Cement-based material as well as preparation method and application thereof
The invention relates to a cement-based material as well as a preparation method and application thereof. The concrete comprises the following raw material components in parts by weight: 90-100 parts of cement, 12-18 parts of fly ash, 60-65 parts of fine sand, 1-3 parts of silica fume, 0.5-2 parts of an expanding agent, 0.3-0.6 part of a water reducing agent and 25-30 parts of water, the fine sand is quartz sand of which the particle size is less than or equal to 0.6 mm and the fineness is 1.4-1.6. According to the cement-based material, the quartz sand with specific particle size and fineness is adopted as the fine sand to be matched with the other components according to a reasonable proportion, the prepared cement-based material has ultrahigh fluidity while the material strength is guaranteed, and the grouting requirement and the mechanical property requirement during preparation of the artificial coarse aggregate can be met. Besides, by reasonably adjusting the proportion of the components of the raw materials, the mixing gradation of the cement-based material is optimized, the manufacturing cost is reduced while the performance requirements of the material are met, and the cement-based material has good application prospects.
本发明涉及一种水泥基材料及其制备方法和应用。按重量份计，包括如下原料组分：水泥90～100份、粉煤灰12～18份、细砂60～65份、硅灰1～3份、膨胀剂0.5～2份、减水剂0.3～0.6份以及水25～30份；所述细砂为粒径≤0.6mm、细度为1.4～1.6的石英砂。本发明通过采用特定粒径与细度的石英砂作为细砂与其余各组分按照合理配比进行配合，制备的水泥基材料在保证材料强度的同时具有超高流动性，能够满足制备人造粗集料时的注浆需求和力学性能需求。此外，通过对原料各组分的配比进行合理调整，使得水泥基材料的混合级配得以优化，在满足材料性能要求的同时降低了制造成本，具有良好的应用前景。
