The invention belongs to the technical field of concrete construction, and particularly relates to a cold region cold weather concrete construction method. The method comprises the following steps of 1, selecting raw materials, and preparing cement, aggregate, water and an additive for use; 2, preparing tools and equipment for construction; 3, according to actual situation, adopting a matching ratio adjusting method, a heat storage and thermal insulation method, an external heating method or an additive mixing method for concrete raw material mixing; 4, constructing the heat preservation environment in the mixed concrete conveying process; 5, performing concrete pouring operation; 6, performing concrete maintenance. The method has the advantages that due to the fact that some characteristics of concrete are changed or poured concrete is subjected to external insulation measures, a traditional technology for spraying chloride on the surface of poured concrete for heat insulation is replaced, normal construction can be kept on the condition that the temperature is quite low, and the construction progress speed is increased on the premise that the quality is ensured.
