Superplasticizer - an overview | ScienceDirect Topics
Superplasticizers are a fundamental ingredient for lowering the yield stress of concrete. This chapter provides an overview of the chemical classes of superplasticizers and their performance, with a selective review of those aspects that we consider important in understanding superplasticizers. We also demonstrate the consistency in findings
Use of Water Reducers, Retarders, and Superplasticizer
There are four types of superplasticizers: sulfonated melamine, sulfonated naphthalene, modified lignosulfonates and a combination of high dosages of water reducing and accelerating admixtures. Commonly used are melamine based and naphthalene based superplasticizers.
Sodium Naphthalene Sulfonate Formaldehyde (SNF/PNS/NSF/FND)
As one of the most professional concrete admixtures manufacturers & suppliers in China, . has focused on researching and producing various types of water reducing admixtures for more than 15 years.
Concrete Superplasticizer - High Range Water Reducer in Kingsun
The superplasticizer for concrete has the functions of high-efficiency water reduction, retardation, slump retention and reinforcement. This product has strong adaptability to cement, less dosage, and is easy to use. It is especially suitable for concrete projects that require high-efficiency water reduction and retardation.
Concrete Water Reducer - Superplasticizers
7. Since the dosage of polycarboxylic acid superplasticizer is very small, the water reduction rate is high. The use of polycarboxylic acid superplasticizers to prepare various types of high-performance concretes above C45 can greatly reduce project costs and has significant technical and economic benefits; it is used to prepare concrete below C45, although the cost of polycarboxylic acid
