FIELD: process engineering.
SUBSTANCE: invention relates to construction and can be used for high-quality processing of uncured reinforced concrete surfaces of articles moulded from concrete mixes for civil and industrial construction. Concrete surface finisher working disc tool consists of body, motor, drive shaft and smoothing disc. Besides, it comprises cathode immersed in concrete mix and rheostat to control electric field gradient and to transmit electricity via current collector to drive shaft and smoothing disc. Note here that is it possible to influence processed concrete surface by electric effects.
EFFECT: higher surface quality and hardness.
