Ubukhulu betheku lwenkinthuubonacrucial factor ekuthatheni amandla nokusebenza kwekonkrithi ngokuhamba kwesikhathi. Ukufakwa kwe-slag cement, umkhiqizo ovela enqubweni yokwakha insimbi, kungaba nomthelela omkhulu kulezi zinga zokwakheka. Le ndatshana ihlola umthelela we-slag cement ekwakhekeni kwekonkrithi, inikeza ukuqonda kwemikhawulo yayo kanye nezinto okufanele zicatshangwe.
Ubude bokwakha isilinganiso sokusebenza kwemvuthwandoko ye-siment, ethinta ngqo amandla nokuqina kokwakha. Kuvamise ukukalwa kusetshenziswa indlela yokuhlola ubude, ehlobisa umlando wezinga lokushisa nesikhathi sokuzuza amandla.
I-slag cement, eyaziwa nangokuthi i-ground granulated blast-furnace slag (GGBFS), iyimpahla ehlobene ne-cement (SCM) esetshenziselwa ukuthuthukisa izakhiwo ze-concrete. Ikhiqizwa ngokusheshisa ukushisa kwe-slag yensimbi ebhujiswa ephuma ebhakedeni, bese ibhakwa ibe uthuli oluthambile.
Ukufakwa kwe-slag cement ezixubheni ze-concrete kungashintshela ezingeni zokuvuthwa ngenxa yezici zayo ezihlukile kanye nezici zokuhlanganiswa.
– I-cement ye-slag ivamise ukuba nesivinini sokuhlanganisa sokuqala esinokuthula uma kuqhathaniswa ne-ordinary Portland cement (OPC).
– Lokhu kungaholela ekutholeni amandla okuqala okwakhiwa ngemuva.
– I-cement ye-slag iyaqhubeka nokuhlanganisa amanzi isikhathi eside, iphumelele ekwandiseni amandla ngaphezu kwesigaba sokuqala sokwelapha.
– Lokhu kungaholela kumandla aphezulu kwesikhathi eside.
– I-slag cement ikhiqiza ukushisa okuncane ngesikhathi sokuhlanza, okungasiza ezinhlelweni ezinkulu ze-concrete ukunciphisa ukuvunguza kwesikhumba.
- Izinga lokwakheka kwe-slag cement concrete libonakaliswa kakhulu ekushintsheni kwemvelo, lidinga ukuqapha ngokucophelela ezimweni zezulu ezahlukahlukene.
Lapho usebenzisa isamente ye-slag emixekeni ye-concrete, kufanele kubhekwe izinto eziningi ezinhle ukuze kuthuthukiswe ubudala nokusebenza.
I-slag cement ingaba nomthelela omkhulu ezingeni lokuphila kwe-concrete, inikeza izinselelo kanye nezinzuzo. Ngokuqonda umthelela wayo ekuhlanganiseni kwamanzi nokukhathazeka kokushisa, onjiniyela nabakhi bangathuthukisa imix yezinhlaka ze-concrete ukuze kuthuthukiswe ukusebenza nokusimama. Ukwehlisela kahle, izindlela zokwelapha, kanye nokubheka kubalulekile ukuze kuzuze amandla aphelele e-slag cement ezinhlelweni ze-concrete.
