Naphthalene-based Superplasticizers

KZJnazem RS86 and KZJnazem RR86 are ready to use liquid admixtures

Why has PNS/SNF high dispersion at low water/cement ratio and well adaptive to recycle aggregate materials in concrete.

The sulphonic groups of the polymer chains increase the negative charge of the cement particle surface and disperse these particles by electrical repulsion. This electrostatic mechanism causes the cementpaste to disperse and has the positive consequence of requiring less mixing water to abtain a given concrete workability. The rapid growth of hydration crystals will change the surface mechanical of the particles and set the free dispersion of them.

The average dosage of KZJnazem RS86 and KZJnazem RR86 are usually 1.0~2.5% based on cementitious materials situation, namely approximately 1.0– 2.5litre per 100 kg of cementitious material. Addition rates can vary with type of applications at deffirent temperatures and the optimum dosage may depend on the specific requirements of concrete and materials. At a given W/C ratio, the slump required for placement can be controlled by varying the addition rate.
