Namex® XA
Mineral additive for the reduction of thermal shrinkage in cement-bound building materials
Namex® XA is a reactive mineral additive for cement-bound building materials. The mineral blend, ground to cement fineness, reacts with the mixing water under a volume increase. This expansion can counteract thermal shrinkage caused by restraint stresses and contribute to a reduced shrinkage magnitude.
