Concrete Admixture

Product Details:

• Conplast SP430 is a chloride free, superplasticising admixture based on selected sulphonated napthalene polymers. It is supplied as a brown solution which instantly disperses in water.
• Main Uses:
• To provide excellent acceleration of strength gain at early ages and major increases in strength at all ages by significantly reducing water demand in a concrete mix.
• Particularly suitable for precast concrete and other high early strength requirements.
• To significantly improve the workability of site mixed and precast concrete without increasing water demand.
• To provide improved durability by increasing ultimatestrengths and reducing concrete permeability.

• Major increases in strength at early ages without increased cement contents are of particular benefit in precast concrete, allowing earlier stripping times.
• Makes possible major reductions in water:cement ratio which allow the production of high strength concrete without excessive cement contents.
• Use in production of flowing concrete permits easier construction with quicker placing and compaction and reduced labour costs without increasing water content.
• Increased workability levels are maintained for longer than with ordinary sulphonated melamine admixtures.
• Improved cohesion and particle dispersion minimises segregation and bleeding and improves pumpability.
• Chloride free, safe for use in pre-stressed and reinforced concrete.
• In screed material, the lower water content leads to quicker drying times

Product Details:

• Conplast P211 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively and improving the consistency of the concrete.
• This produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased strengths to be taken.

• Allows specified strength grades to be met at reduced cement content or increased workability.
• Water reduction significantly improves compressive strengths at all ages and enhances durability through the production of low permeability concrete.
• Minimises the risk of segregation and bleeding and assists in the production of a dense, close textured surface, improving durability.
• Chloride free, safe for use in pre-stressed and reinforced concrete.

Product Details:

• Fosroc Auramix V200 is designed to meet the contradictory requirements of contemporary concrete where high fluidity, retention for longer periods of time in backdrop of varying concreting materials properties, lack of binder content and higher dosage requirements of HRWR may result in undesirable properties such as segregation, Fosroc Auramix V200 keeps mixes fluid, uniformed and placing friendly in these demanding requirements

• Reduces sensitivity to variations in moisture content in aggregates. Eliminate segregation and bleeding in mixes. Reduces pump pressure by decreasing plastic viscosity of concrete while keeping homogeneity and thereby reducing friction. Exhibits better passing-ability and pump-ability while keeps high fluid mixes homogeneous. No effect on setting time by Auramix V200, set time will be dictated by the HRWR or other admixtures used in mix. No effect on air entrainments. No effect on fluidity of mixes either in initial stage of the mix or in retention period. No adverse effect on early or later age strength. Exhibit better surface finish.
