CED 225 is a high efficiency strength improving grinding aid. It is particularly recommended for grinding cements. CED 225 reduces water demand for cement and concrete production, and gives increased early age mechanical strengths of cement.
• Mineral additive rates can be increased.
• Increase of early (24 and 48 hours) mechanical strengths of the cement.
• Cement strength profiles are improved.
• Allows a reduction in water demand in mortars.
• Increased mill production (8% to 15%) depending on the efficiency of the equipment and the characteristics of the material to be ground.
• Reduced grinding energy costs.
• Improved physical properties of the ground material.
• Improved performance in both closed and open circuit systems at equal specific surface area or equal sieve residues.
• Bulk density is increased.
• Powder flow characteristics are improved before, during and after storage.
• Packset tendencies and coating are substantially reduced.
• The risk of false set is reduced due to the lower grinding temperatures.
• Cement particle size distribution is improved resulting in more thorough hydration.
• Reduces plastic shrinkage (initial set).

Directions for use
Dosage: The dosage range is from 0.5kg to 0.8kg/ metric tone of material to be ground. Industrial trials are required to determine the optimum dosage.
Procedure: Liquid admixture ready-to-use. A dosing pump is required to introduce the correct dosage into the mill.
CED 225 may be introduced directly into the mill or onto the feed conveyor belt. Our technicians are ready to provide advice and assistance in the use of CED 225.
Health and Safety: If CED 225 comes into contact with skin, flush with water immediately.
Fire: CED 225 is non flammable.
Cleaning: Spillage of CED 225 can be removed with water (refer to Safety Data Sheet).
Overdose: Dosages in excess of 3kg/ metric tone should be avoided.
