Polycarboxylate high-performance water reducer-Polycarboxylate superplasticizer Introduction: Based on polycarboxylic copolymer and polyhydroxy, Point-400S is a low and medium concentration polycarboxylic superplasticizer special for low and medium strength level concrete. It is compounded by various high efficiency functionalization agents with optimized compound technology. Compared to the naphthalene superplasticizer of the most consumption at current market and its derivative products, Point-400S has better workability, better slump retaining performance and smaller concrete shrinkage, and it can effectively reduce hydration heat in initial stage, control temperature cracking and enhance concrete compressive strength. It is the ideal substitute products for admixtures such as superplasticizer of naphthalene series, aliphatic series and sulfamic acid series, and pumping agent. Point-400S has the comprehensive performance advantages of polycarboxylate superplasticizer. Besides improving the workability of fresh concrete, it can effectively reduce the shrinkage of hardened concrete, enhance the volume stability and durability of concrete structures, and effectively realize the high performance of low-level ordinary commercial concrete. Point-400S was awarded as second prize of Year 2011 Xiamen excellent new product award and second prize of Year 2012 Fujian science and technology award. | -15424551564.jpg) |
Features: Excellent workability: It can effectively improve the plasticizing and cohesiveness of concrete, and especially that it can effectively avoid bleeding and separation, significantly improve the workability of fresh concrete and enhance concrete pumping performance. Providing effective measures for controlling cracking: When applied with mixtures like fly ash and grinded slag, it can effectively prevent and control the occurrence of temperature cracking for large volume concrete; meanwhile, it has low shrinkage percentage and can effectively prevent the occurrence of shrinkage cracking, thus to improve engineering quality. Realizing high performance of ordinary commercial concrete: It can effectively improve the pore structure of concrete and significantly enhance the durability indexes such as anti- carbonation, dry-wet cycle and freeze-thaw cycle, thus to realize the high performance of ordinary concrete to some extent. No crystallization in winter: Due to low concentration and low content of sodium sulfate, it has no crystallization in winter, which greatly solve the crystallization issue of naphthalene series product in winter. Safety property: Non-toxic, non-irritant, non-radioactive, nonflammable, non-explosive, non-dangerous, and no corrosive to steel bar. |
