Tsarin Calciumfoda ne fari ko rawaya dan kadan, wanda zai iya hanzarta saurin hydration na siminti tare da guje wa matsalar saurin saita saurin sanyi a lokacin hunturu ko ƙarancin zafin jiki da yanayin rigar, don haɓaka ƙarfin farkon turmi. A yau zan ba ku labarintsarin calcium don hanzarta saiti da hardening na kankare menene takamaiman?
Tsarin Calcium yana hanzarta saiti da taurin kankare ta:
1. Rage lokacin saitin farko
2. Daidaita jinkirin saitin siminti a ƙarƙashin ƙananan yanayin zafi
3. Ƙara girman girma na ƙarfin farko
4. Rage lokacin rufewa a cikin ƙirar a cikin samar da sassan da aka riga aka tsara
5. Rage lokacin siminti don isa ga ƙarfin lodinsa
Misali, ana amfani da simintin Portland gabaɗaya a cikin busasshiyar turmi, wanda ke da ƙarancin ƙarfi a farkon matakin da ƙarfi mai ƙarfi a mataki na gaba, kuma ƙara adadin da ya dace na tsarin calcium yana da amfani don haɓaka ƙarfin farkon samfurin.
A cikin tsarin siminti na Portland.tsarin calcium yana da tasiri na inganta coagulation da ƙarfin farko, saboda ions masu tasowa a cikin HCOO- na iya haifar da kamancen AHt da AFm (C).₃A·3 Ca (HCOO)₂30H₂OC₃A·Ca (HCOO)·10H₂0, da dai sauransu), wanda ke rage lokacin saita siminti sosai.
Bugu da kari,tsarin calciumna iya inganta hydration na calcium silicate, saboda HCOO-ions suna yaduwa da sauri fiye da Ca2+ ions, kuma suna iya shiga cikin hydration Layer na C3S da C2S, yana haɓaka hazo na Ca (OH)₂da bazuwar silicate na calcium. HCOO-ions kuma na iya ƙara ɗaure ƙwayoyin siliki don amsawa tare da OH- ta hanyar aikin sinadarai, ta yadda za a haɗa ƙungiyoyin silicate na kusa, haɓaka samuwar CSH gel, da haɓaka ƙarfin turmi siminti.
