A REVIEW OF SHRINKAGE AND CRACK RESISTANCE OF INTERNAL CURED CONCRETE USING SAP AS AN INTERNAL CURING AGENT
Main article
Abstract
Concrete is the most widely used construction material globally, but its production requires substantial amounts of water for casting and curing. With water scarcity becoming a pressing concern, alternative methods to reduce water consumption while maintaining or enhancing concrete properties are vital. Internal curing using superabsorbent polymers (SAPs) has emerged as a promising solution to address this challenge. This paper explores the mechanisms, benefits, and applications of internal curing concrete, with a particular focus on the role of SAPs. SAPs function by
absorbing and retaining water, which is gradually released during the hydration process. This mechanism helps mitigate autogenous shrinkage, a common cause of cracking in concrete, thereby improving the material’s crack resistance and overall durability. The review highlights the advantages of SAPs in enhancing the performance and sustainability of concrete, positioning them as a viable alternative to traditional curing methods. However, it also underscores the need for further research to optimize the use of SAPs and validate their long-term benefits across
various construction applications. By providing insights into the potential of internal curing with SAPs, this study contributes to the ongoing efforts to develop more sustainable and durable concrete solutions. Future studies should focus on refining the application of SAPs and exploring their effectiveness in diverse environmental and structural conditions.
