Calcium Hydroxide - an overview | ScienceDirect Topics

The addition of a sufficient quantity of calcium to geopolymers in the form of calcium hydroxide can lead to the formation of phase-separated C-(A)-S-H and geopolymer (N-A-S-H) gels. This is known to be more prevalent at relatively low alkalinity - low NaOH concentrations in hydroxide-activated systems ( Alonso and Palomo 2001 ), or higher SiO 2 /Na 2 O ratios in silie-activated systems ( Yong 2009 ).

zinc | Properties, Uses, & Facts | Britannica

Zinc itself forms an impervious coating of its oxide on exposure to the atmosphere, and hence the metal is more resistant to ordinary atmospheres than iron and corrodes at a much lower rate. In addition, because zinc tends to oxidize in preference to iron, some protection is afforded the steel surface even if some of it is exposed through cracks.
