high performance ligte brown sodium salt of poly naphthalene sulfonate formaldehyde snf 24%

Product Overview

Description

SNFis made of naphthalene, sulfonic acid, formalin and alkali, through sulphuration, hydrolyzation, condensation and neutralization reaction. 

SNF have many advantage of :no chloride,good dispersion, water reduction and early-strength effect,good dispersion, water reduction and early-strength effect,without air entraining , no corrosion on steel bars , good compatibility with portland cement .

 Application

 

1   .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.

 

2   .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.

 

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

 

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