Duplast SP

High-range, Water Reducing Super plasticizer for High Performance Concrete Mixes
Dubond's Duplast SP (Super Plasticizer) is composed of synthetic polymers specially designed to allow considerable reduction of mixing water while maintaining control on extend of set retardation. It is a prefen-ed admixture for triple blend binder system based High Performance Concrete (HPC) mixes or mixes containing micro silica or metakaolin.

Better compaction and finishing by acting as viscosity modifier
Breaks the salinity of water by converting them into salt crystals
Chloride free
Extended setting with longer work ability
Good dispersion even in mixes with high fines
High work ability for longer periods
Higher cohesion
Higher ultimate strengths
Increased ease in finishing concrete
Increases extra bonding strength
Lower pumping pressure
Lowers cement content for increase in specified strength, work ability & durability
Reduce risk of honeycombing
Reduce risk of shrinkage cracks due to heat of hydration
Reduced permeability
Reduced thermal peaks
Reduced water content for a given work ability
Reduces the risk of rusting of reinforcement by breaking the chain of rust electrons
Resistance to segregation and bleeding even at high work ability

Concrete containing Silica fume/ Metakaolin
Congested/complex reinforced sections
Long-distance transporting
Low water/binder ratio mixes
Mixes requiring > 20% water reductions
Pre-cast concrete production
Pumped concrete
Ready mixed concrete

Duplast SP is a ready-to-use liquid which is dispensed into the concrete together with the mixing water. The plasticising effect and water reduction are higher if the admixture is added to the damp concrete after 50% to 70% of the mixing water has been added.

As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapour until product fully cured or dried).
