Kalisiyumu ikorani ifu yera cyangwa yumuhondo yoroheje, ishobora kwihutisha umuvuduko wa hydrata ya sima kandi ikirinda ikibazo cyumuvuduko ukabije wogushiraho mugihe cyitumba cyangwa ubushyuhe buke nubushyuhe butose, kugirango uzamure imbaraga za kare za minisiteri. Uyu munsi ndakubwira ibyaweKalisiyumu kwihutisha gushiraho no gukomera bya beto niki cyihariye?
Kalisiyumu ikora byihutisha gushiraho no gukomera bya beto na:
1. Gabanya igihe cyambere cyo gushiraho
2. Kora igenamigambi rya sima gahoro gahoro
3. Ongera umuvuduko witerambere ryimbaraga hakiri kare
4. Gabanya igihe cyo gusoza muri module mugukora ibice byakozwe mbere
5. Gabanya igihe cya beto kugirango igere kubushobozi bwayo
Kurugero, sima ya Portland ikoreshwa muri minisiteri yumye, irangwa nimbaraga nke mubyiciro byambere nimbaraga nyinshi mugice cyanyuma, kandi kongeramo urugero rukwiye rwa calcium ikora ni byiza kuzamura imbaraga zambere yibicuruzwa.
Muri sisitemu ya sima ya Portland,Kalisiyumu ifite ingaruka zo guteza imbere coagulation n'imbaraga hakiri kare, kuko ion zikora muri HCOO- zishobora gukora ibintu bisa na AHt na AFm (C₃A·3Ca (HCOO)₂ ·30H₂OC₃A·Ca (HCOO)·10H₂0, nibindi), bigabanya cyane igihe cyo gushiraho sima.
Byongeye,KalisiyumuIrashobora guteza imbere hydratiya ya calcium silikatike, kubera ko HCOO- ikwirakwizwa vuba kurusha Ca2 + ion, kandi irashobora kwinjira mumashanyarazi ya C3S na C2S, byihutisha imvura ya Ca (OH)₂no kubora kwa calcium silikate. HCOO- ion irashobora kandi guhuza atomike ya silicon kugirango yifatanye na OH- binyuze mubikorwa bya shimi, kugirango ihuze amatsinda ya silikatike yegeranye, iteza imbere ishingwa rya gel CSH, kandi itezimbere imbaraga zikomeye za sima.
