This document describes a grinding aid called SBS 2511 GA 3L. It is a non-chloride aqueous solution that improves cement grinding efficiency, increases cement strength, and improves flowability. It reduces agglomeration during grinding, allowing for increased mill output and strengths up to 25% higher with average strength gains of 10%. It is suitable for use in portland and other hydraulic cements, especially with hard clinkers.

GRINDING AID

2. Benefits
 Increase grinding efficiency increased mill output, higher cement finess
and/or reduced unit power input and grinding costs.
 Increases compressive strength and flexural strength of cement:
Increases as high as 25% are not uncommon however the average of all
tests for all ages is 10%.
 Highly suitable to produce limestone/fly ash based cementitious system.
 Increased early and long- term compressive strengths for production of better
quality cement.
 Improved cement dry flow ability.
 Effective in low workability cement paste.
 Easy and safe handling.

3. Description
SBS 2511 GA 3L is a non-chloride based an aqueous solution of an amine acetate salt
and is an effective dispersant particularly developed for use as a grinding aid for Portland
cement and other hydraulic cements. SBS 2511 GA 3L conforms to ASTM C 465. It
helps in improving the efficiency of the grinding process by reducing the surface energy
forces that causes agglomeration of the newly fractured cement particles. It is effective in
both open circuit and closed circuit cement mills. The improved flow ability of cements
with SBS 2511 GA 3L results in faster loading and unloading times of bulk tankers. Also,
it helps in increasing the bulk density of cement and helps in providing increased storage
capacities of silos and bulk tankers. However, it is recommended to dilute with 5 parts of
water or more to ensure greater proportioning accuracy and better additive
distribution. SBS 2511 GA 3L helps in increasing the mill output at same cement
fineness.

4. Uses
SBS 2511 GA 3L is used as a grinding aid for Portland and other hydraulic
cements. The special characteristics of SBS 2511 GA 3L allows it to be
effectively used in the cement plants that constantly have problems with
hard and hot clinkers.
