(57) The invention discloses high-strength anti-crack concrete, and belongs to the technical field of building materials. The concrete is prepared from the following raw materials: cement, gravel, fine aggregate, water, anti-crack fibers, fly ash, a water reducing agent, an anti-freezing agent, redispersible latex powder, sodium carboxymethyl cellulose and an air entraining agent. According to the preparation method, firstly, basalt fibers are modified, and the adding mode and the adding proportion of anti-crack fibers are optimized, so that the optimization of the strength performance of the concrete is realized. The dispersible latex powder and other components are also added to play an auxiliary role in improving the strength of the concrete. The anti-freezing agent improves the anti-freezing performance of the concrete, and the air entraining agent reduces bubbles introduced by stirring and reduces the negative influence of the bubbles on the strength performance of the concrete. According to the raw material selection and preparation technology, the obtained concrete is excellent in comprehensive performance, high in strength, high in weather resistance, good in impermeability and low in cost.
