Embodiment 1

[0021] The raw materials used in this embodiment and their ratio are: 100% mixed slag, 75% of high-titanium blast furnace slag, and 25% of ordinary slag. The remaining components are calculated according to the mass percentage of mixed slag, including the following components and proportions: metakaolin 2.5%, fly ash 1.5%; water glass 0.3%, caustic soda 0.15%; ethylene glycol 0.02%, methyldiethanolamine 0.005% .

[0022] Pre-mix the water glass, caustic soda and metakaolin weighed in proportion, wherein the specific surface area of ​​metakaolin is not less than 200m 2 / kg; Ethylene glycol and methyldiethanolamine are slowly and evenly added to the above mixture, after mixing evenly, let it stand and age for not less than 1 hour to obtain the activator.

[0023] The samples were prepared according to the requirements of "Granulated Blast Furnace Slag Powder Used in Cement, Mortar and Concrete" (GB / T 18046-2017). After curing to the corresponding age, the test results are shown...

Embodiment 2

[0025] The specific implementation process is the same as in Example 1, the difference is that the proportion of mixed slag used is different, specifically, the high-titanium blast furnace slag is 83%, and the common slag is 17%;

Embodiment 3

[0027] The specific implementation process is the same as in Example 1, the difference is that the amount and proportion of the silicon-aluminum materials used are different, specifically, 4.8% of fly ash.

Abstract

The invention discloses an activating agent for S75-grade high-titanium slag micropowder. The activating agent is characterized by being prepared from the following components in proportion: an exciting agent, a silicon-aluminum material and a grinding aid component, wherein the sum of the mass of the components is 1, and based on the mass of the mixed slag, the proportions of the other materialsare as follows: 3.2%-5% of the silicon-aluminum material, 0.25%-0.5% of the exciting agent and 0.02%-0.04% of the grinding aid component. By implementing the activating agent, the efficient resource utilization path of the high-titanium blast furnace slag is expanded, a new design thought is provided for solving the problems of low activity and high grinding power consumption of the high-titaniumblast furnace slag, the process is simple and easy to implement, outstanding technical advantages and economic benefits are achieved, and the large-scale application and popularization potential is huge.

Description

technical field [0001] The invention relates to an activator for S75 grade high-titanium slag micropowder, which belongs to the field of concrete materials. Background technique [0002] Different from ordinary slag, high-titanium granulated blast furnace slag (hereinafter referred to as high-titanium blast furnace slag) has a high titanium content, so it forms a polycrystalline composite structure with perovskite as the main crystal mineral and an extremely complex intercalation relationship. , stable chemical properties, activity index is far lower than ordinary slag. Titanium is a very precious resource. Therefore, researchers focus on the development and utilization of titanium in the extraction and recovery of high-titanium blast furnace slag. Generally, physical-chemical methods are used to enrich titanium in a certain ore. phase (mainly perovskite), and then through the combination of separation and smelting, the high titanium slag is further used to extract titanium...
