Amino Acrylsulphonate Phenol Formaldehyde Condensate Concrete Admixture

Amino Acrylsulphonate Phenol FormaldehydeCondensate Concrete Admixture, AS Type

AS type amino acrylsulphonate phenolformaldehyde condensate concrete admixture is amino superplasticizer, featuring non-air-entraining, highenhanced, low dosage, low slump loss, low alkali content, greatly reducedplastic viscosity of concrete, more than 30% of high water reducing rate, etc.With low alkali content, it can avoid concrete alkali-aggregate reaction and ithas no precipitation and no crystal when used in winter. Also, it is wellcompatible with various Portland cement, and it can provide good volumestability, impermeability and frost resistance to ensure high durability ofconcrete. With high early strengthening, our product can reach above 70% of thedesign strength grade by 3 days.

Our amino acrylsulphonatephenol formaldehyde condensate concrete admixture can be widely used to producehigh fluidity concrete, high strength concrete, no-vibration andself-compacting concrete, especially mass concrete and pumping concrete forlong-time and long-distance transport. With good steam curing adaptability, itcan be also applied for precastconcrete production in industrial and civil buildings and municipalengineering. In addition, our product can meet the needs of differentengineering for concrete performance and construction conditions if complexed with admixtures such asnaphthalene superplasticizer,air-entraining agent, retarding agent, early strengthening agent, expandingagent, anti-freezing agent and so on.
