I-calcium formate yi-additive engenawo umphumela wokubola ekuqiniseni insimbi. Ifomula yayo yamamolekhyuli yi-C₂H₂CaO₄. Irhabisa khulu ukuthambisa kwe-tricalcium silicate kusimende, ngaleyo ndlela ikhuphule amandla wokuthoma wesimende. Umthelela we-calcium formate ekuqineni kwedaka uthembele khulu ekuqukethwe kwe-tricalcium silicate kusimende: nangabe okuqukethwe kwe-tricalcium silicate kuphasi, angeze kwehlisa amandla we-mortar, begodu inomphumela othileko wokulwisana nokuqanda emazingeni womtjhiso aphasi.

Ufuna isikhuthazi samandla sokuthoma esinganakugqwala, esivumela amazinga womtjhiso aphasi? I-calcium formate iqinisa amandla wodaka ekuthomeni (ngaphandle kokulahlekelwa kwamandla ngemva kwesikhathi!)—ilungele isikhathi sokwakha esiqinileko. Sithumelele umlayezo ukufunda bona iphakamisa njani amaphrojekthi wakho!
