Ishishini lemigangatho lichitha malunga ne-US$2.4 yebhiliyoni ngonyaka ukulungisa ukusilela komgangatho okunxulumene nokufuma. Nangona kunjalo, amayeza amaninzi anokujongana kuphela neempawu zokusilela okunxulumene nokufuma, hayi oyena nobangela.
Isizathu esiphambili sokungaphumeleli komgangatho ngumswakama ophuma kwikhonkrithi. Nangona ishishini lokwakha liye laqaphela ukufuma komhlaba njengonobangela wokusilela komgangatho, eneneni luphawu lwengxaki enzulu. Ngokujongana nale mpawu ngaphandle kokujongana nonobangela wengcambu, abachaphazelekayo bajongene nomngcipheko wokungaphumeleli okuqhubekayo komgangatho. Kwiminyaka embalwa edlulileyo, ishishini lokwakha liye lenza iinzame ezininzi zokusombulula le ngxaki, kodwa ngempumelelo encinci. Umgangatho wangoku wokulungisa wokugubungela i-slab nge-adhesive ekhethekileyo okanye i-epoxy resin isombulula kuphela ingxaki yomswakama ophezulu kwaye ungayihoyi ingcambu ye-concrete permeability.
Ukuze uqonde le ngcamango ngokucokisekileyo, kufuneka uqale uqonde inzululwazi esisiseko yekhonkrithi ngokwayo. Ikhompawundi yindibaniselwano eguquguqukayo yamacandelo adibanisa ukwenza i-catalytic compound. Le yindlela enye yokusabela kwemichiza eqala xa amanzi egalelwe kwizithako ezomileyo. Ukusabela ngokuthe ngcembe kwaye kunokutshintshwa ziimpembelelo zangaphandle (ezifana neemeko ze-atmospheric kunye nobuchule bokugqiba) nakweyiphi na indawo kwinkqubo yokusabela. Utshintsho ngalunye lunokuba nempembelelo embi, engathathi hlangothi okanye elungileyo ekungeneni. Ukuze kuthintelwe ezi meko ukuba zisilele, indlela enye yekhemikhali yokuchacha kufuneka ilawulwe. Iimveliso ezinokulawula le ntshukumo yeekhemikhali, ziphucule ukunyanzeliswa kwekhonkrithi, kwaye ziphelise ukugoba komgangatho kunye nokuqhekeka okunxulumene nokunyanga.
Ngokusekelwe kwezi ziphumo, i-MasterSpec kunye ne-BSD SpecLink yenze ulwahlulo olutsha kwiCandelo le-3, elichongiweyo njengokunyanga kunye ne-sealant, ukunciphisa ukukhutshwa komswakama, kunye nokungena. Olu lwahlulo olutsha lweCandelo 3 lunokufumaneka kwicandelo le-MasterSpec 2.7 kunye ne-intanethi ye-BSD SpecLink. Ukuze ufaneleke kolu didi, iimveliso kufuneka zivavanywe ngumntu wesithathu ozimeleyo waselebhu ngokuhambelana neendlela zovavanyo ze-ASTM C39. Olu luhlu alufanele ludideke kunye nayiphi na ifilimu eyenza ifilimu yokunciphisa ukukhutshwa komswakama, eyazisa imigca eyongezelelweyo yokudibanisa kwaye ayihambelani nemigangatho ephezulu yokusebenza yokuhlelwa kwe-permeation.
Iimveliso zolu didi lutsha azilandeli inkqubo yokulungisa yemveli. (Iindleko ezidlulileyo zangaphambili ubuncinane ubuncinane be-$ 4.50 / square foot.) Kunoko, kunye nesicelo sokutshiza esilula, ezi nkqubo zinokungena kwikhonkrithi, zinciphise i-matrix ye-capillary, kwaye zinciphise ukunyanzeliswa. I-permeability encitshisiweyo iphazamisa indlela evumela ukuba umswakama, umswakama, kunye ne-alkalinity ihanjiswe kumphezulu we-slab okanye i-bonding layer. Ngokususa ngokulula ukungaphumeleli komgangatho ngokupheleleyo, kungakhathaliseki ukuba luhlobo luni lomgangatho okanye i-adhesive, oku kuphelisa ixabiso eliphezulu lokulungiswa okuhambelana nomswakama ngenxa yokungaphumeleli komgangatho.
Enye imveliso kolu didi olutsha SINAK kaThixo VC-5, olawula permeability kunye nokuphelisa ukungaphumeleli umgangatho okubangelwa ukufuma, ukufuma, kunye alkalinity ekhutshwa ngekhonkrithi. I-VC-5 inika ukhuseleko olusisigxina ngomhla wokubekwa kwekhonkrithi, ukuphelisa iindleko zokulungisa, kunye nokutshintsha ukunyanga, ukutywinwa, kunye neenkqubo zokulawula ukufuma. Ngaphantsi kwe-1 USD/m². Xa kuthelekiswa neendleko eziqhelekileyo zokulungisa, i-VC-5 inokugcina ngaphezu kwe-78% yeendleko. Ngokunxulumanisa uhlahlo lwabiwo-mali lweCandelo 3 kunye neCandelo 9, inkqubo isusa uxanduva ngokuphucula unxibelelwano lweprojekthi kunye nocwangciso olusebenzayo. Ukuza kuthi ga ngoku, i-SIAK kuphela kwenkampani eye yaphuhlisa itekhnoloji edlula imigangatho ephezulu yoshishino kule ndawo.
