Carbon dot modified cement-based material and preparation method thereof
The invention relates to a carbon dot modified cement-based material and a preparation method thereof, the carbon dot modified cement-based material comprises carbon dots, water, cement and sand, the carbon dots are prepared by an electrochemical method, and an electrolyte used by the electrochemical method is one of pure water, an aqueous solution containing 0.2%-0.5% of acetic acid and an aqueous solution containing 0.2%-0.5% of polypropylene. The electrolyte used in the invention comprises one of pure water, polyacrylic acid or acetic acid, the surface of the prepared carbon dot is rich in various functional groups, and when the cement-based material is prepared, the carbon dot is added, so that cement hydration can be promoted, hydration products can be uniformly distributed, the microstructure of the cement-based material is improved, and the compression resistance and compactness of the cement-based material are improved.
一种碳点改性水泥基材料及其制备方法，其中，碳点改性水泥基材料包括碳点、水、水泥和砂，其中，所述碳点由电化学法制备，电化学法所用电解液为纯水、含0.2％‑0.5％乙酸的水溶液、含0.2％‑0.5％聚丙烯的水溶液中的一种。本申请所用电解液包括纯水、聚丙烯酸或乙酸中的一种，所制得的碳点表面富含多种官能团，在制备水泥基材料时加入该碳点可以促进水泥水化，使水化产物分布均匀，改善水泥基材料的微观结构，提高水泥基材料的抗压能力和密实性。
