Calcium Formate (Ca(HCOO)2) eka Cement Hydration: Vuyelo na Maendlelo

Calcium formate (Ca(HCOO)2), byproduct ya vuhumelerisi bya polyol, yitirhisiwa ngopfu eka semende tani hi rapid-setting accelerator, lubricant, na early-strength enhancer, leswi hungutaka swinene nkarhi wo nonoka xikan’we naku hatlisisa setting.

Eka semende ya Portland leyi tolovelekeke, Ca(HCOO)2 yi hlohletela hydration ya C3S (tricalcium silicate) naswona yi engetela ku endliwa ka ettringite (AFt), xisweswo yi tlakusa matimba yosungula. Hambiswiritano, nkucetelo wa yona eka hydration ya sulphoaluminate cement (SAC) a wu se lavisisiwa.

Eka dyondzo leyi, hi lavisisile mbuyelo wa Ca(HCOO)2 eka hydration yosungula ya SAC hiku xopaxopa:

• Ku veka nkarhi
• Ku hisa ka mati
• XRD (ku hambanisiwa ka X-rheyi) .
• TG-DSC (thermogravimetric-ku hambana ka ku kambela kalorimetry) .
• SEM (ku tirhisa microscopy ya elektroni leyi skena) .

Swikumiwa swi nyika vutivi eka endlelo ra ntirho wa Ca(HCOO)2 eka SAC hydration, leswi hoxaka xandla eka ku twisisa loku dzikeke ka matirhelo ya yona eka tisisiteme tin’wana ta semende.
