SBS 2511 GA 3K 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 3K 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 3K 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 3K helps in increasing the mill output at same cement fineness.

GRINDING AID

2. Benefits
 Reduces grinding costs : The increased mill output with SBS 2511 GA 3K at
same cement fineness and energy consumption provides savings through lower
grinding costs per ton of cement.
 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%.
 Increases the flow ability of cement : The dry dispersive action of SBS
2511 GA 3K improves the cement flow ability characteristics.
 Improves the efficiency of the grinding process.
 Highly suitable to produce limestone / fly ash based cementitious system.
 Improved cement dry flow ability.
 Effective in low workability cement paste.
