FDN-AA early-strength superplasticizer is an non-chloride superplasticizer ,this products has high water reducing ,improving strength and early-strength .

It has good adaptability for different cement ,especially for slag and portland cement ,it is also better for producing concrete under low temperature. this product has no chloride ,no corrosion for steel.

▲Technical performance

1、The water reduce ration can be reached to 17% mix ,can produce big fluidity and high strength pumping concrete .

2、The technical data of result is better than standard o f GB8076-2008.

3、Has good adaptability for normal portland cement ,slag cement and fly ash cement .

4、Can dramatically improve impermeability and frost resistance of the concrete

5﹑ Less alkali content, alkali content can increase less than 1kg because of adding this admixture per CBM( one base of 400g for cementing material)

6 ﹑No corrosion for steel.

▲main function

This admixture is suitable to produce high strength, early strength and pumping concrete.

▲Method of usage

Added this admixture into the cement ,gravel and sand for remixing .if added later, the performance will be better.powder products should be properly stored in a dry place.if it has lumped because of humidity,even it is not effected to use,but it must be crushed  until the finesse meet the requirements before using.

▲Recommended range of dosage

Powder dosage will be 1.3-2.5% of cementing material .

Liquid dosage will be calculated according to recommended solid dosage and its solid content.

▲Packing & Storage:

1．The powdery product is packed in the waterproofing woven bag with plastic liner and the net weight is25Kg or 40KG per bag or 650MT per big bag .It doesn’t degenerate within its shelf life. The powdery product should be stored in dry and ventilated warehouse. Pay attention not to stave the bag and keep waterproofing during the storage and transportation. If it is affected with damp and agglomeration, it can be dissolved into liquid state or crushed into powder before using it and there is no influence on the performances.

2．The liquid product is sealed in plastic drums or metal drums to prevent accidental leakage and evaporation. And the net weight is 200Kg or 1000KG per drum. Also can be loaded into flexibag with net weight 20MT.
