摘　　要：过去在我国北方地区,绝大部分公路工程建设,由于初春和深秋季节气温转低而被迫停工,但近些年来,根据工程建设项目的实际要求和科学技术的进一步发展,越来越多的建设项目需要在低温季节施工。着重阐述了度时积对负温混凝土的影响。In the past, most highway construction project had to stop build because of lower temperature in the north of our country. But in the recent, more and more highway construction project need to construction at low temperature season due to the improvement of science and technology. The paper focus on studying the influence of temperature and time to negative temperature concrete.

关 键 词：度时积 负温混凝土 预养时间 混凝土强度
