CED 224 is a grinding aid which is specifically formulated to increase, in specific cases, the early age mechanical strengths of cement.
• Increase of early (24 and 48 hours) mechanical strengths of the cement.
• Increased mill production (8% to 14%) 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).
• Form : Liquid.
• Active ingredients : Aqueous solution of organic and mineral components.
• Specific gravity at 20°C : 1.330 kg/ dm3 (± 0.015).

• Chloride content : 16% (± 1).
• Alkali content : 2% Na2O equiv.
Other characteristics
• Colour : Light brown.
• Freezing point : < -10°C.
• Flash point : Non flammable product.
• Dry matter (solids content) : 43%.
Packaging
• Bulk tanker loads (where appropriate).
• 1000 liter containers and 215 liter drums.
Storage
The quality is guaranteed for 12 months starting from the manufacturing date provided the product is not altered with other chemicals. Do not mix with any other product.
CED 224 will not freeze above -10°C.
• Grinding of cements according to ENV 197 - 1, type I to V.
• The use of CED 224 is especially recomended for the manufacture of rapid hardening cement.
Method of use
Dosage : The dosage range is from 1.2kg to 2.5kg/ 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 224 may be introduced either directly into the mill or onto the feed conveyor belt.
Our technicians are ready to provide advice and assistance in the use of CED 224.
Health and Safety : If CED 224 comes into contact with skin, flush with water immediately.
Fire : CED 224 is non flammable.
Cleaning : Spillage of CED 224 can be removed with water (refer to Safety Data Sheet).
Overdose : Dosages in excess of 3kg/ metric tone should be avoided.
