Kaalshiyam Formate (Ca(HCOO)₂) ee Fuuq-celinta Sibidhka: Saamaynta iyo Hababka

Kaalshiyam qaabaysan (Ca(HCOO)₂), oo ah wax soo saar ka soo baxa wax soo saarka polyol, ayaa si weyn loogu isticmaalaa sibidhka sida dardar-geliye degdeg ah, saliideeye, iyo kor u qaadis xoog hore, taasoo si weyn u soo gaabinaysa wakhtiga adkaanta iyo dardargelinta dejinta.

Sibidhka caadiga ah ee Portland, Ca(HCOO)₂ wuxuu kor u qaadaa fuuq-baxa C3S (tricalcium silicate) wuxuuna kordhiyaa sameynta ettringite (AFt), taasoo kor u qaadaysa xoogga hore. Si kastaba ha ahaatee, saameynta ay ku leedahay fuuq-baxa sibidhka sulphoaluminate (SAC) wali lama sahamin.

Daraasaddan, waxaan ku baarnay saameynta Ca(HCOO)₂ ay ku leedahay fuuq-baxa hore ee SAC annagoo falanqeynayna:

• Dejinta waqtiga
• Kulaylka fuuq-baxa
• XRD (kala-soocidda raajada)
• TG-DSC (kalorimetry-ka sawir-qaadista thermogravimetric-differential)
• SEM (iskaan-gareynta mikroskoobka elektarooniga ah)

Natiijooyinka waxay bixiyaan aragtiyo ku saabsan habka uu Ca(HCOO)₂ ugu shaqeeyo fuuq-celinta SAC, taasoo gacan ka geysaneysa faham qoto dheer oo ku saabsan waxqabadkiisa nidaamyada kale ee sibidhka.
