The Application of Triethanolamine & Triisopropanolamine in Slag cement


Slag cement has the advantages of low heat of hydration, high strength in the late stage, inhibition of alkali aggregate reaction and sulfate resistance. It has been applied in a large number of projects. 

In the produce process  of slag cement, the slag is not easily grind than the clinker,  If grinding two materil together can not reach their optimum active particle size, and separate grinding will cause a lot of energy consumption, so the grinding process used Grinding aids to reduce grinding energy consumption and improve cement performance. 


Triethanolamine (TEA) and triisopropanolamine (TIPA), as the main components of common grinding aids, have strong polarity and can reduce the free energy on the surface of cement particles to prevent the agglomeration of particles and increase the particle size and  specific surface area, Beside  also accelerate the rate of hydration of clinker minerals, it has been widely concerned by scholars from China domestic  and abroad. Previous studies mainly focused on the effect of alcohol amine organic compounds and their modified compounds on the cement grinding effect. There are still few studies on the mechanism of TEA and TIPA affecting the hydration of slag cement. Therefore, The Chinese scholars do a experiment.The TEA and TIPA were chosen as grinding aids to discuss the hydration process of slag cement under the action of TEA and TIPA, which provided a basis for the application of TEA and TIPA in slag cement.
