Udaka olusetshenziswa kakhulu udaka lokuplasta, udaka olungazwani nokuqhekeka kanye nodaka lwamatshe. Umehluko wabo umi kanje:
Udaka olumelana nokuqhekeka:
Iwudaka olwenziwa nge-anti cracking agent eyenziwe nge-polymer lotion ne-admixture, usimende nesihlabathi ngengxenye ethile, engahlangabezana nokuguqulwa okuthile futhi ingagcini ukuqhekeka.
I-crack resistant mortar yizinto eziqediwe, ezingasetshenziswa ngokungeza amanzi nokuxuba ngokuqondile. I-anti crack mortar material eqediwe isihlabathi esihle, usimende kanye ne-anti crack agent. Impahla eyinhloko ye-anti cracking agent iwuhlobo lwe-silica fume, engagcwalisa izimbotshana phakathi kwezinhlayiya zikasimende, yakha ama-gel anemikhiqizo ye-hydration, futhi isabela nge-alkaline magnesium oxide ukwenza ama-gel.
Udaka lokunamathisela:
Udaka olusetshenziswa phezu kwezakhiwo kanye nezingxenye kanye nangaphezulu kwezinto eziyisisekelo, ezingavikela inkambo eyisisekelo futhi zihlangabezane nezidingo zokusetshenziswa, zingabizwa ngokuhlangene ngokuthi udaka lokuplasta (olwaziwa nangokuthi udaka lokuplasta).
I-Mortar masonry:
Isengezo sokunqwabelaniswa kwesakhiwo esihlanganisa izinto zejeli (imvamisa usimende nomcako) kanye nesamba esihle (imvamisa isihlabathi esicolekile semvelo).
Ukugcinwa kwamanzi kodaka kubhekisela emandleni odaka okugcina amanzi. Udaka olungagcini kahle amanzi lujwayele ukopha nokuhlukaniswa ngesikhathi sokuthutha nokugcinwa, okungukuthi, amanzi antanta ngaphezulu nesihlabathi nosimende usinki ngezansi. Kufanele ihlanganiswe kabusha ngaphambi kokusetshenziswa.
Zonke izinhlobo zezifundo eziyisisekelo ezidinga ukwakhiwa kodaka zinokumuncwa okuthile kwamanzi. Uma ukugcinwa kwamanzi kodaka kungalungile, ngesikhathi sokumbozwa kodaka, inqobo nje uma udaka olulungile luthinta ibhulokhi noma inkambo yesisekelo, amanzi azomuncwa udaka oluxubile olulungile. Ngesikhathi esifanayo, amanzi azohwamuka ebusweni bodaka olubheke emkhathini, okuholela ekubeni kube namanzi anganele odaka ngenxa yokulahlekelwa kwamanzi, okuthinta ukugeleza okwengeziwe kukasimende, okuthinta ukuthuthukiswa okujwayelekile kwamandla odaka, okuholela emandleni Ikakhulukazi, amandla esixhumi esibonakalayo phakathi komzimba owenziwe lukhuni nodaka kanye nesisekelo siba phansi, okuholela ekuqhekekeni kodaka nokuwa. Ngodaka olunokugcinwa kahle kwamanzi, i-hydration ye-cement yanele ngokwanele, amandla angakhula ngokujwayelekile, futhi angakwazi ukuhlangana kahle ne-base course.
Ngakho-ke, ukwandisa ukugcinwa kwamanzi odaka akusizi nje kuphela ukwakhiwa, kodwa futhi kwandise amandla.
