STAR - 321
Description
STAR —321 is polymer engineered specifically towards the pre-cast concrete industry to produce the highest possible early age strength gain, with the lowest possible cementitious content.
STAR —321 has the effects of Steric and Electrostatic repulsion that helps in producing a product, which is more effective than conventional superplasticizers.
STAR —321 does not contain any added chloride ions ensuring that the product does not support corrosion of reinforcing steel. Being anti corrosive in nature, helps concrete and steel to prevent corrosion.
STAR —325 is a new generation polymeric superplasticizer/high range water reducer based on polycarboxylate Ether technology
Area of Application
- To produce high early strength concrete
- Self-compactable concrete
- Water reduction up to 40%.
- Ready Mix and Pre-cast Concrete Industries where high durability and performance is required.
Advantages
- STAR —321 provide early age compressive strength developments that improve productivity, earlier transfer of pre-stress and negate the need for accelerating admixtures during cold temperature working.
- STAR —321 provides better consistency, requires little or no vibration in highly workable concretes.
- STAR —321 reduce surface cohesion makes concrete floating and finishing requires less labour involvement.
- STAR —321 improves rheology of concrete provides a blemish free surface finish, requiring less repair work.
- STAR —321 is chloride free, ideal for concrete containing embedded steel.
- STAR —321 is Anticorrosive in nature, neither initiates nor promotes corrosion.
- Allows workability to be increased without adding extra water.
Dosage
Reduction to be measured. Site trial with this product should always be compared with mix containing no admixture. is dosed between 0.3% and 1.5% of cement by weight. However, the dosage can be increased up to 2% with prior consultation with our technical service department.
