Nano bismuth oxide modified functional cement-based material and preparation method thereof
The invention discloses a nano bismuth oxide modified functional cement-based material and a preparation method thereof, and belongs to the technical field of concrete.The nano bismuth oxide modified functional cement-based material is composed of cement, nano bismuth oxide and water, the nano bismuth oxide modified functional cement-based material is prepared from, by mass, 98%-99.5% of cement and 0.5%-2% of nano bismuth oxide, and the water-binder ratio of raw materials of a nano bismuth oxide composite cement binding material is 0.4. The preparation method comprises the following steps: (1) dispersing nano bismuth oxide into an aqueous solution to obtain nano bismuth oxide dispersion liquid; and (2) cement and an aqueous solution are stirred to obtain cement slurry, then the cement slurry and the nano bismuth oxide dispersion liquid are mixed and stirred, and the nano bismuth oxide composite cement-based cementing material is obtained, so that the mechanical property and durability of the cement-based material are improved, and the cement-based material is endowed with a purification effect.
本发明公开了一种纳米氧化铋改性功能水泥基材料及其制备方法，属于混凝土技术领域，由水泥、纳米氧化铋与水组成，按照质量百分比，水泥占98％～99.5％，纳米氧化铋占0.5％～2％，纳米氧化铋复合水泥胶凝材料的原料水胶比为0.4。制备方法，包括如下步骤：(1)将纳米氧化铋分散到水溶液中，得到纳米氧化铋分散液；(2)将水泥与水溶液进行搅拌得到水泥浆料，然后将水泥浆料和纳米氧化铋分散液混合搅拌，得到纳米氧化铋复合水泥基胶凝材料，从而提高水泥基材料的力学性能、耐久性能，并赋予其净化功效。
