The invention discloses anti-cracking concrete and belongs to the technical field of building materials. The anti-cracking concrete comprises, by weight, 300-600 parts of ordinary Portland cement, 200-400 parts of crushed stone, 100-300 parts of river sand, 6-10 parts of barite powder, 6-10 parts of sodium borate, 2-10 parts of phosphorous slag powder, 4-10 parts of silicon dioxide powder, 6-10 parts of cellulosic fiber, 4-12 parts of polypropylene fiber, and 350-450 parts of water. The anti-cracking concrete is capable of effectively preventing cracking of concrete structures caused by nonstructural factors, such as concrete temperature and concrete shrinkage, raw materials are rich and low in price, a production process is simple, the cost is low, and the anti-cracking concrete is suitable for large-scale production.
