Modified regenerated micro powder and preparation method thereof
The invention relates to modified regenerated micro powder and a preparation method thereof. The invention discloses a recycled cement mortar, which is prepared from the following raw materials: recycled cement mortar particles, nano calcium silicate, carbon nanotubes and an exciting agent, the mass ratio of the nano calcium silicate to the cement mortar particles is 2%-5%, and the mass ratio of the carbon nanotubes to the cement mortar particles is 2%-5%. The doping amount of the exciting agent is calculated according to the alkali equivalent, and the proportion is 3%-8% of the mass of the regenerated micro-powder particles. The concrete regenerated admixture can be obtained by performing physical grinding and chemical excitation activation on the nano calcium silicate, the carbon nanotubes and the regenerated micro powder. According to the invention, waste concrete resources are utilized, the problem of serious lack of admixtures such as fly ash and mineral powder is solved, the use amount of cement is reduced, low-carbon preparation of building materials is realized, and the economic and social benefits are remarkable.
本发明涉及一种改性再生微粉及其制备方法。该包括如下原料：再生水泥砂浆颗粒、纳米硅酸钙、碳纳米管、激发剂，其中，纳米硅酸钙与水泥砂浆颗粒质量比例：2％～5％，碳纳米管与水泥砂浆颗粒质量比例：2％～5％；激发剂掺量以碱当量计算，比例为再生微粉颗粒质量的3％～8％。通过将纳米硅酸钙、碳纳米管与再生微粉经物理粉磨和化学激发活化后可以得到的混凝土再生掺合料。本发明利用废弃混凝土资源，解决粉煤灰、矿粉等掺合料严重缺乏的问题，减少水泥用量，有利于实现建筑材料低碳化制备，经济和社会效益显著。
