Calcium formate yog ib qho khoom siv ntxiv uas tsis muaj kev cuam tshuam rau kev txhim kho hlau. Nws cov mis molecular yog C₂H₂CaO₄. Nws feem ntau ua kom cov dej ntawm tricalcium silicate hauv cement sai dua, yog li ua kom lub zog thaum ntxov ntawm cov cement mortar zoo dua. Qhov cuam tshuam ntawm calcium formate rau lub zog ntawm cov mortar feem ntau nyob ntawm cov ntsiab lus ntawm tricalcium silicate hauv cov cement: yog tias cov ntsiab lus tricalcium silicate tsawg, nws yuav tsis txo qhov zog lig ntawm cov mortar, thiab nws kuj muaj qee yam antifreeze effect ntawm qhov kub qis.

Nrhiav ib yam khoom uas tsis muaj xeb, tsis kub dhau, thiab ua rau lub zog thaum ntxov zoo dua? Calcium formate ua rau lub zog thaum ntxov ntawm cov mortar zoo dua (tsis muaj kev poob zog thaum kawg!) - zoo meej rau lub sijhawm tsim kho sai. Sau ntawv rau peb kom paub seb nws ua rau koj cov haujlwm zoo dua li cas!
