Superplasticizer

Know-how Transfer

Specialized Production Line for AK Superplasticizer Powder (Turn-key Project)

Product Description
acetone-formaldehyde resin(AK), is a kind of anionic aliphatic macromolecular surface active substance which is derived from acetone, formaldehyde and sulfonating agent with alkalic catalysis.AK is a high range water reducer, commonly referred to as a superplasticizer. AK contains no chloride.

AK meets the requirements of chemical admixture specifications for concrete: ASTM C494 as Type F.

Application
It’s widely used in making concrete pumping agent. It’s also compounded with naphthalene superplasticizer or amino-based superplasticizer to compound special admixture featuring retarding, accelerating, anti-freezing, air-entraining effect, etc. It wins more and more market favor now.

Features
1.Water reducing rate of over 20%, no air entraining effect, no corrosion to steel bars and notable strengthening effect.
2.Recommended dosage: 1.5% by weight of cementitious materials.
3.Good compatibility to common Portland cement.
4.No crystallization and deposit in winter time.
5.No pollution during production, pro-environment, low investment and easy operation.
