FIELD: construction.
SUBSTANCE: invention relates to the industry of construction materials and can be used in making concrete mixtures. Device for production of concrete mixture additionally comprises device for pumped ice, connected to water bunker, having batcher and a distribution valve for feeding water into the mixing chamber of components or in a device for producing pumped ice, and connected by means of a pipeline to a mixing chamber of components.
EFFECT: due to gel-like, fine-dispersed state of pumped ice efficiency of mixing components of concrete mixture is increased, which does not lead to occurrence of defects of microstructure of concrete, which occur during freezing of liquid phase during hardening.
