    Description

    SMF is a soluble melamine formaldehyde resin based superplasticizer. It has no air-entraining. A chloride free admixture based on melamine formaldehyde, formulated for the production of rheoplastic concrete. Available as a liquid, or in powder form which must be dissolved in water prior to use.

    A rheoplastic concrete is a fluid, but cohesive mix with a slump value of at least 200mm. It is virtually self compacting, but at the same time free from segregation and with a water/cement ratio as a no-slump concrete with an admixture.

    Standards Compliance
    SMF complies with the requirements of the following standards: ASTM C 494, Type F.
