TAVERO HEA2. TAVERO HEA2 Visit TAVERO HEA2 page. Description. 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. HEA2 greatly improves the efficiency of the grinding process by reducing the surface energy forces which cause agglomeration of the newly fractured cement particles.
particularly high dosages of grinding aids. With commercial grinding aids containing PCEs, such as SikaGrind-820, -840 and -870, the dosages typi-cally used in cement production are not sufficiently high for a measurable effect. The majority of commercial grinding aids
Jun 01, 2018 The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles.
