The invention relates to a preparation method of lightweight aggregate concrete. A machine for preparing the lightweight aggregate concrete is used. The machine comprises a base, L-shaped fixing plates, a crushing device and a screening device, wherein the L-shaped fixing plates are symmetrically fixed on the left side and the right side of the middle of the upper end surface of the base, the crushing device is connected between the upper ends of the L-shaped fixing plates, the screening device is arranged below the crushing device, and the screening device is arranged on the L-shaped fixing plates. According to the preparation method, the problems that when traditional lightweight aggregate concrete is prepared, common fly ash particles are large and contain part of impurities, so that the setting time of the concrete is prolonged, and the strength of the lightweight aggregate concrete is reduced, and when one of the raw materials, namely fly ash, of the lightweight aggregate concrete is prepared, more fly a
