Product Description
Naphthalene superplasticizer high range water reducing admixtures
Product discription:This product is Sodium Naphthalene Sulphonate Formaldehyde (SNF) based water reducing agent,made of naphthalene,sulfonic acid,formalin and alkali,through sulphuration, hydrolyzation,condensation and neutralization reaction. It has the advantage of high water reducing ratio,non-delayed coagulation,non-air entraining and strong adaptability. It can improve the workability of concrete to a large extent so as to reduce the water consumption for blending. Meanwhile, it can improve the strength of concrete. In addition, as the main master batch of various kinds of compound concrete admixture, it could produce series products of concrete admixture which can be suitable for all kinds of project requirement through compounding with other kinds of admixture. This product can contribute to the improvement of project quality and construction efficiency and the reduction of construction cost.
Product picture:Application:1,Main ingredient is β-naphthyl sulfonate formaldehyde condensate
2,Good dispersion, water reduction and early-strength effect. It can speed up the turnover of templates and fields, accelerate construction progress and shorten the completion period. It is applicable for concrete with early-strength and high-performance requirements and other concretes that need to enhance strength and improve long term performance.
3,Increase the concrete slump and improve its liquidity, applicable for ready-mixed concrete, pumping concrete, high-liquidity concrete, grouting material, etc.
4,Without air entraining. It is applicable for all grades of concrete with steam curing condition and natural maintenance.
5,No corrosion on steel bars. It is applicable for precast concrete, cast-in-place concrete, reinforced concrete, prestressed reinforced concrete, etc. in various projects.
6,Good compatibility with portland cement, regular portland cement, portland slag cement, portland flyash cement, etc.
