In the cement industry, a large amount of energy is consumed in the grinding of raw materials and their clinker.

 

Grinding process, cement particle surface free charge density increases, the solid surface free energy increase, coupled with the collision between particles, particles increases the chance of reunion, adhesion, if cement particles further by trituration, you need to destroy the growing trend of reunion, adhesion, plus factors and the use of grinding aid is the most simple and convenient method, adding grinding agent less investment quick effect, and can effectively improve the physical quality of cement.

 

At present, domestic and international comparison of common organic material aid is alkanolamine and polyhydroxy alcohols, such as Triethanolamine, Diethanolamine, Polyethylene glycol, Triisopropanolamine and so on.

 

Triethanolamine is strong polarity of alcohol amine, alkaline aqueous solution, can chelate interaction between metal ions and minerals in the cement, with polyol compound, usually use of cement grinding effect to a certain extent, can quickly improve the early strength cement, but the late strength of cement decreased, the cost is higher.
