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.
Who invented PCE superplasticizers?
In this article, at first Dr. Tsuyoshi Hirata - the main inventor of PCE superplasticizers – reports on the history behind the invention of PCEs. Next, a critical overview of recent innovations in PCE technology with an emphasis on novel polycarboxylate chemistries is presented.
What challenges did superplasticizers face?
However, they introduced new challenges, such as significant slump, high production costs, and environmental pollution [15,16]. In a pivotal development in 1986, Nippon Shokubai Corporation pioneered the creation of polycarboxylate (PCE) superplasticizers, marking the advent of the third generation of high-efficiency superplasticizers .
What are PCE-based superplasticizers?
The development of superplasticizers is one of the most important breakthroughs that have led to the production of high-performance concrete. PCE-based superplasticizers are the latest generations of superplasticizers, the addition of which to cement paste provides self-compacting concrete with a very low W/C ratio.
When were superplasticizers invented?
In the 1960s, the first generation of synthetic superplasticizers was introduced. These were based on sulfonated melamine-formaldehyde resins and sulfonated naphthalene-formaldehyde condensate and allowed improved workability and could reduce water content.
Are advanced superplasticizers based on polycarboxylate polymers?
Advanced superplasticizers, which are based on the family of polycarboxylate polymers (PCEs), have been proposed in the past decade [11, 12, 13, 14].
