This article presents a short overview of modified cements with photocatalytic activity. First, the types and three main methods of obtaining photoactive cements are presented. The most frequently used modification method is the incorporation of a photocatalyst into the total mass of the cement. The second group analyzed is cements obtained by applying a thin layer of photoactive materials, e.g., paints, enamels, or TiO suspensions, using various techniques. The third group is cement mortars with a thick layer of photoactive concrete on the top. In addition, methods for determining the photoactivity of cement composites, mechanical properties, and physicochemical parameters of such materials are briefly presented. Finally, examples of investments with the use of photoactive cements and development prospects are shown.

本文简要概述了具有光催化活性的改性水泥。首先，介绍了光活性水泥的类型及三种主要制备方法。最常用的改性方法是将光催化剂掺入水泥的总质量中。分析的第二组是通过使用各种技术涂覆一层薄的光活性材料（如涂料、搪瓷或TiO悬浮液）而获得的水泥。第三组是顶部有一层厚光活性混凝土的水泥砂浆。此外，还简要介绍了测定水泥复合材料光活性、力学性能及此类材料物理化学参数的方法。最后，展示了使用光活性水泥的投资实例及发展前景。
