  • Lightweight Expanded Clay Aggregate an overview

    Expanded clay, shale and slate Bricks are produced by the drying and firing of clay or shale raw material, forming a sintered porous structure Similarly, the drying and sintering of pelletised clay or shale can produce a usable aggregate, but more especially if the raw material is capable of being ‘bloated’ Some forms of clay or shale contain organic or mineral matter which can release gases on heating, leading in the appropriate conditions to bloating or expansion of the pelletised particles 335 ‘Lightweight expanded clay aggregate’
