Abstract
A blended, hydraulic cement binder, is disclosed, consisting of water, fly ash, Type III portland cement, Type I portland cement, slag cement, ground silica, boric acid, borax, citric acid and an alkali metal activator. The cement binder and sequences for mixing the composition, is particularly useful because it provides: time to mix all components adequately, unrestricted transporting time that can be terminated, at will, followed by alterable placement and finishing times. The cement binder can be used as a neat cement or it can be extended with fillers, such as sand and gravel, to make mortar or concrete, that rapidly gains very high structural strengths.
