SikaGrind® GA 1311

High Performance Cement Additive to Increase Grinding Efficiency and Inhibit Pack Set of Cement

SikaGrind® GA 1311 is specially formulated as a high-performance grinding aid and pack set inhibitor for Portland cement and other hydraulic cements. It is based on modified hydroxylated compound mixtures.
SikaGrind® GA 1311 is compatible with all types of cement.

SikaGrind® GA 1311 effectively reduces the agglomeration between cement particles inside the cement mill. It is one of the most effective dispersants that improves the efficiency of grinding process by reducing the surface energy forces of cement particles and creating electrostatic repulsion between cement particles. This phenomenon contributes to the following:
  • Boost up clinker breaking property effectively.
  • Increased cement mill output at the same cement fineness from 8% to 30%.
  • Reduced total cement grinding costs per ton of cement.
  • Improved cement strength by improving the cement particles size distribution.
  • Improved cement dry flowability.
  • Reduced cement mill grinding temperature which can help in maintaining the quality of cements.

Application

Consumption

Recommended Dosage

The typical dosage rate for SikaGrind® GA 1311 is as per the table below:

Type of Cement Blaine Surface Area (cm2/gram)    Dosage Rate
(gram/ton) 
Ordinary Portland 2800- 3200 150-300
Ordinary Portland 3200-3500 200-400
Other Hydraulic cements 3500-4000 200-400
Other Hydraulic cements                          >4000 300-500

The grindability of cement is influenced by the chemical and physical composition of the basic ingredients of the cement, grinding process and clinker characteristics. Trial at the laboratory scale is recommended to determine the optimum dosage required to achieve any specific requirement.
Application steps

APPLICATION

SikaGrind® GA 1311 can be added at the clinker feed conveyer belt or directly into the cement mill’s first compartment. A proper dosing pump is required to ensure the correct dosage into the cement for obtaining the optimum performance.
