The invention discloses an ultralow temperature concrete antifreeze agent and an application thereof. The antifreeze agent comprises, by mass, 10-20 parts of calcium silicate hydrate, 4-8 parts of rubber powder, 3.5-8.7 parts of sodium nitrite, 2.8-6.5 parts of sodium sulfate, 2-5 parts of organic alcohol amine, 0.1-0.7 parts of triterpenoid saponin, 2.35-5.48 parts of thioglycolic acid, 6.4-10.5 parts of acrylamide, 1.0-1.8 parts of sodium dodecanesulphonate, 2-4 parts of melamine and 8-10 parts of sodium gluconate. The antifreeze agent can adapt to environment with a lowest temperature of -50DEG C, the dosage of the antifreeze agent in concrete is 20% of the mass of cement in concrete, the -7+28d strength of concrete can reach standard curing 28d concrete strength, and product performances can reach GB475 standard requirements.
