Guidelines for using superabsorbent polymers (SAP) in concrete construction

Abstract

Superabsorbent polymers (SAP) are highly promising chemical admixtures for concrete, offering numerous advantages in terms of water control within the mixture. These polymers present exciting possibilities for enhancing the rheological properties of fresh concrete and addressing challenges related to autogenous and plastic shrinkage through internal curing. An interesting characteristic of SAP is their ability to create stable pore systems regardless of the consistency of the concrete, the addition of superplasticizers, or the chosen method of placement and compaction. As a result, SAP emerges as a viable alternative to air‐entrainment agents. While the benefits of using SAP are evident, there is a lack of standards regulating their application by concrete producers. In this regard, the recommendations offered by RILEM may pave the path toward formal regulation. This article aims to provide an overview of these recommendations.
