Isimo Sezulu Esibandayo
Ngaphansi kwezimo zezulu ezibandayo, kugcizelelwa ukuvimbela ukubanda kwezingane ezincane kanye nokulawula amazinga okushisa asendaweni ngesikhathi sokwelashwa ukuze kuthuthukiswe ukuthuthukiswa kwamandla.Ukuphatha izinga lokushisa le-base slab ngesikhathi sokubekwa kanye nokwelashwa kwe-topping slab kungase kube isici esiyinselele kakhulu esihlobene nokubanda kwesimo sezulu esibandayo.
I-base slab cishe izoba nesisindo esikhulu kune-topping slab.Ngenxa yalokho, izinga lokushisa le-base slab lizoba nomthelela omkhulu ekubekweni kwe-topping slab.Ama-topping slabs akufanele abekwe ku-slab yesisekelo esiqandisiwe njengoba izinga lokushisa le-base slab lizodonsa ukushisa kude nengxube ye-topping entsha.

Uma kubanda iheater ekhipha umoya kufanele ibekwe ngaphandle kwesakhiwo ngesikhathi sokubekwa kwento engaphezulu.
Izincomo zemboni ukuthi i-base slab kufanele igcinwe ezingeni lokushisa okungenani elingu-40 F ngesikhathi sokubekwa kanye nokuphulukiswa kwe-topping ukuze kukhuthazwe ukugeleza kwamanzi, ukuthuthukiswa kwamandla, nokugwema ukubanda kwezingane ezincane.Ama-cooler base slabs angase abambezele isethi ye-topping mix, andise isikhathi sokopha kanye nemisebenzi yokuqeda.Lokhu kungase futhi kwenze i-topping ibe lula kwezinye izinkinga zokuqeda ezifana nokushwabana kwepulasitiki noqweqwe lwangaphezulu.Noma nini lapho kungenzeka, sincoma ukushisisa i-base slab ukuze uvimbele ukubanda futhi unikeze izimo zokuphulukisa ezamukelekayo.
Izingxube ze-topping sezulu ezibandayo zingaklanywa ukusiza ukulungisa imiphumela yezinga lokushisa le-ambient kanye nesisekelo se-slab ngesikhathi sokusetha.Shintshanisa izinto zikasimende ezisebenza kancane ezisabelayo ngosimende oqondile, sebenzisa usimende Wohlobo lwe-III, futhi usebenzise izixube ezisheshayo (cabanga ngomthamo okhulayo njengoba ukubekwa kuqhubeka ukuze ugcine isikhathi sokusetha esilinganayo).
Ukulungisa umswakama isisekelo esilungisiwe ngaphambi kokusibeka kungaba inselele esimweni sezulu esibandayo.Ukumanzisa ngaphambili i-base slab akunconywa uma kulindeleke ukubanda.Izigqoko eziningi, nokho, zakhiwe kuma-slabs akhona lapho kwakhiwa khona futhi kuvalelwe.Ngakho-ke, ukwengeza ukushisa endaweni lapho kuzobekwa khona i-topping ngokuvamile akuyona inselele kunesikhathi sokwakhiwa kokuqala kwe-superstructure kanye ne-base slab.
Njengokumanzisa ngaphambili kwesisekelo, ukuphulukiswa okumanzi kufanele futhi kugwenywe uma kulindeleke ukubanda.Kodwa-ke, ama-toppings amancane aboshwe azwela kakhulu ekomisweni kusenesikhathi ngenkathi amandla ebhondi ekhula.Uma i-topping eboshiwe yoma futhi incipha ngaphambi kokuthuthukisa amandla ebhondi anele esisekelweni, amandla okugunda angabangela ukugqama ukuthi kunciphe kusukela kusisekelo.Uma i-delamination seyenzekile isencane, i-topping ngeke ibuyisele isibopho ku-substrate.Ngakho-ke, ukuvimbela ukomiswa kwasekuqaleni kuyisici esibalulekile ekwakhiweni kwe-toppings eboshiwe.
