DEX 110 is a high efficiency, strength improving grinding aid. It is particularly recommended for grinding cements. DEX 110 reduces substantially water demand for cement and concrete production, and gives increased mechanical strengths of the cement.
• Mineral additive rates can be significantly increased.
• Cement strength profiles are improved.
• Allows measurable reduction in water demand in the order of 1-2 %.
• Increased mill production (10% to 25%) 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.
• Pack set 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 1.2kg to 2kg/ 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.
Overdose: Dosages in excess of 3kg/ metric tone should be avoided.
Our technicians are ready to provide advice and assistance in the use of DEX 110 may be introduced directly into the mill or onto the feed conveyor belt.
Health and Safety: If DEX 110 comes into contact with skin, flush with water immediately. In case of contact with eyes, flush with water immediately and rinse with diluted boric acid solution, seek medical advice.
Fire: DEX 110 is non flammable.
Cleaning: Spillage of DEX 110 can be removed with water (refer to Safety Data Sheet).
