A composition for improving the durability of concrete, including single 10 ~ 50, 0 ~ 26 neutralizing agent and reducing agent 0.01 - 0.50, 0.01 - 0.20, crosslinking agent modification agent 1 ~ 10, 0.05 ~ 0.30 oxidant and water 20 to 90 weight parts of raw materials. The invention adopts mixing in the construction field to spray or impregnate the micro crack, micro gap and the body of the concrete, and synthesize the superabsorbent resin in situ by far infrared radiation. The water absorption, swelling, dense cracks or pores of the in-situ synthesized water absorbent resin are used to cut off the transmission path of the medium water, so as to improve the durability of the concrete. After testing, the composition of the invention of concrete specimen, the impermeability pressure increases from 70% to 180%, the frost resistance of concrete is increased by 15% ~ 35%, the strength loss rate decreased by 57% ~ 84%, 56% ~ 86% mass loss decreased after corrosion of sulphate and chloride ion penetration resistance increased 1.7 ~ 8.50 times, the anti carbonation performance is improved 50%.
