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

1. SBS 2511 GA(P)
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%.
 The increased mill output with SBS 2511 GA(P) at same cement fineness and
energy consumption provides savings through lower grinding costs per ton of
cement.
 Highly suitable to produce limestone/fly ash based cementitious system.
 SBS 2511 GA (P) is effective in both open circuit and closed circuit cement mills.
 Increased cement flow ability.
 Easy and safe handling.

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