The invention discloses a preparation method of a cold resistant concrete brick. The method includes the following steps: a, blending cement, sandstone, fly ash and water according to proportion, stirring and smashing the mixture in a mixer, and stirring for 10 minutes; b, adding broken sand, a water reducing agent, superfine slag powder and an anti-freezer agent into the mixer, and stirring for 30 min to form an absorption layer mixture; c, taking out the absorption layer mixture with a shovel, putting the mixture into a brick machine and pressing a concrete brick; and d, curing the moulded concrete brick in a curing room for 1-3 days to prepare the cold resistant concrete brick. The preparation method of the cold resistant concrete brick provided by the invention is simple for operation; the cold resistant concrete brick is applicable to construction in cold weather in winter, and the water can not be easily and rapidly evaporated; the added slag powder and anti-freezer enable the prepared concrete brick with good cold resistance, and no easy cracking property.
