More Information
Summary:A lightweight aggregate comprising a sand and cement accreted onto a nucleus particle of expanded polystyrene which is coated with molasses to aid accretion and a clay accreted onto a nucleus particle of combustible vegetable material. The sand and cement may include powdered and granular expanded polystyrene to further lighten the aggregate and the clay may have finely divided vegetable matter admixed. The vegetable matter nucleus and admixture to the clay is carburized and volatilized when the clay is fired. Subsequent layers are accreted using different raw material in each layer, to make an "onion effect". Several lightweight aggregate particles are agglomerated in larger overall particles using a bonding agent.
