Superplastyfikator BG97 40

Superplastyfikator BG97 40 is a water solution of sodium salt of polycondensate of naphthalenesulfonic acids with formaldehyde (NSF) characterized by properties necessary for the production of concrete with very good workability and strength. It is highly effective as a concrete mix plasticizer, improving its workability while maintaining a constant water to cement ratio and at the same time not impairing the compressive strength of hardened concrete. This saves labor costs when pumping out the mix. However, the main component affecting the price of concrete is cement, the amount of which in the recipe can be reduced by using Superplasticizer BG97 40 . This admixture allows you to reduce the amount of mixing water used by up to 25%, while reducing cement consumption (while maintaining a constant water-cement ratio). It shows a similar property when mixed with gypsum during the production of drywall. Another important aspect in the production of concrete is the preservation of the workability of the concrete mix over time. Thanks to the properties that delay cement setting, which are the characteristics of the superplasticizer, it is possible to extend the workability, and therefore also to transport the concrete mix over longer distances, even in the summer. The essence of a concrete structure is its durability and strength, which are improved when we use an admixture. The research shows that hardened concrete with the admixture of Superplasticizer BG97 40 has a compressive strength up to 30% higher compared to concrete without the admixture. Thanks to the very low concentration of chlorides, the product does not contribute to the corrosion of steel reinforcements in concrete structures. In addition, it allows you to make a concrete mix at an air temperature of up to -5°C without inhibiting cement hydration.
The use of Superplasticizer BG97 40 allows for the production of cheap and environmentally friendly concrete, which at the same time is characterized by very good strength and rheological properties. It is mainly recommended for the production of ready-mixed concrete.
