相变混凝土抗冻性研究现状及发展方向
Research Status and Development Trend of Frost Resistance of Phase Change Concrete
摘要
Abstract
The frost resistance of concrete in cold regions is a key indicator for evaluating the durability of concrete.The ice swelling stress and static water stress caused by the positive and negative temperature cycles in the external environment and changes in concrete saturation will cause internal and external cracks in the concrete structure,reduce the strength and stiffness of the concrete,damage the overall integrity,stability and durability of the structure,and even induce penetrating cracks until failure.The use of phase change materials to release latent heat compensation during the phase change process to alleviate the freezing of internal pore water in concrete,thereby improving the frost resistance of concrete in cold regions,will be of great significance for extending the service life of concrete structures.This article summarizes and analyzes the research progress on using phase change materials to improve the frost resistance of concrete at home and abroad,and proposes the urgent problems in current research and the future research directions of phase change concrete.关键词
