PURPOSE: A cement reducing agent and high strength curing method using the same are provided to minimize use amount of cement and prevent strength degradation. CONSTITUTION: A cement reducing agent comprises 10-15 parts by weight of KCL, 5-10 parts by weight of sodium chloride, 5-10 parts by weight of ammonium chloride, 1-5 parts by weight of nickel chloride, 1-5 parts by weight of cobalt chloride, 20-30 parts by weight of sodium carbonate, and 5-15 parts by weight of potassium carbonate. A high strength curing method of construction comprises the following steps: manufacturing cement reducing agent(s10); manufacturing a mixture by mixing 100 parts by weight of aggregate and 1-10 parts by weight of the cement reducing agent(s20); dry-mixing after putting 16-25 parts by weight of water into the mixture(s30); and installing and curing the mixture(s40).
