Described is a cementitious material delivery system having at least one material box (10) with a lower access point (16) that is connected to a collection hopper (22). Also described is a cementitious material delivery system having at least one container (38) with an unloading end (42) that is located proximate to a collection hopper (22). The at least one container (38) can be positioned on at least one shelf (18) that can be raised so that the unloading end (42) is tilted toward the collection hopper (22).

A portable mixer includes a frame, a hopper for receiving therein dry cementitious mix, and a chute rigidly coupled to the hopper that communicates with the hopper via an aperture. The hopper and chute are pivotally coupled to the frame. The portable mixer further includes an auger extending from the hopper into the chute via the aperture, a water supply system configured to apply water to cementitious mix, and a motor coupled to the auger and configured to rotate the auger to mix the dry cementitious mix with the water.
