The microstructure and durability of concrete are greatly influenced by the curing temperature. High‐temperature curing accelerates cement hydration; however, it may lead to uneven distribution of hydration products and increased porosity. In contrast, low‐temperature curing retards hydration, resulting in an insufficient hydration formation products and a corresponding increase in porosity. Under negative‐temperature conditions, hydration is further inhibited, while pore water freezes and expands, generating internal stresses that promote the development of pores and microcracks. Consequently, these effects increase the proportion of harmful pores in concrete and enhance its permeability, thereby facilitating the ingress of aggressive substances and ultimately compromising durability. This paper systematically analyzes and summarizes the research on the microstructure and durability of concrete caused by curing temperature and forecasts and examines the trends and directions of its upcoming research.
