STAR - 325
Description
STAR —325 is polymer engineered specifically towards the pre-cast pipe industry to produce the highest possible early age strength gain, with the lowest possible cement-water ratio.
STAR —325 has the effects of Steric and Electrostatic repulsion that helps in producing a product, which is more effective than conventional superplasticizer’s/water reducers.
STAR —325 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.
Area of Application
- Excellent dispersion resulting in High workability
- Increases early and ultimate strengths
- Concrete to be placed and compacted in congested reinforcements.
- Reduced labor requirements.
- Increases durability and impermeability
- Improve surface finish.
Advantages
- STAR —325 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 —325 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 —325 is chloride free, ideal for concrete containing embedded steel.
- STAR —325 is Anticorrosive in nature, neither initiates nor promotes corrosion.
- Allows workability to be increased without adding extra water.
Dosage
The optimum dosage determined by site trails with a specific concrete mix which enables the effects of workability, strength gain and setting time to be measured.
- The rate of addition of STAR —325 is typical between 0.5% to 1.5% of cement by weight.
- However, the dosage can be increased up to 2% with prior consultation with our technical service department.
