Abstract
The present invention is an improved washout pan and method for using it that automatically induces stress at the materials-pan surface interface to induce release of cement-containing materials by the nature of the construction of the washout pan and its response to being moved from a horizontal to a vertical position. The composition of the invention washout pan is critical to the objects of the invention, in that it is preferably formed of polypropylene in a rotomolding process as a single piece with a general overall shape of a box with a slurry body capacity of from 100 to 300 gallons.
