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).

Cellular concrete is formed from a cement-based wet mix slurry with a foam entrained into the wet mix. The foam is created using a foaming agent, mixed with water and air using a foam generator. The wet mix is mixed with the foam to form the cellular concrete wet mix. Poor component metering and blending practices in the current state of the art limits the performance capabilities of existing cellular concrete placements. The presently disclosed technology addresses this with a cellular concrete mixing system comprising a dry mix hopper to store a quantity of dry mix, a mixing tank to blend the dry mix and water together to form a wet mix, a holding tank to store a quantity of the wet mix, a foam generator to generate foam from air, water, and foam concentrate, and a blend controller to control operation of the overall mixing system.
