Kalisiyumu yaulere, silicon oxide ndi zinthu zina zomwe zili mu konkriti pambuyo pa zochitika zovuta za mankhwala, zomwe zimapangitsa kuti zinthu zikhale zolimba, mankhwala awa pamapeto pake amapangitsa kuti pamwamba pa konkriti pakhale kukhuthala, motero kumawonjezera mphamvu, kuuma, ndi kukana kwa pamwamba pa konkriti.
