Ho Tiisa Bokamoso: Ho Fuputsa Lihlomathiso Tse Ncha ho Kaho ea Konkreite
Ho aha meaho ea konkreite e tšoarellang le e sebetsang hantle ho itšetlehile haholo ka khetho ea li-additives, tse bapalang karolo ea bohlokoa ho ntlafatseng thepa ea konkreite. Li-additives tsena, joalo ka molora oa fofa, cenospheres, perlite e atolositsoeng, li-microspheres tsa khalase tse se nang letho, likhoele tsa konkreite le lisebelisoa tse fokotsang metsi, li fetola indasteri ea kaho ka ho ntlafatsa metsoako ea konkreite le metsoako. Sengoliloeng sena se ikemiselitse ho hlahloba thepa le mesebetsi ea li-additives tsena tse ncha, ho totobatsa tšusumetso ea tsona e kholo ts'ebetsong ea konkreite.
Fofa molora , sehlahisoa sa mashala a tukang, se sebelisoa haholo tlhahiso ea konkreite ka lebaka la thepa ea eona ea pozzolanic. E matlafatsa matla a konkreite, ho tšoarella, le ho sebetsa ha e ntse e fokotsa mocheso oa hydration. Ka ho fetola karolo ea samente,fofa molora e khothalletsa mekhoa ea kaho e tsitsitseng ka ho fokotsa carbon footprint. Boholo ba eona bo botle ba likaroloana le sebopeho sa spherical se matlafatsa letsoalo la konkreite ea ho paka, e lebisang ho fokotseng ho kenella le ho ntlafala ho hanyetsa maemo a tikoloho le bahlaseli ba lik'hemik'hale.
Li-cenospheres , li-microspheres tsa ceramic tse bobebe tse bobebe tse nkiloeng moloreng oa lintsintsi, li ntse li tsejoa ka ho eketsehileng e le li-additives tse ngata haholo tlhahisong ea konkreite. Boima ba bona bo tlase le sebopeho sa spherical se kenya letsoho ho fokotsa sekhahla sa konkreite, se etsa hore e tšoanelehe bakeng sa lits'ebetso tse hlokang meaho e bobebe. Ho feta moo,cenospheres ntlafatsa thepa ea konkreite ea ho kenya mocheso oa mocheso, ho e etsa e loketseng merero ea kaho e baballang matla.
Perlite e atolositsoeng , khalase ea tlhaho ea seretse se chesang, e susumetsa haholo litšobotsi tsa konkreite. Litšobotsi tsa eona tse bobebe le tse sireletsang mocheso li fokotsa boima ba konkreite ha li ntse li matlafatsa ho hanyetsa mollo le ts'ebetso ea mocheso. Ho kenyelletsaperlite e atolositsoeng metsoako ea konkreite e fella ka meaho e tšoarellang le e baballang matla, e leng se etsang hore e be khetho e ratoang bakeng sa mesebetsi ea moaho e tsitsitseng.
Li-microsphere tsa khalase tse se nang letho , likaroloana tse entsoeng ka boima bo bobebe tse nang le matla a phahameng a ho hatella, li fetola theknoloji ea konkreite. Li-microspheres tsena li ntlafatsa ts'ebetso ea motsoako oa konkreite, li fokotsa bongata, 'me li ntlafatsa ho kenya letsoho mocheso. Sebōpeho sa tsona se chitja le mocheso o tlase oa mocheso li li etsa hore e be tse loketseng bakeng sa ho hlahisa konkreite e bobebe bo bobebe e sebetsang hantle ka ho tšoarella le matla a matla.
Likhoele tsa konkreite , ho kenyeletsoa litšepe, tsa maiketsetso, le mefuta e fapaneng ea tlhaho, li sebetsa joalo ka litlatsetso tse matlafatsang matla a konkreite le ho tiea. Likhoele tsa tšepe li matlafatsa khanyetso ea mapetso a konkreite le ho ductility, ho etsa hore e tšoanelehe bakeng sa lits'ebetso tsa indasteri le tsa meaho.Likhoele tsa maiketsetso , tse kang polypropylene le nylon, li matlafatsa khanyetso ea phello ea konkreite le ho tšoarella, haholo-holo libakeng tse nang le sephethephethe se phahameng. Likhoele tsa tlhaho tse kang jute le coconut li fana ka likhetho tse matlafatsang ha li ntse li fokotsa tlhahiso ea khabone tlhahiso ea konkreite.

Ka ho hasanya likaroloana tsa samente ka katleho, li-agents tsa phokotso ea metsi li nolofalletsa tlhahiso ea konkreite e matla e nang le metsi a fokotsehileng. Sena se lebisa ho tiisetso e ntlafetseng, ho fokotsa ho phunyeletsa, le ho ntlafala ha bokaholimo, ho etsa hore e be karolo ea bohlokoa mahlaleng a sejoale-joale a konkreite.
Ka bokhutšoanyane, ts'ebeliso e ncha ea lisebelisoa tsa konkreite, ho kenyeletsoa molora oa lintsintsi, cenospheres, perlite e atolositsoeng, li-microspheres tsa khalase tse se nang letho, likhoele tsa konkreite le lisebelisoa tse fokotsang metsi, li fetola mekhoa ea kaho ea konkreite. Li-additives tsena ha li ntlafatse thepa ea motsoako oa konkreite feela empa hape li kenya letsoho mekhoeng ea kaho e tsitsitseng le e baballang matla.
