General description

Triisopropanolamine (TIPA), a tertiary alkanolamine, is majorly used as a grinding chemical that reduces agglomeration in the ball milling process and changes the particle distribution of the finished cement.

Application

TIPA can act as an interfacial transition zone (ITZ) to improve the mechanical properties of the mortar and the concrete. It can also be used to increase the compressive strength of the cement-fly ash system by accelerating the hydration of both the compounds.
