Problems solved by technology

[0003] At present, the traditional mineral powder grinding aids usually use water, sodium lignin sulfonate and triethanolamine to ensure the fluidity of concrete. However, according to the needs of the construction environment, the fluidity of concrete should not be too strong, and it is still necessary to ensure a certain Therefore, people sometimes add industrial salt to speed up the hardening of concrete, and industrial salt is usually cheap and easy to obtain industrial waste salt, chemical by-product salt or untreated mineral salt, but the disadvantages are Contains more impurities, which will affect the hardening effect of mineral powder grinding aid on mineral powder, and cannot effectively improve the fluidity of concrete

Abstract

The invention discloses a mineral powder grinding aid for improving fluidity, the mineral powder grinding aid for improving fluidity is prepared from the following components in parts by weight: 30-32parts of water, 1-3 parts of anhydrous sodium sulphate, 7-8 parts of sodium thiosulfate, 5-6 parts of sodium nitrite, 4-5 parts of urea, 2-3 parts of lignosulfonic acid, 8-12 parts of triethanolamine, 23-27 parts of complex hydramine, 8-12 parts of glycerol, and 2-3 parts of sugar. The mineral powder grinding aid has a good grinding effect, less impurities and can improve the fluidity of concrete.

Description

technical field [0001] The invention relates to the technical field of mineral powder grinding, in particular to a mineral powder grinding aid for improving fluidity and a preparation method thereof. Background technique [0002] For the needs of concrete production and construction, an appropriate amount of mineral powder can usually be added to improve the fluidity of concrete. The increase of concrete fluidity can reduce the heat of hydration of concrete, improve the impermeability of concrete, increase the later strength, improve the internal structure of concrete, and improve the ability of impermeability and corrosion resistance. Concrete mixed with finely ground mineral powder can delay the hydration rate of cementitious materials and prolong the setting time of concrete. This property is beneficial to the transportation and construction of concrete in high temperature seasons. [0003] At present, traditional mineral powder grinding aids usually use water, sodium li...
