Calcium formate ji nɔ ko ni akɛfataa he ni bɛ hewalɛ ko ni fiteɔ dade ni akɛwoɔ mli lɛ nɔ. E molecular fɔmula ji C2H2CaO4. Ehaa tricalcium silicate ni yɔɔ simenti mli lɛ mli nu lɛ yaa oya titri, ni no haa simenti ŋmɔtɔ lɛ mli hewalɛ yaa hiɛ mra. Nɔ ni calcium formate lɛ tsuɔ yɛ sũ mli hewalɛ nɔ lɛ damɔ tricalcium silicate ni yɔɔ simenti lɛ mli lɛ nɔ titri: kɛji akɛ tricalcium silicate ni yɔɔ sũ lɛ mli lɛ faaa lɛ, ebaahaŋ sũ lɛ mli hewalɛ ni sɛɛ tsɛɔ lɛ aba shi, ni eyɛ antifreeze hewalɛ ko hu yɛ hulutsoo be ni baa shi lɛ mli.

Ani otaoɔ nɔ ko ni fiteee, ni hulutsoo be lɛ baa shi mra hewalɛwoo? Calcium formate lɛ haa sũ mli sũ lɛ mli hewalɛ yaa hiɛ mra (ni hewalɛ ni sɛɛ tsɛɔ lɛ sɛɛ efooo!)—ehi jogbaŋŋ kɛha tsumaa be ni mli wa. Tsɔɔmɔ wɔ sane koni wɔkase bɔ ni ewoɔ onitsumɔi lɛ anɔ!
