The invention discloses a preparation method of a cement-based material with photocatalytic performance. The preparation method comprises the following steps: loading titanium dioxide sol obtained bya sol-gel method on the surface of a cement test block, putting the cement test block into a steam curing box, and carrying out steam curing to obtain a titanium dioxide crystal with an anatase structure on the surface of the cement test block, wherein the steam curing temperature is 50-100 DEG C, and the steam curing time is 2-48 hours. Compared with the existing internal mixing, external mixingand coating processes, the method disclosed by the invention not only has the advantages of material saving of titanium dioxide raw materials and good durability, but also realizes crystallization oftitanium dioxide while cement steam curing, and has certain energy-saving and environment-friendly properties.
本发明公开了一种具有光催化性能水泥基材料的制备方法，将溶胶‑凝胶法获得的二氧化钛溶胶负载在水泥试块表面，将水泥试块放入蒸养箱内，蒸汽养护后，水泥试块表面得到具有锐钛矿结构的二氧化钛晶体；蒸汽养护的温度为50℃～100℃，蒸汽养护的时间为2h～48h。相比于现有的内掺、外掺、涂敷工艺，本发明方法不但具有二氧化钛原材料用料节省、耐久性好的优点，而且在水泥蒸汽养护的同时实现了二氧化钛的结晶，具有一定的节能环保性。
