Anti-seepage and anti-corrosion concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to anti-seepage and anti-corrosion concrete and a preparation method thereof. The concrete product developed by the method comprises cement and graphene oxide of which the mass is 10-15% of that of the cement, a polymer is deposited between the graphene oxide layers; the molecular structure of the polymerhas an amidine group; and the amidine group is positioned on the side chain of the polymer molecular chain. The polymer is formed by in-situ polymerization of a monomer between the graphene oxide layers; in addition, the concrete also comprises a chelating agent; and the chelating agent is deposited between the graphene oxide layers. In the actual use process, the obtained product has excellent anti-seepage and anti-corrosion performance, and the service life of concrete can be effectively prolonged.
本发明属于建筑材料技术领域，具体涉及一种防渗、防腐蚀混凝土及其制备方法。本发明研制的混凝土产品中，包括水泥，水泥质量10‑15％的氧化石墨烯；所述氧化石墨烯层间沉积有聚合物；所述聚合物分子结构中带有脒基团；所述脒基团位于聚合物分子链侧链。其中，所述聚合物是由单体在所述氧化石墨烯的层间原位聚合形成；另外，所述混凝土中还包括螯合剂；所述螯合剂沉积于氧化石墨烯层间。本发明所得产品在实际使用过程中，具有优异的防渗防腐蚀性能，可有效延长混凝土的使用寿命。
