Anti-crack concrete and preparation method thereof
The invention provides anti-crack concrete, and belongs to the technical field of building materials. The building material comprises ordinary Portland cement, granite, artificial sand and a nanometer material. The nano material is at least one of nano silicon dioxide, nano calcium carbonate and nano titanium dioxide. According to the invention, the nano material is added, so that the obtained anti-crack concrete has the advantages of fast initial strength, high later strength, good impermeability and high bonding strength, and the early anti-crack performance of the concrete is effectively improved.
本发明提供了一种抗裂混凝土，属于建筑材料技术领域。本发明提供的包括普通硅酸盐水泥、米石、人工砂、纳米材料；所述纳米材料为纳米二氧化硅、纳米碳酸钙和纳米二氧化钛中的至少一种。本发明通过加入纳米材料，使得到的抗裂混凝土初期起强快，后期强度高，抗渗性能好，粘结强度高，有效提高混凝土的早期抗裂性能。
