Admix P

Integral Waterproofing Admixture for Mortar and Concrete

Product Description

Admix P is a powder admixture made from special hydrophilic components which, when added to a concrete mix, reduces the permeability of hardened concrete.

Field of Application

Admix P may be used with any type of concrete when a reduction of permeability is required. Once Admix P is added to the mix, it reacts with water during the entire service life of the concrete. Admix P may be used to make concrete that is resistant to aggressive environments. The specified exposure class of the concrete must always be respected and the product cannot be used to make up for poorly designed concrete. To have guaranteed results, Admix P must only be used in concrete that has been correctly designed respecting two basic rules for the production of impermeable concrete, which are, a water/cement ratio of 0.45 and an adequate wet curing time. Admix P may be successfully used to produce concrete for the following applications:

• dams;

• bridges;

• car parks;

• storage tanks;

• pipes and piles;

• retaining walls;

• tunnels;

• marine structures;

• basements and foundations;

• swimming pools;

• precast elements;

• “white tanks”
