The Impact of Super Absorbent Polymers on Concrete Strength
Keywords:
Concrete Strength, Curing, Gel, Super Absorbent PolymerAbstract
SAP (Super Absorbent Polymer), one of the advanced materials, offers significant promise in the field of civil engineering. SAP may affect concrete in a number of ways, including cracking, shrinkage, tensile strength, and compressive strength. We'll examine at how SAP influences concrete strength in this study, but we'll also look at other aspects. Sodium Polyacrylate will be the focus of our investigation. The fundamental function of SAP is to serve as an internal water supply, also known as an internal curing agent, which is critical during the post final setting stage of cement. Furthermore, as it weakens concrete by creating a gel with water, SAP introduces some extra voids. SAP, or Super Absorbent Polymer, is a smart material with high absorbency. In addition to replacing super plasticizers, it also serves as a plasticizer in its own right. In this investigation, we will focus on the influence of SAP on both freshly-poured concrete and concrete that has already been hardened in order to determine the strength of concrete over different loading conditions.
