Modified cement mortar as well as preparation method and application thereof
The invention discloses modified cement mortar as well as a preparation method and application thereof. The modified cement mortar is prepared from the following raw materials in parts by weight: 20 to 30 parts of cement, 70 to 80 parts of nano TiO2 hydrosol coating sand and 8 to 12 parts of water. Wherein the nano TiO2 hydrosol coating sand is prepared by soaking natural sand subjected to hydroxylation treatment in nano TiO2 hydrosol and then drying; the TiO2 hydrosol comprises the following raw materials: titanium tetraisopropoxide, absolute ethyl alcohol, acetic acid and water in a volume ratio of (2-3): (7-8): (1.5-2.5): (35-45). The dispersity of nano TiO2 in a cement mortar matrix is greatly improved, firstly, TiO2 which is better dispersed is used as a nano filler to remarkably improve an interface transition area between cement and sand, and the mechanical property of the cement mortar is greatly improved; secondly, the modified mortar has a photocatalytic self-cleaning function, and rhodamine B organic dye and NO harmful gas can be effectively degraded.
本发明公开了一种改性水泥砂浆及其制备方法和应用，该改性水泥砂浆包括以下重量份的原料：水泥20‑30份、纳米TiO2水溶胶涂层砂70‑80份、水8‑12份；其中纳米TiO2水溶胶涂层砂由经羟基化处理的天然砂浸泡纳米TiO2水溶胶后烘干制得；TiO2水溶胶包括以下体积比原料：四异丙醇钛：无水乙醇：乙酸：水为2‑3：7‑8：1.5‑2.5：35‑45。本发明中纳米TiO2在水泥砂浆基体中的分散性得到了极大的改善，首先，分散更好的TiO2作为纳米填料显著改善了水泥与砂子之间的界面过渡区，极大的提升了水泥砂浆的力学性能；其次，改性后的砂浆具有光催化自清洁功能，可有效地降解罗丹明B有机染料和NO有害气体。
