普通混凝土是一种非均质、多孔材料,存有抗渗、抗冻、耐腐蚀等性能差的弱点,因此,其使用范围受到一定的限制。多年来,世界各国对水泥混凝土的改性工作进行了大量的研究,先后对水泥混凝土采用掺加聚合物和用单体浸渍后聚合等方法改善和提高它的抗渗、抗冻和耐腐蚀性能,取得了较好的效果,但是工艺比较复杂,成本较高,给广泛应用带来一定的困难。 Ordinary concrete is a kind of non-homogeneous and porous material, and it has weak points such as impermeability, anti-freezing, and corrosion resistance. Therefore, its use range is limited. Over the years, various countries in the world have conducted a lot of research on the modification of cement concrete, and successively improved and improved its impermeability, antifreeze, and corrosion resistance by adding polymer to cement concrete and polymerizing by using monomers. Achieved better results, but the process is more complex and the cost is higher, which brings certain difficulties to a wide range of applications.
