SBS 2511 GA(S) is 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(S) 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(S) 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(S) helps in increasing the mill output at same cement fineness.

2. Benefits
 Increased early and long- term compressive strengths for production of better
quality cement.
 Reduced cost of cement production through reduced unit grinding cost and
through replacement of clinker with reactive additions such as pozloans, blast
furnace slag and fly ash or filler such as lime stone.
 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 the rate of hydration of cements.
 Effective in low workability cement paste.
 Easy and safe handling

3. Description
SBS 2511 GA(S) is 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(S) 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(S) 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(S) helps in increasing the mill output at same cement fineness.

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