ABSTRACT A method of making a building material by activation of latently hydraulic finely ground granulated basic blast-furnace slag to form a direct acting hydraulic binder is disclosed. The slag is mixed with water, sand and ballast material as well as with a combination of acidic and basic components. The acidic components consist of phosphates, optionally in combination with strongly acting sulfates, and the basic components consist of oxides or other compounds of earth metals, optionally in combination with zinc. Thereby, a concrete having great mechanical strength and high chemical resistance is obtained.
