High-performance alkali-activated cementing material and preparation method thereof
The invention discloses a high-performance alkali-activated cementing material and a preparation method thereof. The high-performance alkali-activated cementing material comprises the following main components: siliceous iron tailing powder, fly ash, slag powder, silicon-calcium slag, water and an activator. The preparation method of the high-performance alkali-activated cementing material comprises the following steps: step 1, drying raw materials; 2, grinding the raw materials; step 3, proportioning the raw materials; and step 4, mixing and stirring. The alkali-activated cementing material is prepared by performing activity excitation on a slag fly ash system by using an alkali activator; the strength and heat resistance of the concrete can be improved through the characteristics of the activator sodium silicate, the generated product is attached and wrapped on the surface of the fly ash, so that the fly ash is separated from the outside, the setting time of the cementing material is prolonged, the quick setting performance of the alkali-activated cementing material is improved, and the activated slag cementing material has a good retarding effect, high compressive strength and low cost; the energy consumption is low.
本发明公开了一种高性能碱激发胶凝材料及其制备方法，它的主要成分是硅质铁尾矿粉、粉煤灰、矿渣粉、硅钙渣、水和激发剂；一种高性能碱激发胶凝材料的制备方法，包括步骤一，原料烘干；步骤二，原料研磨；步骤三，原料配比；步骤四，混合搅拌。本发明通过使用碱性激发剂对矿渣粉煤灰体系进行活性激发，制备碱激发胶凝材料；通过激发剂水玻璃的特性，可提升混凝土的强度和耐热性，并且生成的产物在粉煤灰表面附着包裹，使之与外界分割，延长胶凝材料的凝结时间，改善碱激发胶凝材料快凝的性能，激发矿渣胶凝材料具有良好的缓凝效果，抗压强度高，低成本，低能耗。
