  • 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.
  • 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.
  • 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.
  • What is superplasticizer compatibility?
  • The first moment consumption of Superplasticizer molecules after the mixing is qualified as the cement/Superplasticizer compatibility. It is very difficult to make high-performance concrete with a very low water-cement ratio, that it will still have a slump value of 50mm 30 minutes with an initial slump value of 200mm.
  • Why do we use specialized superplasticizers in RC?
  • However, the unique properties of RC, such as the high water demand and short setting time, necessitate the use of specialized superplasticizers that are different from those used in ordinary Portland cement. As an important component for the application of RC, superplasticizer has an important impact on the performance modification of RC.
  • 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.
