Conplast SP430 is a high range superplasticising admixture.Complies with IS:9103:1999 and BS:5075 part 3. It also conforms to ASTM C-494 Type ‘F’ and type ‘G’, depending on the dosages usedAquaproof Anchoring Systems is authorised project Super stockist and brushbond authorised Fosroc applicator for Fosroc Chemicals(India) in Pune, Maharashtra and a leading dealer for construction chemicals.

Advantages:

• 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 prestressed and reinforced concrete.

Speeds up construction, increses workablity and cohesion. Aids pumping by reducing line friction and dry packing. Low porosity resulting in substantially improved water penetration resistance.

The optimum dosage is best determined by site trials with the concrete mix which enables the effects of workability, strength gain or cement reduction to be measured. Site trials with Conplast SP430 should always be compared with mix containing no admixture. As a guide, the rate of addition is generally in the range of 0.5 – 2.0 litres /100 kg cement.

Conplast SP430 is supplied in 5,20 and 200 litre drums.
