Hydraulic lime is a product of moderate calcination (not before sintering) of marly limestones containing from 6 to 20% clay impurities. Hydraulic lime tends to harden not only in air but also in water . As a result of firing, not only CaO free lime is formed, but also its chemical compounds with clay oxides - silicates, aluminates and calcium ferrites, which can harden not only in air but also in water.
Applied in the form of slaked lime (powder) and ground quicklime. Hydraulic lime is used as raw material for the preparation of mortars, concretes with low strength. Unlike solutions prepared using air lime , such solutions can be used for parts of buildings that are in wet conditions during operation.
