Calcareous sand reinforced cement-based material and preparation method thereof
The invention relates to the technical field of reinforced cement, in particular to a calcareous sand reinforced cement-based material and a preparation method thereof, and the calcareous sand reinforced cement-based material comprises the following raw materials: Portland cement, fly ash, an expanding agent, calcareous sand, water and a water reducing agent. The calcareous sand is used for replacing quartz sand commonly used in the prior art, the calcareous sand has many inner holes, when the inner holes are filled with a cementing material, the performance of an interface transition layer can be effectively improved, and the strength of the calcareous sand cement-based material is enhanced. During marine environment construction, calcareous sand is used for replacing quartz sand, local materials are used, the cost for manufacturing the cement-based material can be greatly reduced, and wide application of the cement-based material is better promoted.
本发明涉及增强水泥技术领域，具体涉及一种钙质砂增强水泥基材料及其制备方法，所述钙质砂增强水泥基材料原料包括以下组分：硅酸盐水泥、粉煤灰、膨胀剂、钙质砂、水、减水剂。本发明使用钙质砂代替现有技术中常用的石英砂，钙质砂有很多内孔隙，当胶凝材料填充内孔隙时，可以有效提高和改善界面过渡层的性能，增强钙质砂水泥基材料的强度。海洋环境施工时，用钙质砂来替代石英砂，就地取材，可以大大降低制作水泥基材料成本，更高地促进水泥基材料的广泛使用。
