Concrete based on granite stone powder and preparation method thereof
The invention discloses concrete based on granite stone powder and a preparation method thereof, and relates to the technical field of concrete preparation, the granite stone powder is changed from hydrophilic to hydrophobic through a chemical modification mode, the problems that the granite stone powder is large in water absorption capacity, adsorbs additives and the like are solved, the workability of a concrete mixture is improved, and smooth construction is guaranteed. By means of physical and mechanical grinding and grinding aid adding, the grindability and the specific surface area of granite powder are improved, agglomeration is reduced, the activity of the granite powder as a mineral admixture is improved, the micro-grading of concrete aggregate is improved through different stone powder particle sizes, and the compactness, the mechanical property and the durability of concrete are improved.
本发明公开了一种基于花岗岩石粉的混凝土及其制备方法，涉及混凝土制备技术领域，本发明通过化学改性的方式，将花岗岩石粉由亲水改为疏水，解决花岗岩石粉吸水量大、吸附外加剂等问题，改善混凝土拌合物和易性，保证施工顺利进行。通过物理机械粉磨、添加助磨剂的方式，提高花岗岩石粉的易磨性、比表面积，减少团聚，提升其作为矿物掺合料的活性，通过不同石粉粒径改善混凝土骨料的微级配，提升混凝土密实性、力学性能和耐久性。
