Clays for the Brick Maker

The manufacturing of high-quality clay bricks begins with a thorough understanding of the raw materials involved-particularly the characteristics and composition of the soil. Among the many variables that influence brick performance, the type of soil and its particle size distribution play a critical role in shaping the physical, thermal, and mechanical behavior of the final product. This book presents a structured overview of the types of soils used in the brick industry, guided by the classification framework provided by the Winkler diagram. The document further explores the significance of clay mineralogy, the role of particle size distribution (PSD) testing, and their implications for raw material selection, process control, and product quality.
