I-METYOKIRTECT 1: I-Concrete Admixtures isetshenziswa ngqo ngaphandle kokuhlolwa
Ngaphambi kokwakhiwa kokhonkolo, amayunithi wokwakha namayunithi wokugada ahlala athumela usimende, isihlabathi, itshe kanye neminye imikhiqizo yokwakha izinto zokwakha ezihlolweni zokuhlola ukuze ihlolwe ngama-batchs ngokuya ngokuhlolwa kokusebenza kwama-admixtures. Eqinisweni, kunezinhlobo eziningi ze-comscrete admixtures, futhi zonke zinamazinga afanelekile. Ikhwalithi yokusebenza kwabo ithinta ngqo iqhaza labo kukhonkolo, njengosayizi wenani lokuncipha kwamanzi, inani le-chloride ion okuqukethwe, njll.
Umumo 2: Ama-comcrete admixture asetshenziswa ngokunganquvithi ngaphandle kokucabanga ngesimo sangempela sephrojekthi
1. Inhloso yokusebenzisa kufanele ibhekwe lapho ukhetha ama-admixture. Lapho ukhetha ama-admixtures, kufanele anqunywe ngokuhlolwa kokuxutshwa kwesilingo ngokususelwa ezintweni zokwakha kanye nemibandela yokwakha. Ama-admixtures ahlukahlukene anezimpawu zawo. Lapho besebenzisa, kufanele basuselwe kwizici ze-admixtures kanye nenhloso yokusebenzisa, njengokucabanga kwezinkomba eziphelele njengokugcina usimende, ukuthuthukisa ukusebenza kokhonkolo, okungukuthi ukusheshisa imali yokuhlanganiswa okuzosetshenziswa ngokuqhathanisa nobuchwepheshe nakwezomnotho.
2. Ukuhlaziywa kokusetshenziswa kwe-admixtures kuma-concretes amaningana (1) inhloso yokusebenzisa ama-admixtures kukhonkolo ongangeni manzi ukuthuthukisa ukungakhululeki kukakhonkolo. Ukwenza ngcono ukungahambisani kukakhonkolo, ukhiye ukunciphisa ama-pores ngaphakathi kokhonkolo, vimba indlela yokuvuza, bese usebenzisa ukuncishiswa kwamanzi kanye nama-ejenti okufaka umoya. . Ukusetshenziswa kwamanzi okubeka kancane kwamanzi kungahlangabezana nalezi zidingo ezingenhla, okungukuthi, ukusetha kancane futhi kunciphise ukukhuphuka kwezinga lokushisa ngesikhathi senqubo yokwenza ngokhonkolo, ngaleyo ndlela kuthuthukise ikhwalithi kakhonkolo. . Ngakho-ke, inhloso yokusebenzisa ama-admixtures ukulungiselela ukhonkolo onamandla aphezulu, yehlisa isisindo sesakhiwo, futhi usebenzise ngempumelelo ingcindezi yemigoqo yensimbi ephezulu. Kungcono ukusebenzisa ukunciphiswa kwamanzi okusebenza kahle, okunganciphisa kakhulu ukusetshenziswa kwamanzi kweyunithi futhi kuthuthukise amandla kakhonkolo.
