The advantages of high alumina cement (early strength, resistance to sulphate attack) are preserved and its disadvantage (weakens with age) is solved by mixing it 50:50 with ground granulated blast furnace slag. This encourages formation of gehlenite octahydrate in preference to or to the exclusion of the harmful 'conversion' (weakening) reaction.
