The invention provides a concrete nano reinforcing agent as well as a preparation method and application thereof. The concrete nano reinforcing agent is prepared from the following raw materials: silicon dioxide, graphene and calcium silicate, the particle size of the silicon dioxide is 1-20 nm; the particle size of the graphene is 20 to 200 nm; the particle size of the calcium silicate is 200 to 700 nm. According to the concrete nano-reinforcing agent, the three nano-materials with different particle sizes are adopted, the compactness of concrete can be remarkably improved through the synergistic effect of the three nano-materials, gaps of the concrete are filled with the nano-materials with the particle sizes distributed in a stepped mode, the compactness of the concrete is improved, and then the strength and durability of the concrete are improved.
本发明提供了一种混凝土纳米增强剂及其制备方法和应用，所述混凝土纳米增强剂的原料包括：二氧化硅、石墨烯和硅酸钙；所述二氧化硅的粒径为1‑20nm；所述石墨烯的粒径为20‑200nm；所述硅酸钙的粒径为200‑700nm。本发明所述混凝土纳米增强剂采用三种不同粒径的纳米材料，利用三者之间的协同作用可以显著增加混凝土的密实度，混凝土的空隙被粒径阶梯分布的纳米材料进行填充，使得混凝土的密实度增加，进而提高混凝土的强度和耐久性。
