A waste container for the disposition of waste concrete comprising a bottom floor section having a major dimension extending longitudinally of the container, front and rear lateral dimensions which are substantially less than the major longitudinal dimension, and a forward end closed by a forward transverse wall section. Opposed side walls extend longitudinally of the container and upwardly from the bottom floor section to define with the bottom floor section a receptacle for waste concrete. The side walls are flared from the front to the back of the container to provide a back opening which has a lateral dimension greater than the lateral dimension of the forward transverse wall section. The side walls are sufficiently flexible to permit relative displacement between a first lateral dimension corresponding to the configuration of the side walls when they are not stressed and a second lateral dimension which is less than the first lateral dimension. A reconfiguration system is connected to at least one of the side walls and effective to compress the lateral dimension of the side walls relative to one another from a first somewhat greater lateral dimension to the second reduced lateral dimension when a plastic mass, such as unset concrete or the like, is added to the container.
