Udaka olusetshenziswa kakhulu yi-plastering mortar, udaka olumelana nokuqhekeka kanye nodaka olusebenzisa ubumba. Umehluko wabo umi kanje:
Udaka olumelana nokuqhekeka:
Luyi-mortar eyenziwe nge-anticracking agent eyenziwe nge-polymer lotion kanye ne-additionture, i-samente kanye nesihlabathi ngesilinganiso esithile, engahlangabezana nokuguquguquka okuthile futhi ingagcini ukuqhekeka.
Udaka olumelana nokuqhekeka luyinto eqediwe, engasetshenziswa ngokufaka amanzi nokuxuba ngqo. Izinto eziqediwe zodaka olumelana nokuqhekeka yisihlabathi esihle, usimende kanye ne-anti-crack agent. Izinto eziyinhloko ze-anti-crack agent uhlobo lwe-silica fume, olungagcwalisa izimbobo phakathi kwezinhlayiya zesamente, lwakhe amajeli ngemikhiqizo yokufutha, futhi luphendule nge-alkaline magnesium oxide ukuze lwakhe amajeli.
Ukufaka iplasta ngodaka:
Udaka olusetshenziswa ebusweni bezakhiwo nezingxenye kanye nobuso bezinto eziyisisekelo, olungavikela isisekelo futhi luhlangabezane nezidingo zokusetshenziswa, lungabizwa ngokuthi udaka oluplastayo (olwaziwa nangokuthi udaka oluplastayo).
Ukwakhiwa ngodaka:
Isithasiselo sokufaka i-gel esakhiweni (ngokuvamile usimende kanye ne-lime) kanye ne-aggregate encane (ngokuvamile isihlabathi esincane semvelo).
Ukugcinwa kwamanzi kwesimende kubhekisela ekhonweni lesimende lokugcina amanzi. Isimende esinokugcinwa kwamanzi okuncane sivame ukopha nokuhlukaniswa ngesikhathi sokuthuthwa nokugcinwa, okungukuthi, amanzi ayantanta ngaphezulu bese isihlabathi nesimende sicwila ngaphansi. Kumelwe siphinde sixutshwe ngaphambi kokusetshenziswa.
Zonke izinhlobo zezindawo eziyisisekelo ezidinga ukwakhiwa kwe-mortar zinokumuncwa kwamanzi okuthile. Uma ukugcinwa kwamanzi kwe-mortar kukubi, enkambisweni yokufakwa kwe-mortar, inqobo nje uma i-mortar exubile ekulungele ixhumana ne-block noma i-base course, amanzi azomuncwa yi-mortar ekulungele. Ngesikhathi esifanayo, amanzi azophuma ebusweni be-mortar ebheke emoyeni, okuholela ekutheni amanzi anganele e-mortar ngenxa yokulahlekelwa amanzi, okuthinta ukumuncwa okuqhubekayo kwe-samente, okuthinta ukuthuthukiswa okuvamile kwamandla e-mortar, okubangela amandla. Ikakhulukazi, amandla okuxhumana phakathi komzimba we-mortar oqinile ne-base aba phansi, okuholela ekuqhekekeni nasekuweni kwe-mortar. Ku-mortar enokugcinwa kwamanzi okuhle, ukumuncwa kwe-samente kwanele, amandla angakhula ngokujwayelekile, futhi angahlangana kahle ne-base course.
Ngakho-ke, ukwandisa ukugcinwa kwamanzi kwe-mortar akugcini nje ngokusiza ekwakheni, kodwa futhi kwandisa amandla.
