A critical review on drying shrinkage mitigation strategies in cement-based materials

Abstract

Drying shrinkage deformation due to moisture migration is a major concern in cementitious materials and can lead to a high probability of cracking, resulting in a deterioration in long-term performance and serviceability. In this paper, the primary mechanisms of drying shrinkage, mitigation strategies and the research gaps are elucidated to provide a comprehensive understanding of the factors influencing drying shrinkage and identify research strategies to assist in the development of novel shrinkage-resistant concrete. The use of shrinkage-reducing admixture is identified as the high-efficiency methodology. This reduces the surface tension of the liquid in the capillary pore, resulting in a..
