NIROGRIND AD400

Cement Grinding Aid for enhancement of cement early strength and reduction of unit grinding energy

Description

NIROGRIND AD400 is a liquid, ready-to-use cement grinding aid designed to enhance the early strength of cement and to improve the efficiency of the grinding process by reducing the surface energy forces.

It also improves the flow characteristics of cement with positive impact on cement conveyance and reduction of pack-set in storage.

NIROGRIND AD400 is effective in both open circuit and closed-circuit cement mills.

It is compatible with all types of cement and complies with ASTM C465-99 as a nonharmful processing additive.

USES

  • Ordinary Portland cement
  • Blended cement with limestone, fly ash or slag.

The special characteristics of NIROGRIND AD400 effectively activate the hydration process between cement particles and the non-reactive or reactive fillers.

For additional information on NIROGRIND AD400 and its use in developing special performance characteristics, contact your local Nirman Chemicals Limited sales field representative.

ADVANTAGES

  • Mineral additive rates can be increased.
  • Increase of early (24 and 48 hours) mechanical strengths of cements.
  • Increases mill production (8% to 15%) depending on the efficiency of the equipment and the characteristics of the material to be ground.
  • Reduces grinding energy costs.
  • Improves physical properties of the ground material.
  • Improves performance in both closed and open circuit systems at equal specific surface area or equal sieve residues.
  • 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 lower grinding temperature.
  • Cement particle size distribution is improved resulting in more thorough hydration.
  • Reduces plastic shrinkage (Initial set).
