Encapsulated lightweight polymer aggregates

A lightweight aggregate for use in forming lightweight cementitious mixes and/or concrete is formed by encapsulating a plurality of hydrophobic polymer particles (e.g., expanded polystyrene particles) in an encasement having a first layer of a cementitious material and a second layer of a pozzolan o...

Beschreibung
Zusammenfassung:	A lightweight aggregate for use in forming lightweight cementitious mixes and/or concrete is formed by encapsulating a plurality of hydrophobic polymer particles (e.g., expanded polystyrene particles) in an encasement having a first layer of a cementitious material and a second layer of a pozzolan or mineral. The lightweight aggregate can be included as at least part of the aggregate component of a cementitious mix to form a lightweight cementitious mix. The lightweight aggregate and/or lightweight cementitious mix can be used to form lightweight concrete. The encasement of the lightweight aggregate allows the cement of the cementitious mix or concrete composition to bond to the lightweight aggregate, thereby promoting strength and durability of the concrete mixture.
