ca. 1,5% (+/- 0,5%)


Also available in liquid.


Sodium Naphthalene Sulfonate Powder is a mild-alkaline, light brown poly-naphthalene sodium salt and a classic flux in building chemistry.

Depending on the prerequisite, it can be used to improve the rheological and mechanical properties of concrete (workability, compressive strength and flexural strength, modulus of elasticity).

By dispersing the cement particles and breaking the cement agglomerates, for example, the use of water (reduction in the water-cement ratio of up to 30%) is reduced, which is necessary in particular in the case of high-strength concretes.

In addition, naphthalenesulfonates, e.g. influence the fluid self-leveling and the early strength.

The effect and dosage depends on the temperature, type and brand of the cement, the type of aggregates, the method of mixing and transport.
