The invention relates to an anti-freezing concrete using a steam-curing technology. The anti-freezing concrete is characterized in that a freezing and thawing-resistant concrete is prepared from the following components in parts by weight: 10 to 13 parts of cement, 29 to 32 parts of fine aggregate, 43 to 48 parts of coarse aggregate, 4 to 5 parts of ore slag powder, 0 to 0.5 part of silicon ash, 0 to 4 parts of fly ash, 0.2 to 0.4 part of water reducer, 0 to 0.1 part of air entraining agent, and 4.8 to 6 parts of water. The anti-freezing concrete prepared by the formula has the beneficial effects that the speed of finished products of the concrete prefabricated part is accelerated; the freezing and thawing-resistant property can reach F350 or above; the production of a large batch of defective products is avoided; the freezing and thawing-resistant property is higher, the production cost is low, and the strength can meet the engineering requirements. 本发明涉及种采用蒸养工艺的抗冻混凝土，其特征是：按重量份数制成的抗冻融性混凝土组分为，水泥10～13、细骨料29～32
