The invention discloses cement-based crack-resistant concrete. The cement-based crack-resistant concrete is prepared from the following raw materials in parts by weight: 80-100 parts of ordinary Portland cement, 45-50 parts of quartz sand, 20-25 parts of clay powder, 6-8 parts of a lentinu edodes cultivation material, 0.3-0.5 part of sodium lignosulphonate, 1.3-1.5 parts of waterborne polyurethane, 1.0-1.2 parts of acrylate, 8-10 parts of silicon oxide powder, 5-6 parts of boron oxide powder, 8-10 parts of distiller grains, 1.0-1.2 parts of a hydroxy carboxylic acid efficient water reducer, 3-4 parts of seaweed meal, 2-4 parts of peach tree bark and an appropriate amount of water. Since the concrete system is high in the content of solids, the pouring success rate of concrete can be ensured, the construction efficiency is increased and the construction cost is decreased; since clay, silicon oxide powder and boron oxide powder are added, the crack resistance of the concrete system is increased; and the lentinu edodes cultivation material is added so that the cement-based crack-resistant concrete has the advantages of quick drying, easiness in grinding, good adhesion force, environmental friendliness, no pollution and the like.
