摘　　要：回顾与总结了近十年来我国负温高强混凝土技术的研究状况与主要研究问题,涉及到负温高强混凝土的配合比设计、冻结模式、强度发展规律、抗冻临界强度、损伤过程、可靠度、防冻剂作用机理等问题,说明了我国冬期施工在这一领域中所取得的主要成果,并提出了供讨论用的负温高强混凝土今后的研究方向。Based on present situation and main subject for high strength concrete at minus-temperature in this ten years, it was investigated that the design of mix, freezing model, development rule of strength, resistant frost critical strength, damage process, reliability, anti-freezing agent action mechanism involve major matters of principle in winter construction concreting. And then, the field main result give brief reasons in high strength concrete at minus-temperature science and technology study. In the future subject and method, the viewpoint is discussing in high strength concrete at minus-temperature.
