普通的水泥混凝土用聚合物浸渍之后,其强度可以成倍地增长,而且具有抗渗、抗冻、抗化学腐蚀等极好的性能,所以这种混凝土(简称PIC)自六十年代后期开始兴起以来受到了广泛的重视。它通常采用某种液体的有机单体,随后通过加热或辐射的方法使单体转化成聚合物,后者在混凝土的孔隙中与水泥相互交错构成复合体。从试验中的 Ordinary cement concrete has been impregnated with a polymer, its strength can be multiplied, and has excellent properties such as impermeability, frost resistance and chemical resistance, so this kind of concrete (referred to as PIC) has been on the rise since the late 1960s Has been widely valued. It usually uses a liquid organic monomer followed by heating or radiation to convert the monomer into a polymer that interlaces with the cement in the pores of the concrete to form a composite.
