1. Introduction. Bricks are a widely used construction and building material. For example, in the United States, about 9 billion bricks are used a year [1], [2].Conventional production of bricks usually utilizes clay and shale as the source material and requires high temperature (900–1000 °C) kiln firing.Quarrying operations for …
