The invention relates to a construction method for winter masonry engineering. The construction method comprises the following steps that 1, dirt on the surfaces of masonry materials is removed, and bricks which are frozen due to water soaking are removed; 2, if lime putty is frozen, the lime putty is molten; 3, sand is evenly mixed to enable the sand to contain no frozen blocks and ice blocks with the diameter being larger than 10 mm; 4, the sand is preheated to be 20-35 DEG C, water is heated to be 40-70 DEG C, mortar is mixed under the environmental temperature being not lower than 5 DEG C,and the stirring time is prolonged by 0.5-1 time compared with the normal temperature condition; and 5, masonry construction is conducted, vertical mortar joints are filled before daily knocking off,mortar is not laid on the upper surfaces, and the masonry upper surfaces are covered with heat-preservation materials. Compared with the prior art, according to the construction method for winter masonry engineering, an anti-freezing agent and a modified micro-foaming agent of appropriate proportions are added into the mortar, the anti-freezing property, easiness and durability of the mortar areimproved, and the effective measures for guaranteeing of the masonry quality are provided in the construction process.
