Polycarboxylate Superplasticizer Powder Slump Retention HS 382440100

In many concrete projects, traditional high-efficiency concretes such as naphthalene series are increasingly unable to meet the needs of the project due to the limitations of technical performance. A new generation of water-reducing agent that has attracted much attention at home and abroad, polycarboxylic acid-based high-performance water-reducing agent, because it has truly designed an effective molecular structure based on the mechanism of dispersed cement, it has a super-dispersed type and can prevent concrete slump loss Without causing obvious retardation, it can exert a higher plasticizing effect at low content, good fluidity retention, a large degree of freedom for the cement to adapt to a wide range of molecular structures, multiple synthesis technologies, and a large room for high performance, which can enhance concrete The effect is remarkable, it can reduce the shrinkage of concrete, the content of harmful substances is very low, and other technical performance characteristics, which endow the concrete with excellent construction and workability, good strength development, excellent durability, and polycarboxylate high-performance water-reducing agent Comprehensive technical performance advantages and environmental protection characteristics meet the needs of modern concrete engineering. Therefore, polycarboxylic acid-based high-performance water-reducing agents are gradually becoming the first-choice admixture for the preparation of high-performance concrete.
