ARGICAL™ M-1200s

Supplied byImerys- Last Updated on Mar 31, 2026

ARGICAL™ M-1200s by Imerys is a kaolin based filler. It is an amorphous, pozzolanic silico-aluminate that is produced by calcining high-quality kaolin.
  • It prevents bleeding in flooring compounds and its excellent compatibility with common mortar components like binders, pigments and SCMs.
  • It enhances thixotropic products by increasing yield stress and reducing sagging.
  • ARGICAL™ M-1200s boosts mechanical strength through reactions with free lime and limestone, enhances durability by lowering porosity and reduces water absorption.
  • It also minimizes the risk of alkali-silica reactions, improves resistance to salts, chemicals and freeze or thaw cycles.
  • It decreases efflorescence in concrete and mortars by reducing free lime and works well with white and light-colored products.
  • ARGICAL™ M-1200s supports lean mix design by optimizing binder content, reducing CO2 emissions and contributing to cost savings in cementitious systems.
