ABSTRACT:
A method for delivering a pre-weighed package comprising sand, aggregate and dry cement to a mixing site comprises the steps of preparing a first mixture comprising fine aggregate and coarse aggregate at an offsite plant. The first mixture is placed into a first storage compartment of a hopper and the load of dry cement is placed into a second storage compartment of the hopper. The hopper is transported to the mixing site, where the first mixture and the cement are discharged from the hopper and mixed to form a concrete slurry. The hopper comprises the first storage compartment and the second storage compartment, where there is a water tight divider separating the first storage compartment and the second storage compartment. The storage compartments have respective inlets and outlets for receiving and discharging the respective components.
