekileyo, kwaye inokubambisana kakuhle nekhosi yesiseko.
Ngoko ke, ukwandisa ukugcinwa kwamanzi omdaka akuncedi nje kuphela ukwakhiwa, kodwa ukwandisa amandla.
