Carbon dot and silicon dioxide co-doped modified cement-based material and preparation method thereof
The invention relates to the technical field of cement-based materials, in particular to a carbon dot and silicon dioxide co-doped modified cement-based material and a preparation method thereof.In the carbon dot and silicon dioxide co-doped modified cement-based material, 2-7% of silicon dioxide and 0.1-1% of carbon dots are added into every 100 g of Portland cement, 290 g of sand and 40 g of water, and after the carbon dots are added into the cement-based material, the content of the carbon dots in the cement-based material is 1-3%. The fluidity of the cement mortar can still be maintained after the dosage of silicon dioxide is obviously increased, so that the silicon dioxide can effectively improve the hydration performance and the mechanical property of a cement-based material.
本发明涉及水泥基材料技术领域，具体涉及一种碳点和二氧化硅共掺改性水泥基材料及其制备方法，碳点和二氧化硅共掺改性水泥基材料中，每100g硅酸盐水泥、290g砂子和40g水中，加入如下原料：二氧化硅2～7％，碳点0.1～1％，该水泥基材料在添加碳点后，能显著增加二氧化硅用量后仍保持水泥砂浆的流动性，使得二氧化硅能有效地提高水泥基材料水化性能和力学性能。
