naphthalene powder superplasticizer ST-02A 2015 New water reducer powder form Concrete

Sodium Naphthalene Sulfonate Formaldehyde Concrete Agent has the characteristics of retarding, super-plasticized, water-reducing, less loss of slump. It is very effective concrete admixture to adopt in high temperature area.

Excellent effect of retarding: It can be used in retarding the setting of concrete for 2 hours to 36hours, and initial setting and ultimate hardening almost happen at the same time, so that it’s convenient for conveying at long distance.

With the water-reducing rate of 15%-25%, it can improve the flowability, permeation-proofing ability, and the workability of concrete, concrete compression resistant, and other physical mechanics will be also gained.

Reduces cement dosage by 15%-25% without altering compression strength and slump.

Good for many applications: Portland cement, ordinary Portland cement, Portland fly-ash cement, Portland pozzolana cement and Portland blast furnace-slag cement.
