Expanded shale aggregate in prestressed concrete
Aggregate produced by heating shale to incipient fusion, when gases formed in material expand and produce numberless small cells, which are still present when material is cooled; each cell is surrounded with hard membrane, highly resistant to penetration of moisture; cellular nature of material is responsible for its resistance to transmission of sound, heat and cold.
