The invention discloses a concrete early strength agent, which is composed of the following components in parts by weight: 100 to 120 parts of potassium nitrate, 100 to 150 parts of white vitriol, 50 to 80 parts of sodium sulfide, 80 to 100 parts of potassium nitrate, 20 to 30 parts of gluconic acid, 15 to 20 parts of sodium lignosulfonate, 10 to 30 parts of active carbon, 30 to 50 parts of calcium oxide, 20 to 50 parts of titanium dioxide, 10 to 25 parts of coal cinder, 20 to 25 parts of high-alumina fly ash, and 30 to 35 parts of aluminum oxide. The concrete early strength agent has the characteristics of strong adaptability, low cost, and good early-strength effect, can replace an antifreeze agent in a temperature range of -5 to 5 DEG C, has the functions of promoting early strength, reducing water, preventing freezing, and enhancing the plasticity, does not contain any chlorine ion, does not corrode the steel bar, can be applied to silicate cement, and has a prominent enhancing and modifying effect on slag cement.
