The invention discloses novel anti-cracking concrete, and belongs to the technical field of construction materials. The anti-cracking concrete is prepared from the following raw materials in parts by weight: 300-600 parts of cement, 200-500 parts of aggregates, 200-500 parts of river sands, 2-10 parts of pulverized fuel ash, 1-9 parts of sodium sulfite powder, 2-10 parts of phosphorous slag powder, 4-10 parts of silica powder, 4-16 parts of polypropylene fibers and 350-450 parts of water. The novel anti-cracking concrete can be used for effectively preventing a concrete structure cracking caused by concrete temperature, air shrinkage and other non-structural reasons, has the advantages of rich raw materials, low price, simple production process and low cost, and is suitable for large-scale production.
