Alkali-activated self-compacting concrete and preparation method thereof
The invention relates to alkali-activated self-compacting concrete and a preparation method thereof, and relates to the technical field of building materials. The alkali-activated self-compacting concrete comprises the following preparation raw materials in parts by weight: 10-15 parts of sulfate, no more than 3 parts of phosphate and/or carbonate, 5-15 parts of quick lime, 8-20 parts of an excitation material, 30-70 parts of an aggregate, 1-3 parts of an additive, and water. Cheap quick lime, sulfate, phosphate and/or carbonate are/is adopted as an alkali activator, so that the cost of the alkali-activated cementing material is greatly reduced, and the self-compacting concrete is good in construction performance, good in fluidity, long in setting time and high in early strength.
发明涉及一种碱激发自密实混凝土及其制备方法。涉及建筑材料技术领域。以重量份计，所述碱激发自密实混凝土的制备原料包括：硫酸盐10‑15份；磷酸盐和/或碳酸盐不超过3份；生石灰5‑15份；激发材料8‑20份；骨料30‑70份；外加剂1‑3份；水。采用廉价的生石灰、硫酸盐、磷酸盐和/或碳酸盐作为碱激发剂，极大地降低了碱激发胶凝材料的成本，且自密实混凝土施工性能好，流动性好，凝结时间长，早期强度高。
