Cement mortar with carbon sequestration and self-curing functions and preparation method thereof
The invention discloses cement mortar with carbon sequestration and self-curing functions. The cement mortar is prepared from the following components in parts by weight: 300 to 350 parts of cement, 375 to 400 parts of modified lithium slag/nano titanium dioxide slurry and 1200 to 1350 parts of sand, wherein the modified lithium slag/nano titanium dioxide slurry is prepared from the following components in parts by weight: 240 to 260 parts of modified nano titanium dioxide liquid and 100 to 125 parts of modified lithium slag powder; the modified nano titanium dioxide solution is an aminated modified nano titanium dioxide solution; the modified lithium slag powder is lithium slag powder modified by a polycarboxylic acid water reducing component. According to the invention, the nano titanium dioxide is subjected to composite amination modification, the lithium slag powder is modified by using the polycarboxylic acid water-reducing mother solution, and then the nano titanium dioxide and the lithium slag powder are stably compounded and introduced into a cement mortar system, so that the carbonization-hydration synergistic effect can be promoted, the overall performance of the cement mortar can be effectively improved while carbon sequestration is realized, and the curing conditions can be simplified; popularization and application are facilitated.
本发明公开了一种具有固碳和自养护功能的水泥砂浆，各组分及其所占重量份数包括：水泥300～350份，改性锂渣/纳米二氧化钛浆液375～400份，砂1200～1350份；其中，改性锂渣/纳米二氧化钛浆液中各组分及其所占重量分数包括：改性纳米二氧化钛液240～260份，改性锂渣粉100～125份；所述改性纳米二氧化钛液为胺化改性纳米二氧化钛液；改性锂渣粉为聚羧酸减水组分改性的锂渣粉。本发明首先对纳米二氧化钛进行复合胺化改性，利用聚羧酸减水母液改性锂渣粉，然后将二者进行稳定复合，并引入水泥砂浆体系中，可促进实现碳化‑水化协同效应，在固碳的同时有效提升水泥砂浆的整体性能，并可简化养护条件，适合推广应用。
