Production method of high-crack-resistance concrete

The invention discloses a production method of high-crack-resistance concrete. The concrete is prepared from cement, water, aggregate, sand, fiber and additives, Portland cement is adopted as the cement, stone with irregular shapes is adopted as the coarse aggregate, river sand is adopted as the fine aggregate, polypropylene fiber is adopted as the fiber, and a retarder and a thickener are adopted as the additives; the cement is Portland cement, the use amount of the cement is 20-25% of the total mass of the concrete, the coarse aggregate is 10-20 mm broken stones, the use amount of the coarse aggregate is 20-30% of the total mass of the concrete, the sand is spun yarns, the use amount of the sand is 40-50% of the total mass of the concrete, the water is underground water, and the use amount of the water is 20-25% of the total mass of the concrete. The fibers are polypropylene fibers, the use amount of the fibers is 0.5%-1% of the total mass of the concrete, and the use amount of the additive is 0.5%-0.8% of
