Structural Lightweight Aggregate and
Concrete - Leading Edge of the Sustainability Movement
John Ries, ESCSI
With its 90-year history, structural lightweight aggregate and concrete now finds itself on the leading edge of the sustainability movement. These materials have a proven track record of conserving energy, lowering transportation requirements, maximizing design and construction efficiency and increasing the service life of the products they are used in. This article examines expanded shale, clay and slate (ESCS). ESCS is a ceramic material produced by expanding and vitrifying select shales, clays and slates in a rotary kiln. The process produces a high-quality ceramic aggregate that is structurally strong, physically stable, durable, environmentally inert, lightweight and highly insulative.
