BC 104NPC.n is a concrete superplasticizer based on naphthalene sulfonate polymers that is capable of significantly reducing mixing water and significantly increasing the strength of concrete, especially over long periods of time.
Description
The product BC 104NPC.n is a concrete superplasticizer based on naphthalene sulfonate polymers that can significantly reduce the mixing water and significantly increase the strength of concrete, especially at long ages.
This material disperses the fine particles in the concrete mix and makes the water in the mix act more effectively.
104NPC enables the production of fluid concrete with a very low water-to-cement ratio. Concrete containing 104NPC has higher strength than concrete without the additive and with the same performance. The obvious increase in strength remains at later ages, whether in air or steam curing. Initial and final setting occurs slightly earlier compared to concrete without the additive.
This strength development feature allows for energy savings in steam curing in precast factories.
Applications
Ready-mix concrete industries
Precast concrete
In designs where the water-to-cement ratio is very low, it is possible to produce concrete with very high long-term strengths.
High-density and impermeable concrete
Production of strong concrete
High density of reinforcement
Increase in durability of hardened concrete
Prestressed concrete
Features and benefits
Reduce cement grade
Increase in slump or concrete efficiency
Increase in concrete workability time
Ease of pumping and reduce equipment depreciation
Reduce water to cement ratio by about 12% to 20%
Increase in concrete compressive strength
Reduce concrete permeability
Compatibility with various types of Portland cement
Prevent concrete creep and shrinkage
Improve adhesion to reinforcement and steel
How to use
The consumption rate is between 0.5 and 1% by weight of the cement used (half a percent to one percent for 100 kg of cement), and the definitive consumption rate should be obtained by workshop tests, depending on different weather conditions and the type of sand, gravel, and cement used.
Superplasticizer 104NPC.n is a ready-to-use admixture and should be added at the time of concrete preparation. It is most effective when about 50 to 70 percent of the concrete water is added. Never add this product to dry materials. Stir the mixture for 60 seconds with a high-speed paddle to mix thoroughly.
