Sima ya sima

Sima ya Sulphoaluminate (SAC) ni ubwoko bwa sima igenda ikundwa cyane kubera imiterere yihariye nibyiza kuruta ubundi bwoko bwa sima. SAC ni sima ya hydraulic ikorwa muguhuza sulphoaluminate clinker, gypsum, hamwe na calcium sulfate nkeya. Muri iyi ngingo, tuzasesengura inkomoko, ibiranga, ibyiza, hamwe nikoreshwa rya sima sulphoaluminate.

Inkomoko ya sima ya Sulphoaluminate yatunganijwe bwa mbere mu Bushinwa mu myaka ya za 70. Byabanje gukoreshwa mubikorwa bidasanzwe, nka byihuse-gushiraho beto no gusana minisiteri. Mu myaka yashize, SAC imaze kwamamara nkuburyo burambye bwa sima gakondo ya Portland.

Ibiranga Sulphoaluminate sima ifite ibintu byinshi bidasanzwe bituma itandukana nubundi bwoko bwa sima. Muri ibyo biranga harimo:

1. Igenamiterere ryihuse: SAC ishyiraho vuba, hamwe nigihe cyo gushiraho iminota 15-20. Ibi bituma biba byiza mubisabwa aho bisabwa byihuse, nko mubihe bikonje cyangwa mugihe bikenewe byihuse.
2. Imbaraga zo hambere kare: SAC ifite imbaraga zo hambere kare, hamwe nimbaraga zo kwikuramo hafi MPa 30-40 nyuma yumunsi umwe wo gukira. Ibi bituma biba byiza mubisabwa aho hakenewe imbaraga hakiri kare, nko muri beto ya preast cyangwa gusana.
3. Ikirenge gito cya karuboni: SAC ifite ikirenge cyo hasi cya karubone kurusha sima ya Portland gakondo, kuko isaba ubushyuhe buke mugihe cyo gukora kandi irimo clinker nkeya.
4. Kurwanya sulfate nyinshi: SAC ifite imbaraga nyinshi zo kurwanya sulfate, ituma ikwiriye gukoreshwa mubidukikije bifite sulfate nyinshi, nko ku nkombe.

Ibyiza Sulphoaluminate sima itanga inyungu nyinshi kurenza ubundi bwoko bwa sima, harimo:

1. Kugabanya ikirenge cya karuboni: SAC ifite ikirenge cyo hasi cya karubone ugereranije na sima gakondo ya Portland, ibyo bikaba aribwo buryo burambye bwo kubaka.
2. Igenamiterere ryihuse: SAC ishyiraho vuba, ishobora guta igihe no kugabanya ibiciro byubwubatsi.
3. Imbaraga nyinshi kare: SAC ifite imbaraga zo hambere, zishobora kugabanya igihe gikenewe cyo gukira no kongera umusaruro.
4. Kurwanya sulfate nyinshi: SAC ifite imbaraga nyinshi zo kurwanya sulfate, ishobora kongera igihe kirekire cyubatswe mubidukikije.

Koresha sima ya Sulphoaluminate ikoreshwa muburyo butandukanye, harimo:

1. Gushiraho byihuse: SAC ikoreshwa mubisabwa aho bisabwa byihuse, nko mubihe bikonje cyangwa mugusana byihuse.
2. Precast beto: SAC ikoreshwa kenshi mugukora ibicuruzwa byabugenewe, nk'imiyoboro ya beto, ibisate, hamwe na paneli.
3. Gusana minisiteri: SAC ikoreshwa kenshi nka minisiteri yo gusana ibyubaka, kuko ishyiraho vuba kandi ifite imbaraga zo hambere.
4. Kwishyiriraho-beto: SAC irashobora gukoreshwa mugukora beto-y-urwego-rwiza, nibyiza kubisabwa aho bisabwa neza, urwego rusanzwe.

Umwanzuro Sulphoaluminate sima nubwoko budasanzwe bwa sima itanga ibyiza byinshi kurenza sima gakondo ya Portland. Ifite ikirenge cyo hasi cya karubone, ishyiraho vuba, ifite imbaraga nyinshi kare, kandi irwanya cyane igitero cya sulfate. SAC ikoreshwa mubikorwa bitandukanye, harimo gushiraho byihuse, beto ya preast, gusana minisiteri, hamwe na beto yo kwishyiriraho. Nkuko kuramba bibaye ngombwa kwitabwaho mubwubatsi, ikoreshwa rya SAC rishobora kwiyongera mubyamamare.
