GRINDING AIDS: A STUDY ON THEIR MECHANISM OF ACTION. Bravo Anna, Cerulli Tiziano, Giarnetti Mariagrazia, Magistri Matteo. Mapei S.p.A., via Cafiero 22, 20158 Milano, Italy. E-mail: dam_cafmapei. ABSTRACT. Most of the recent works  on cement additives focused the attention on their effectiveness on.
Effects of modified triethanolamine as cement grinding aids on particles characteristics and mechanical property of cement were studied, and its reaction mechanism was analyzed by IR, Zeta potential,.
Reported mechanisms explaining such effects are analyzed and possible ways to improve the grinding effi- ciency, through the use of chemical additives, are also discussed.

Grinding aid / pack set inhibitor. PRODUCT DATA SHEET. Product Description. HEA2® is an aqueous solution of an amine acetate salt with the following specifications: HEA2 is one of the most effective dispersants yet developed for use as a grinding aid/pack set inhibitor for portland cement and other hydraulic cements.
But the effect mechanism of the grinding aids is divided, and the grinding effect of the system is still need to be improved. In this paper, the development history of cement grinding aids is introduced, and the grinding aids are summarized systematically from the aspects of the grinding mechanism and present research.

1 Introduction. Grinding aids have been used successfully for decades in cement production and many other areas, such as ceramics, pigments etc. The main effect is to reduce energy consumption and increase the grinding efficiency. Additional features can be improved – e.g. powder flowability and strength development.
