I-Calcium Formate (Ca(HCOO)₂) kwi-Cement Hydration: Iziphumo kunye neendlela

I-Calcium formate (Ca(HCOO)₂), imveliso ephuma kwimveliso ye-polyol, isetyenziswa kakhulu kwisamente njengesikhawulezisi sokumisela ngokukhawuleza, isithambisi, kunye nesiphuculi samandla okuqala, nto leyo enciphisa kakhulu ixesha lokuqina kunye nokumisela ngokukhawuleza.

Kwisamente eqhelekileyo yasePortland, iCa(HCOO)₂ ikhuthaza ukufuma kweC3S (triccalcium silicate) kwaye yonyusa ukwakheka kwe-ettringite (AFt), ngaloo ndlela yonyusa amandla okuqala. Nangona kunjalo, impembelelo yayo ekufuma kwesamente ye-sulphoaluminate (SAC) ayikafunyanwa.

Kolu phononongo, siphande ngempembelelo yeCa(HCOO)₂ ekufakweni kwamanzi kwangoko kweSAC ngokuhlalutya:

• Ixesha lokuseta
• Ubushushu bokufuma kwamanzi
• I-XRD (i-X-ray diffraction)
• I-TG-DSC (i-calorimetry yokuskena ye-thermogravimetric-differential)
• I-SEM (ukuskena imakroskopu ye-electron)

Ezi ziphumo zibonelela ngengqiqo kwindlela esebenza ngayo i-Ca(HCOO)₂ kwi-SAC hydration, nto leyo enegalelo ekuqondeni okunzulu ukusebenza kwayo kwiinkqubo zesamente ezizezinye.
