Kodi kuchuluka kwa calcium formate mu simenti ndi kotani?

M'chilimwe, mlingo wa Kalisiyamu Formate nthawi zambiri imakhala 0.3% ~ 0.7% ya kulemera kwa simenti.
M'nyengo yozizira, mlingo uyenera kuwonjezeka pamene kutentha kumatsika, nthawi zambiri 0.5% ~ 1%, ndi malire apamwamba a 2.5%.
Pa simenti (yomwe nthawi zambiri imakhala ndi mphamvu yoyambirira koma mphamvu yocheperako) yomwe imagwiritsidwa ntchito mu matope ouma, kuwonjezera calcium formate yokwanira ku chinthucho ndikothandiza pakukweza mphamvu yoyambirira. Calcium formate yathu imakhala ndi madzi abwino, imasungunuka kwambiri, ndipo imakhala ndi ntchito yolowetsa mpweya (kusunga madzi ndi 1.5% ndikuchepetsa kuchuluka kwa madzi ndi 5%). Ikhoza kuwonjezera kugwira ntchito kwa matope ndikuwonjezera kulimba.

Calcium formate konkire accelerator imapereka mphamvu mwachangu, chloride yochepa komanso kugwira ntchito bwino kwambiri—kwabwino kwambiri popititsa patsogolo ntchito yomanga. Dinani kuti muwone mapulani athu operekera zinthu tsopano!
