ALKALI-ACTIVATED BINDER WITH NO CEMENT INCLUDING COMPLEX ALKALI-ACTIVATED AGENTS AND MORTAR OR CONCRETE COMPOSITION USING THE SAME

摘要

PURPOSE: A cement-free alkali-activated binder including composite alkali activator is provided to improve compressive strength of mortar and/or concrete, quick setting property and fluidity by controlling the content and combination ratio of alkali activators. CONSTITUTION: A cement-free alkali-activated binder includes: 88-96 weight% of one or more raw materials selected from the group consisting of slag, fly ash, and metakaolin; and 4-12 weight% of composite alkali activators containing alkaline hydroxide and carbonate. The composite alkali activator includes alkaline hydroxide and carbonate in a weight ratio of 2-4:4-6. The alkaline hydroxide is one or more selected from the group consisting of potassium hydroxide, sodium hydroxide, calcium hydroxide, magnesium hydroxide and barium hydroxide.
