The invention discloses a high-cracking-resistance concrete curing agent. The concrete curing agent is made of, by weight, 20 parts to 45 parts of sodium silicate, 15 parts to 35 parts of heavy calcium carbonate, 10 parts to 25 parts of aluminum silicate and 25 parts to 55 parts of polypropylene fibers. By means of the concrete curing agent, the polypropylene fibers are added in the concrete curing agent, and accordingly, microcracks caused by factors of concrete solid plastic shrinkage, air shrinkage, temperature variation and the like can be controlled effectively, forming and developing of cracks can be prevented and restrained, the crack-resistant anti-penetrability performance and the shock resistance and aseismic capacity are improved greatly, cracks of concrete can be reduced effectively, and the concrete curing agent is particularly applicable to construction projects of houses, roads, bridges and the like.
