The concrete admixtures are also called concrete additives. These materials are added to the concrete before mixing or during the mixing process to improve the properties of the fresh concrete. The dosage of concrete additive is generally not more than 5% of the cement dosage. The characteristics of concrete additives are characterized by many varieties and small amounts, which have a great influence on the performance of concrete. In addition, it has the characteristics of less investment, quick effect, and remarkable technical and economic benefits. Reasonable use of admixtures in concrete can achieve various technical-economic benefits such as saving cement, saving energy, shortening the construction period, improving concrete properties, and construction operating conditions.
There are four types of concrete additives in Kingsun. And they are sodium gluconate, sodium lignosulfonate, sodium naphthalene sulfonate, and polycarboxylate superplasticizer. Although these products are water reducer, they have some differences. Here is some information about the four products.
1. Sodium Gluconate
Sodium gluconate has a good water-reducing effect and retarding retardation in the concrete industry. Besides, it can also enhance the plasticity, fastness, and strength of concrete.
2. Sodium Lignosulfonate
As a surfactant, Kingsun sodium lignosulfonate is widely used. For example, sodium lignin sulfonate is a concrete water reducer, coal water slurry additive, refractory, and ceramic body reinforcement. Moreover, it can also act as fillers and dispersants for the dye industry and pesticide processing, binder for powdered and granulated materials, dilution dispersant, and viscosity reducer in drilling.
The naphthalene-based high-efficiency water reducing agent has strong adaptability to cement. It is especially suitable for fluid concrete with high water reduction and enhanced requirements, steamed concrete, and it can also be used as a matrix material for composite admixtures. The main performance characteristics of sodium naphthalene sulfonate are as follows:
Polycarboxylate superplasticizer is a high-performance water reducing agent. Widely used in highways, bridges, dams, tunnels, high-rise buildings, and other projects. It is also suitable for projects with long construction time and high requirements for concrete slumps, such as nuclear power engineering. The product is environmentally friendly, non-flammable, non-explosive, moreover, it can be safely transported by train and car. It has many advantages, such as low dosage, high water reduction rate, small slump loss, good workability and stability of concrete, etc.
The use of admixtures directly affects the performance of concrete, so a suitable admixture should be selected before construction. According to the need to choose the most suitable admixture, it can maximize the advantages of concrete. As a leading concrete admixtures manufacturer and supplier in China, KINGSUN has always focused on providing the most suitable and highest quality products according to customer’s needs. Our products have exported to around 60 countries and regions, such as India, South Korea, Vietnam, Indonesia, Pakistan, Brazil, South Africa, Chile, Australia, Russia, Ukraine, etc. If you want to know more details about Kingsun concrete chemicals or what is a suitable admixture for you, please leave us a message or send an e-mail, we will be happy to help you.
