High-titanium slag ultra-high performance concrete and preparation process thereof
The invention relates to the field of concrete, aims to solve the problems of energy conservation and carbon reduction of ultra-high performance concrete (UHPC), recovery and utilization rate of industrial waste residues and waste glass and the like, and provides high titanium slag ultra-high performance concrete which comprises the following components in parts by weight: 1567-1717 parts of high titanium slag sand, 483-541 parts of cement, 70-175 parts of activated glass powder, 65-79 parts of fly ash, 64-78 parts of silica fume, 79-86 parts of steel fibers, 20-28 parts of a water reducing agent and 0.2-1 part of a defoaming agent. The preparation process of the activated glass powder comprises the following steps: S100, sequentially carrying out a crushing process and a grinding process on glass to obtain glass powder; s200, weighing 70-175 parts by weight of glass powder and 11.8-28.4 parts by weight of an activating agent, uniformly mixing, adding 12-32 parts by weight of water, and finally aging for 3-5 days in an environment with the temperature of 20-25 DEG C and the humidity of 40-60% to obtain initially activated glass powder; and S300, performing hydrothermal activation on the initially activated glass powder at high temperature and high pressure, and drying to obtain the activated glass powder. Through a comprehensive activation method, the waste glass powder is subjected to activity excitation in advance, so that the volcanic ash activity and the filling effect can be exerted to a greater extent.
本发明涉及混凝土领域，用以解决超高性能混凝土(UHPC)节能降碳，工业废渣及废旧玻璃回收利用率等问题，提供了高钛矿渣超高性能混凝土，以重量份计，包括：高钛矿渣砂1567～1717份、水泥483～541份、活化玻璃粉70～175份、粉煤灰65～79份、硅灰64～78份、钢纤维79‑86份、减水剂20～28份、消泡剂0.2～1份；所述活化玻璃粉的制备工艺包括如下步骤：S100、玻璃依次通过破碎工序、研磨工序得到玻璃粉；S200、以重量份计，称取70～175份玻璃粉和11.8～28.4份激活剂混合均匀后，加入12～32份水，最后在温度20～25℃、湿度40％～60％的环境下陈化3～5天，得到初激活玻璃粉；S300、初激活玻璃粉在高温高压下水热活化后烘干，得到活化玻璃粉。本发明通过综合活化法，将废玻璃粉提前进行活性激发，使其能够更大程度发挥火山灰活性和填充效应。
