I-Calcium Formate (Ca(HCOO)2) ku-Cament Hydration: Imiphumela neendlela

I-Calcium formate (Ca(HCOO)₂), umkhiqizo wokukhiqiza i-polyol, isetjenziswa khulu kusimende njengesitjhukumisi sokuqinisa msinyana, isithambiso, kanye nesikhuthazi samandla sokuthoma, okwenza isikhathi sokuqinisa sibe sifitjhani khulu nokurhabisa ukujama.

E-Portland cement ejayelekileko, i-Ca(HCOO)2 ikhuthaza ukuthambisa kwe-C3S (tricalcium silicate) begodu ikhuphula ukwakheka kwe-ettringite (AFt), ngaleyindlela ikhulisa amandla wokuthoma. Kodwana, umthelela wayo ekuthambisani kwe-sulphoaluminate cement (SAC) awukahlolwa.

Kulesi sifundo, siphenye umthelela we-Ca(HCOO)2 ekuthomeni kokuthambisa kwe-SAC ngokuhlaziya:

• Ukubeka isikhathi
• Ukutjhisa kokuthambisa
• XRD (X-ray diffraction)
• I-TG-DSC (i-thermogravimetric-differential scanning calorimetry)
• I-SEM (i-elekthronikhi yokuskena)

Iindaba ezitholweko zinikela ngokuzwisisa ngendlela i-Ca(HCOO)2 esebenza ngayo ekuthambisani kwe-SAC, okufaka isandla ekuzwisiseni okujulileko kokusebenza kwayo kezinye iinhlelo zesimende.

Tlika lapha ukuthola isaphulelo se-calcium formate.

Ithuba lokonga iindleko lokuthenga i-Calcium formate!
