The invention relates to anti-freezing and anti-cracking concrete in the field of building materials. The anti-freezing and anti-cracking concrete comprises following components in percentage by weight, 10-20% of cement, 25-30% of sand, 30-45% of gravel, 10-15% of water, 2.0-5.0% of additives, 1.0-2.0% of water-proof agent and 0.0-1.4% of anti-freezing agent, and is produced by burdening and stirring. Compared with the prior art, the anti-freezing and anti-cracking concrete has the advantages of high strength, good toughness, cracking resistance, leakage resistance, high stability and the like, is capable of effectively solving the problems of cracking, brittleness and water seepage caused by the fact that the concrete is subjected to repeated freezing and thawing due to change of temperature difference, and increasing the indexes such as strength, toughness and stability, and is especially suitable for high and cold areas in north.
