A portable concrete mixer includes a frame, a hopper, coupled to the frame, for receiving therein dry commercially available prepackaged concrete mixes containing gravel aggregates, a chute coupled to the hopper, a water supply system that supplies water to the chute, a motor, and an auger coupled to and rotated by the motor. The auger includes a shaftless helical auger body extending from the hopper into the chute via an aperture in the hopper. The shaftless helical auger body has an interior volume and a plurality of fingers extending from the auger body into the interior volume. The shaftless helical auger body has an uneven pitch such that a second portion of the helical auger body in the chute has a greater pitch than a first portion of the helical auger body in the hopper.
