have an initial slump diameter of greater than 18 inches and/or a 1 hour slump diameter as measured according to ASTM C1611-14 and a final cure time of at least 60 minutes as measured using ASTM C191-13, as well as from 0% by volume to A water-free blend and self-consolidating geopolymer composition in the form of a slurry having an air content of 20% by volume. The composition comprises a mixture of water and cementitious reactive powder in a ratio of w/crp = 0.3-0.55, a cement hardening retarder, an alkali metal chemical activator selected from alkali metal salts and/or alkali metal bases and a freeze-thaw durable component (freeze-thaw resistant component). thaw durability component). The cementitious reactive powder comprises thermally activated aluminosilicate minerals and optionally inorganic minerals including alkaline earth metal oxides, aluminate cement, and calcium sulfate. Thermally activated aluminosilicate minerals are from the group consisting of fly ash, blast furnace slag, thermally activated clay, shale, metakaolin, zeolite, marl red mud, crushed rock, and crushed clay bricks. selected from at least one member of In addition, the method of making the self-consolidating geopolymer composition comprises water; mixing the cementitious reactive powder, cement hardening retarder, alkali metal chemical activator, and freeze-thaw durable component to prepare a slurry. |
