FIELD: process engineering.

SUBSTANCE: invention relates to production of mortars. Proposed concrete mixer comprises drive drum and independent working rolling rods. The latter is composed of at least one strip bent in straight lines arranged at the angle to strip edges to make identical parallelograms alternating in opposite directions. Said perforated strip is coiled in helical turns interconnected in lengthwise edges to make unidirectional broken helical lines and identical broken perforated triangular pockets over drum inner and outer surface.
