摘要

Curing is a critical procedure in concrete technology that ensures concrete retains adequate moisture and temperature over a specific period, allowing it to develop its intended physical and mechanical characteristics. Proper curing is vital for developing the required strength, durability, and internal structure, all of which ensure the long-term reliability of concrete constructions. This review systematically examines the effects of various curing conditions on key parameters such as mechanical behavior, durability indicators, and microstructural characteristics. A range of methods is assessed, including standard water curing, curing compounds (acrylic-based, composite-based, silicate-based, and paraffin-based), steam curing, and other alternative techniques. The findings demonstrate that standard water curing consistently produces superior compressive strengths compared to other methods. Acrylic-based and composite-based compounds also contribute to notable strength and durability enhancements, while silicate-based and paraffin-based formulations are associated with reduced mechanical performance, highlighting the importance of sustained moisture retention. Steam curing is shown to be particularly effective, achieving high early-age strengths and enhancing performance in specialized concrete applications such as precast elements. Microstructural evaluations reveal that effective curing reduces porosity, improves matrix densification, and lowers permeability, contributing to longer service life and improved durability. Overall, the review emphasizes the necessity of adopting optimized, project-specific curing practices to ensure the structural reliability, durability, and sustainability of concrete under varying environmental and operational conditions.
