Ikhonkrithi ekulungeleyo (RMC) iveliswa kwizityalo zokudibanisa njengoko kuchaziwe kwikhonkrithi emva koko idluliselwe kwiindawo zeprojekthi. Umxube wezityalo uthandwa kakhulu kunezityalo zomxube owomileyo. Kwizityalo zemixube emanzi, zonke izithako zekhonkrithi kubandakanya amanzi zixutywe kumxube ophakathi kwaye emva koko zigqithiselwe kwiindawo zeprojekthi ziitraki ze-agitator. Ngexesha lokuhamba, iilori zihlala zijikeleza nge-2 ~ 5 rpm ukunqanda ukuseta kunye nokwahlulahlula ikhonkrithi. Yonke imisebenzi yesityalo ilawulwa kwigumbi lokulawula. Izithako zekhonkrithi zilayishwe kumxube ngokoyilo lomxube. Uyilo oluxubeneyo lwekhonkrithi yindlela yokuvelisa imitha enye yekyubhi yekhonkrithi. Uyilo lokuxuba kufuneka lutshintshwe ngokwahluka kwe-gravity ethile yesamente, isilinganiselo esirhabaxa, kunye nomdibaniso ocolekileyo; Amazwe okufuma, njl njl. Umzekelo, ukuba ubunzima bomxhuzulane othe kratya bonyuswe, ubunzima bendibaniselwano erhabaxa kufuneka bunyuswe ngokufanelekileyo. Ukuba umndilili uqulethe inani elongezelelweyo lamanzi ngaphezulu kweemeko ezomileyo zomphezulu womhlaba, isixa sokuxuba amanzi kufuneka sincitshiswe ngokufanelekileyo. Kwizityalo ze-RMC, iinjineli zoLawulo loMgangatho kufuneka zenze uluhlu lokutshekisha ukuqinisekisa umgangatho wemveliso.
I-RMC inezibonelelo ezininzi ngaphezulu kokudityaniswa kwesiza. I-RMC (i) ivumela ulwakhiwo olukhawulezileyo, (ii) ukunciphisa iindleko ezinxulunyaniswa nomsebenzi kunye nokujonga, (iii) inolawulo oluphezulu lomgangatho ngolawulo oluchanekileyo nolwekhompyuter lwezinto zekhonkrithi, (iv) inceda ekunciphiseni inkcitho yesamente, (v) ngaphandle kongcoliseko, (vi) kunceda ukugqitywa kweprojekthi kwangoko, (vii) kuqinisekisa ukuzinza kwekhonkrithi, (viii) kunceda ekugcineni izixhobo zendalo, kwaye (ix) lukhetho olusebenzayo lokwakha kwindawo encinci.
Kwelinye icala, i-RMC inezithintelo: (i) ixesha lokuhamba ukusuka kwisityalo ukuya kwindawo yeprojekthi ngumba obaluleke kakhulu njengeeseti zekhonkrithi ezinexesha kwaye azinakusetyenziswa ukuba iiseti zekhonkrithi ngaphambi kokugalela esizeni, (ii) iilori ze-agitator ukuvelisa izithuthi ezongezelelekileyo ezindleleni, kwaye (iii) iindlela zingonakala ngenxa yomthwalo onzima othwelwe ziilori. Ukuba ilori ithwala i-9 yee-cubic metres zekhonkrithi, ubunzima bebonke belori bungalunga iitoni ezingama-30. Nangona kunjalo, kukho iindlela zokunciphisa ezi ngxaki. Ngokusebenzisa umxube wemichiza, ixesha lokusetwa kwesamente linokuqhubeka. Iindlela zinokuyilwa ngokujonga ubunzima beelori ezivuselelayo. I-RMC ingahanjiswa ngamaloli amancinci athwala umthamo wee-cubic metres ukuya kwezisixhenxe zekhonkrithi. Ukujonga izibonelelo ze-RMC ngaphezulu kokudityaniswa kwesiza, i-RMC ithandwa kwihlabathi liphela. Inokuqatshelwa into yokuba phantse isiqingatha sevolumu yekhonkrithi esetyenzisiweyo kwihlabathi liphela iveliswa kwizityalo zeRMC.
Izithako ze-RMC yisamente, umqukumbelo oxineneyo, umlinganiso ocoliweyo, amanzi kunye nokudityaniswa kwemichiza. Phantsi kwemigangatho yethu yesamente, kuchazwe iindidi ezingama-27 zesamente. Uhlobo lwe-CEM I sisamente esekwe ngokuqinileyo. Kwezinye iintlobo, inxenye ye-clinker ithathelwa indawo ngumxube wezimbiwa, ofana ne-fly ash, i-slag, njl.njl. Ngenxa yesantya esicothayo sokuphendula ngamachiza ngamanzi, isamente esekwe kwizimbiwa ibhetele xa ithelekiswa nesamente ye-clinker. Ukulibaziseka kwesamente okumbiwa kwisimbiwa kunye nokugcina ikhonkrithi isebenza ixesha elide. Iyanciphisa ukuqokelelana kobushushu kwikhonkrithi ngenxa yokuphendula kancinci ngamanzi.
