本发明公开了一种水泥助磨剂及其制备方法，它是将纳米CaCO3，纳米SiO2，三乙醇胺，甲酸钙和羧基羧酸混合均匀后研磨成粉制成。该助磨剂加入水泥后，可有效提高水泥生产中工业废渣的掺入量，增强水泥强度，优化混凝土密实度进而改善混凝土耐久性，改善水泥和易性，节能环保效果显著，具有良好的市场应用前景。The invention discloses a cement grinding aid and a preparation method thereof, which is prepared by mixing nanometer CaCO 3 , nanometer SiO 2 , triethanolamine, calcium formate and carboxycarboxylic acid and grinding them into powder. After the grinding aid is added to cement, it can effectively increase the amount of industrial waste slag mixed in cement production, enhance the strength of cement, optimize the compactness of concrete and then improve the durability of concrete, improve the workability of cement, and have remarkable energy-saving and environmental protection effects. It has a good market Application prospect.
Description
Technical field
The invention belongs to the cement additire technical field, be specifically related to a kind of cement grinding aid and preparation method thereof.
Background technology
To improve the tube mill operating efficiency in order reaching, to reduce production costs, increase the purpose such as output, in cement production process, particularly in the cement process, usually need to add certain grinding aid. Although existing grinding aid is various in style, also have many problems: the 1. cement grinding aid take organic matter as main component (such as triethanolamine etc.), because high cost, manufacturer is beyond affordability. Also there is the problem that is difficult to evenly sneak into cement in such grinding aid simultaneously, affects product quality. 2. the cement grinding aid take inorganic matter as main component is (such as Na2SO
4, NaCl etc.). Such grinding aid mainly works to cement early strength, but inoperative to the strength of cement of (containing 28 days) after 28 days, even can cause the strong retraction of cement. The use of such grinding aid is in a single day excessive, can work the mischief to concrete durability. 3. the compound grinding aid of inorganic matter and organic matter is (such as Na2SO
4Compound with triethanolamine). Such grinding aid is by above-mentioned two kinds of composite forming of grinding aid, and the unresolved problem that it exists separately. Therefore, how to overcome the defective of the said goods, provide a kind of effect cement grinding aid remarkable, with low cost, just become difficult problem that needs to be resolved hurrily in the prior art.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of cement grinding aid is provided, the waste residue incorporation in the Effective Raise manufacture of cement satisfies the energy-saving and environmental protection requirement of enterprise.
The present invention also aims to provide a kind of method for preparing above-mentioned cement grinding aid.
Purpose of the present invention is achieved by following technical scheme.
Cement grinding aid of the present invention is made by the raw material of following weight parts: nanometer CaCO340～60 parts, nanometer SiO210～30 parts, 3～5 parts of triethanolamines, 20～30 parts of calcium formates, 1～3 part of carboxyl carboxylic acid.
Cement grinding aid of the present invention is made by following methods: pulverize after the raw material of above-mentioned weight portion is mixed, namely get this grinding aid.
In the process of grinding cement, with this grinding aid by weight percentage be that 0.6%～1% ratio adds in the cement, but the incorporation of industrial residue in the Effective Raise manufacture of cement, refinforced cement intensity, optimize concrete density and then improve concrete durability, improve the cement workability, have significant effects of energy conservation and environmental protection. This cement grinding aid after testing, all indexs all reach building material industry standard, have good market application foreground.
The specific embodiment
Below in conjunction with embodiment and Application Example the present invention is described in further detail, but they are not limitation of the invention.
