Barrasuper Sodium Salt Of Sulfonated Naphthalene Formaldehyde Poly Condensate CAS 9084-06-4 Concrete Admixture
Barrasuper Sodium Salt Of Sulfonated Naphthalene Formaldehyde Poly Condensate CAS 9084-06-4 Concrete Admixture Product Description:
Naphthalene series superplasticizer (naphthalenesulfonic acid formaldehyde condensate) and some other chemical admixtures play an important role in modern concrete materials and technologies. It can improve the various properties of concrete and promote the development of new concrete technologies.
When used together with mineral admixtures (also known as mineral admixtures), it promotes the utilization of industrial by-products (such as ground slag and fly ash) in the cementitious material system, which helps to save resources and protect the environment. With the continuous search for more low-cost, environmentally compatible materials and technologies, it can be expected that naphthalene-based superplasticizers will play an important role in future concrete production.

Water reducing agent is also called plasticizer or dispersant. Adding an appropriate amount of water-reducing agent when mixing the concrete can make the cement particles evenly dispersed, and at the same time release the water wrapped by the cement particles, which can significantly reduce the water consumption of the concrete.
The function of the water reducing agent is to improve the workability of the concrete while keeping the mix ratio of the concrete unchanged; or to reduce the water consumption and increase the strength of the concrete while keeping the workability unchanged; or to reduce the amount of cement while keeping the strength unchanged. , Save cement and reduce costs.
At the same time, the concrete is more uniform and dense after adding water reducing agent, improving a series of physical and chemical properties, such as impermeability, frost resistance, erosion resistance, etc., and improving the durability of concrete.
In the past, water-reducing agents used in hydraulic concrete were generally ordinary water-reducing agents such as pulp waste liquid, wood calcium, and molasses.
The water-reducing rate was not high, generally 5%-10%. With the improvement of the quality requirements of hydraulic concrete, the quality requirements of the water reducing agent are also getting higher and higher. The naphthalene-based superplasticizers widely used in large hydropower projects such as Ertan and Three Gorges have a water reduction rate of up to 20% to 30%.
They are mainly used to prepare high-strength and high-fluid concrete or concrete that requires a significant reduction in water consumption. The superplasticizer has obvious effects on improving the efficiency of cement use, and can save about 20% of cement consumption.
