  • Who invented polycarboxylate superplasticizers in 2021?
  • 2021 marks the 40 th year since polycarboxylate superplasticizers (PCEs) have been invented by Nippon Shokubai company in Japan. This invention clearly represents a major breakthrough and milestone in modern concrete technology.
  • When were superplasticizers introduced?
  • Superplasticizers were introduced already in the 1930s. Since then the market has witnessed the appearance of different generations of products with improving performance. At the start of this chapter we provide an overview of the chemistry of these products. The last superplasticizer generation, polycarboxylates, brought the most radical changes.
  • Can superplasticizers be used in high-performance concrete?
  • The utilization of superplasticizers in the production of concrete offers several benefits such as improved workability, reduced water content, and increased strength. Nevertheless, the addition of superplasticizers in high-performance concrete may present challenges due to various factors.
  • Are PCE superplasticizers a breakthrough in modern concrete technology?
  • This invention clearly represents a major breakthrough and milestone in modern concrete technology. In this review article, at first Dr. Hirata – the main inventor of PCE superplasticizers – reports on the history behind their invention and market entry. Thereafter, recent developments and innovations in PCE technology are presented.
  • What are superplasticizers used for?
  • These materials can result in as high as 40% reduction in the water content. Thus, they are perfect in making high- and ultra-high-strength concrete with a water/cement ratio as low as 0.20. Usually, these superplasticizers show excellent retention of slump and do not delay the gain of concrete strength.
  • Are superplasticizers a problem in the construction industry?
  • The construction industry has a pressing need for the development of high-performance concrete. Notwithstanding their utility, the present superplasticizers encounter a number of obstacles, including but not limited to challenges in regulating the water–cement ratio, flowability, segregation, and expense.
