Preparation method of ultra-high performance cement-based material doped with waste glass powder
The invention relates to the technical field of building material preparation, and discloses a preparation method of an ultra-high performance cement-based material doped with waste glass powder, and the preparation method comprises the following steps: S1, providing cement, waste glass powder, silica fume, fine aggregate, nano titanium dioxide, graphene, a phase change material, a green high-efficiency water reducing agent and steel fiber; s2, dispersing graphene in deionized water to form a graphene suspension; s3, carrying out microencapsulation treatment on the phase change material; s4, cement, waste glass powder, silica fume, fine aggregate and nano titanium dioxide are subjected to dry mixing, and a basic mixture is formed. The compactness and durability of the material are remarkably improved by adopting a magnetorheological fluid technology for compaction, microencapsulation of the phase change material and a carbon dioxide curing technology, and meanwhile, by adjusting the temperature and forming a carbonization layer, the freeze-thaw resistance and the permeation resistance are improved, and the service life is prolonged. In addition, environment-friendly materials and a high-efficiency water reducing agent are adopted, so that the preparation process is more energy-saving and environment-friendly.
