Ukukhutshwa kwamanzi kuyisisombululo esiphezulu sokukhusela izindlu zokuhlala ukusuka ekungeneni kwomswakama kwiindonga zokubamba. Yenziwe ngesiseko samente kunye nesihlabathi ngokusetyenziswa kwesongezo sokungenwa kwamanzi i-chloride ye-ferric, esinobuninzi obuninzi, lo mxube uhlukaniswe ngamandla okwandiswa kwe-hydrophobicity.
Kwakhona, iqondo eliphezulu lokumelana nokunyamezela lufezekiswa kukuba i-plaster yokukhupha amanzi iquka uhlobo oluthile lwesamente, i-mineral filler kunye ne-polymmer modifier, zonke izixhobo azizona zityhefu kwaye azichaphazeli impilo yabantu.
Olu hlobo lweplasita lusetyenziselwa ukugqiba iindonga kumagumbi apho kukho ukuhlamba okuphezulu, njengendawo yokuhlambela, igumbi lokubhukuda , igumbi elingaphandle , iplastiki, ngomsebenzi wefesade.
Ukufakwa kwamanzi okungenwa kwamanzi ngamanzi amacwecwe kufanelekile ukugqiba izindonga zitena, ilitye, ikhonkrit, inomlinganiselo ophezulu wokunamathela kwezi zinto. Ukusetyenziswa kweplasta kusetyenziswa emva kweenyanga ezi-4-6 zokusebenza zesakhiwo, xa kuqhutyelwa i-shrinkage.
Iindidi zokubeka amanzi ngamanzi
Kukho iintlobo ezintathu ze-plaster zokungenwa kwamanzi, eziquka imixube eyahlukeneyo:
- isanti-samente, eneemfuno ezizodwa ezivela kwiipolymers, ezenza ukuba kunyuka kwamanzi;
- i-asphalt plaster, ephethe i-mastic ebandayo okanye eshushu, isetyenziswe kwiziqendu eziliqela;
- ukukhupha i-asphalt yokungena kwamanzi, okuyi-mastic eshushu, ekugqibeleni igutywe nge-cement screed.
Ezi zisombululo kunye nokuxutywa kwamanzi zingasetyenziselwa zombini kwiinkqubo zokuqala zokwakha nakwiimigangatho yokugqibela. Ngokuxhomekeke ekubunjweni kwamacandelo afakwe kwi-plaster yokungenwa kwamanzi, ingasetyenziswa zombini phakathi kwesakhiwo sokuhlala kunye nangaphandle.
