The invention provides compositions and methods directed to carbonation of a cement mix during mixing. The carbonation may be in a stationary mixer or a transportable mixer, such as a drum of a ready-mix truck.

A concrete mixer vehicle comprises a chassis, an engine, a cab, a drum assembly, a front roller pedestal, a transmission mounting bracket assembly, and a rear pedestal. The chassis has a frame. The drum assembly includes a mixing drum, a drum driver, and a hopper assembly. The front roller pedestal is configured to support a front end of the mixing drum. The front roller pedestal includes a support member configured to provide support to the front roller pedestal in a longitudinal direction with respect to a longitudinal axis of the frame. The rear pedestal is configured to support a rear end of the mixing drum. The rear pedestal includes a first bar-pin member and a second bar-pin member configured to couple the rear pedestal in a first installation position or a second installation position based on a length of the mixing drum.

A concrete mixer including a mixing tub having an annular side wall and a bottom wall, a main frame configured to rotatably support the mixing tub, where the main frame includes a telescoping member that is capable of extending between a first length and a second length, and a base frame supporting the main frame. The base frame includes a first leg having a first wheel to enable transport of the concrete mixer, and a second leg having a foot to prevent the concrete mixer from rolling away.

A kneader includes a drum and a battery case. An intake port for taking in material to be kneaded is formed in the drum. An accommodation part is formed in the battery case. An opening for inserting a removable battery, or for retrieving the removable battery, is formed in the accommodation part. The battery case is retained in the kneader while oriented in a manner other than an orientation in which the opening faces the drum.
