Calcium Hydroxide - an overview | ScienceDirect Topics

Its key feature is its high alkalinity (pH 11–12.5), and this can be achieved using calcium hydroxide powder mixed with pure water to the consistency of a light paste [34]. However, used in this way, calcium hydroxide does not set, has no mechanical strength and consequently there is the danger of it being displaced by the forces involved in placing a restorative material over it [ 35 ].
