Ni ubuhe buryo bwa sima? Kandi ni ubuhe bwoko?

Ibikoresho bya sima nibintu bikoreshwa muguhuza cyangwa gufunga ibindi bikoresho hamwe kugirango bibe misa ikomeye. Mu bwubatsi, ikoreshwa muguhuza inyubako no gukora inyubako. Hariho ubwoko bwinshi bwibikoresho bya sima biboneka kugirango bikoreshwe mubwubatsi, harimo:

1. Portland Cement: Ubu ni ubwoko bwa sima bukoreshwa mubwubatsi. Ikozwe no gushyushya amabuye n'ibumba mu itanura kugirango ikore clinker, hanyuma igahinduka ifu nziza. Isima ya Portland ikoreshwa muburyo butandukanye bwo gusaba, harimo kubaka urufatiro, inkuta, hasi.
2. Hydraulic Cement: Ubu bwoko bwa sima burakomera iyo buhuye namazi. Irakoreshwa mubisabwa aho hakenewe sima ikomeye, yihuta-gushiraho sima, nko mukubaka ingomero, ibiraro, na tunel.
3. Lime: Lime ni ubwoko bwibikoresho bya sima byakoreshejwe mumyaka ibihumbi. Ikozwe no gushyushya hekeste kubushyuhe bwo hejuru kugirango itange igihe cyihuse, hanyuma ikavangwa namazi kugirango ikore lime hydrated. Tungurusumu ikoreshwa mubisabwa aho hakenewe sima ihumeka, yoroheje, nko kubaka inyubako namateka.
4. Gypsumu: Gypsumu ni ubwoko bwibikoresho bya sima bikozwe no gushyushya urutare rwa gypsumu ubushyuhe bwinshi hanyuma ukabisya mu ifu nziza. Ikoreshwa mubisabwa aho hakenewe sima yoroheje, irwanya umuriro, nko mukubaka inkuta zimbere nigisenge.
5. Isima ya Pozzolanic: Ubu bwoko bwa sima bukozwe no kuvanga ibikoresho bya pozzolanic (nk'ivu ry'ibirunga) hamwe na sima ya Portland. Isima ya Pozzolanic ikoreshwa mubisabwa aho hakenewe sima ifite igihe kirekire kandi ikarwanya ibitero byimiti.
