Abstract
Disclosed are compositions containing at least 5 wt. % of a silicate based on the total weight of the composition, wherein the silicate is an alkali metal silicate and/or an alkaline earth metal silicate, at least 20 wt. % of one or more calcium oxygenates; and water to 100 wt. %.
Claims19
