<p>In a method for the production of high-strength, acid-resistant concrete by use of water, hydraulic binder and aggregates, a hydraulic binder containing aluminosilicates, calciumsulfate and an activator containing salts of alkalimetals is applied wherein the aluminosilicates are chosen from the group consisting of furnace slag, clay, marl and industry-by-products like flue-ash with the requirement that the Al<SUB>2</SUB>O<SUB>3</SUB>-content of the binder is greater than 5% (w/w) and that furnace slag is present in an amount less than 35% (w/w) of the binder and that cement kiln dust in amounts from 1 to 20% (w/w) of the binder is applied as activator whereby the hydraulic activator is applied in amounts >400 kg per m<SUP>3 </SUP>concrete safeguarding a water/binder ratio from 0.25 to 0.40.</p> |
