Kulwakhiwo lweendawo zokuhlala, ulwakhiwo lwekhonkrithi ubukhulu becala lwamkela inkqubo yangoku yamanzi. Nangona le ndlela ikhulile, ikwasebenzisa amandla amaninzi, ungcoliseko oluphezulu kunye nobuchwepheshe obuphantsi. "Kuqoqosho lwekhabhoni ephantsi", "isakhiwo esiluhlaza" iikhonsepthi ezivelayo ezinje ngesikhokelo, uhlengahlengiso lwendlela yolwakhiwo lweendawo zokuhlala, ukukhuthaza ushishino lwezindlu, uphuhliso lolwakhiwo lwezindlu olulungiselelweyo lube yinto engenakuphepheka yophuhliso lwezindlu zelizwe lethu ngokwamava abonisa ukuba xa kuthelekiswa nendlela yolwakhiwo lwekhonkrithi yesiqhelo, Ukonga amanzi kwisakhiwo esenziwe kwangaphambili ngama-80%, gcina imathiriyeli ngaphezu kwe-20%, ukunciphisa inkunkuma yokwakha malunga nama-80%, amandla abanzi. ukonga i-70%, ukunciphisa iindleko zokulondoloza malunga nama-95%. Kwangaxeshanye, indawo yokwakha ingancitshiswa ukuze kuphuculwe ukusebenza kakuhle kokusetyenziswa komhlaba.
Iimfuno zokusebenza ze-adhesive yokutywina kwisakhiwo esenziwe kwangaphambili
Ukubambelela yenye yezona zinto zibalulekileyo kwi-sealant. Kuyafana nakwizinto ezisisiseko ezisetyenziswa kwizakhiwo ezenziweyo. Okwangoku, ezininzi iiplati zePC ezisetyenziswa kwiimarike zenziwe ngekhonkrithi, ngoko ke kukho ukubambelela kakuhle kwi-concrete substrate yee-seams. Kwizinto eziphathekayo, ukunamathela kwe-sealant eqhelekileyo kumphezulu akulula ukufezekisa, oku kungenxa yokuba: (1) ikhonkrithi luhlobo oluthile lwezinto ezixubileyo, ukusabalalisa okungafaniyo kobukhulu bomngxuma kwaye akuhambelani ne-sealant adhesion; I-alkaline (2) ikhonkrithi ngokwayo, ngakumbi kwisiseko sezinto ezi-bibulous, inxalenye yezinto zealkaline ziya kufudukela kwi-sealant kunye ne-concrete interface yoqhagamshelwano, ngaloo ndlela ichaphazela ukunamathela; 3
