Abstract

A hardener for hydraulic mortars and cements It comprises an aluminium sulphate optionally in admixture with a potassium base, urea, an acetate, a formate, aluminate, a carbonate, a ligno sulphate, a permanganate, a stearate or their derivatives dissolved in oils or other products. They are used as adjuvants for the setting and hardening mortar and cement.
