Problems solved by technology
The flowability of ground fly ash is generally poor due to the grinding or breaking of some of the spherical microbeads of fly ash
[0003] Grinding aids have been widely used in the grinding process of fly ash. The role of various grinding aids is mainly to improve the grinding efficiency, such as increasing the fineness of fly ash under the same mill output or maintaining the same fineness. However, traditional grinding aids cannot improve the fluidity of fly ash, resulting in that the quality of ground fly ash is usually much lower than that of directly discharged fly ash of the same fineness, and the price is low and economical. Not efficient

The invention provides a grinding aid material for improving the fluidity of fly ash, and a use method thereof. According to the present invention, the grinding aid material is prepared from a surfactant and polyacrylamide; the grinding aid material is dissolved in water to prepare a grinding aid material aqueous solution, and the grinding aid material aqueous solution is sucked out of a containerby using a high pressure water pump, is introduced into a mill, and is completely mixed with fly ash, such that the grinding aid material can be attached to the surface of the fly ash particles to form a film layer, and the fluidity of fly ash concrete can be improved by using the lubricating effect on the fly ash spherical particles after the dissolving of the film layer when the fly ash and cement are mixed; and the grinding aid material has advantages of extremely low consumption, extremely low cost and convenient use.
Description
technical field [0001] The invention relates to a grinding aid material for improving the fluidity of fly ash and its application method. Background technique [0002] Fly ash has been widely used to replace part of cement to prepare concrete. It can improve the fluidity of concrete and increase the lubrication of concrete and pump pipes through the "ball effect" produced by a large number of spherical microbeads, which is convenient for pumping. However, the fineness of fly ash discharged by many power plants is not up to the standard, and it needs to be ground before it can be used. The fluidity of finely ground fly ash is generally poor because some of the spherical microbeads of fly ash are ground or broken. [0003] Grinding aids have been widely used in the grinding process of fly ash. The role of various grinding aids is mainly to improve the grinding efficiency, such as increasing the fineness of fly ash under the same mill output or maintaining the same fineness. ...
