Calcium formate ubedo piny ma ju medo ma epe ku adwogi marac ikum steel reinforcement. Formula pa molecule pare ubedo C₂H₂CaO₄. Etimo rwom ma malu pa tricalcium silicate i cement, man eketho cement mortar doko tek. Adwogi pa calcium formate ikum tego pa mortar ucungo iwi kadhiri pa tricalcium silicate i cement: ka tricalcium silicate utiye nok, ebi dwoko piny tego pa mortar, man de etiye ku tic moko ma nyayu lyethu i lyethu ma piny.

Ibeyenyo piny ma nyayu tego ma rwinyo ngo, man ma rwinyo ngo? Calcium formate medo tego pa mortar con (ma epe ku rweny pa tego!)—ber pi kare mi gedo ma nok. Cwal iwa waraga mi ngeyo kite ma ekonyo ko tic peri!
