PURPOSE: A concrete curing apparatus by using ultrasonic waves is provided to improve the strength and the quality by bonding cement, gravel and sand efficiently with activating moisture in generating ultrasonic waves to a mold form. CONSTITUTION: Plural ultrasonic generators(2) are mounted to the side of a mold form(1) for forming cement or concrete products, and connected to a control unit(4) by a cable(3). Concrete is mixed with cement, gravel, sand and water, and poured into the mold form for forming drain pipes or poles. The control unit regulates power in forming concrete in the mold form, and sets the intensity of ultrasonic wave of the ultrasonic generator corresponding to the thickness of the product. Bonding force between steel concrete, cement, gravel, sand and water is increased by activating water with projecting the ultrasonic wave into the mold form, and the solidified structure is formed by filling the pores with cement or sand with fine vibration.
