The invention relates to an organic composite reinforced concrete corrosion resistant agent, which comprises the following components in part by weight: 60-200 corrosion resistant component, 20-30 water reducer active constituent, 5-15 delayed coagulation component sodium gluconate, 0.2-1 bleed air component alkyl sodium sulfonate and 330-580 water. The invention can be applied to the severe environment with high chloride ion concentration, alternation of wetting and drying, severe cold and the like. The invention has no negative influence on the performance of concrete and has good corrosion resistant effect, and has the functions of reducing water, delaying condensation and bleed air.
