The unique properties of
expanded shale, clay and slate, ESCS, ceramic lightweight aggregate provides
time-tested sustainable
performance. This material offers economical and environmental
engineering solutions in structural
concrete, geotechnical,
asphalt, concrete masonry, and other applications.
General Information
Literature
What is ESCS Ceramic Lightweight Aggregate?
ESCS is a unique
lightweight aggregate prepared by expanding select minerals in a rotary kiln
at temperatures over 1000°C. The
production and raw material selection
processes are strictly controlled to insure a uniform, high quality product
that is structurally
strong, stable, durable and inert, yet also lightweight
and insulative. ESCS lightweight aggregate gives designers greater
flexibility in
creating solutions to meet the challenges of dead load,
energy budgets, terrain, seismic conditions, construction schedules and
budgets in today’s marketplace.
Brief History
For nearly a century
Expanded Shale, Expanded Clay and Expanded Slate has been used successfully
around the world in more
than 50 different types of applications. The most
notable among these are SmartWall lightweight concrete masonry units,
high-rise
buildings, concrete bridge decks, high performance concrete, HPC,
precast and prestressed concrete elements, marine platforms,
asphalt
bituminous surface treatments, lightweight chip seal, soil conditioner and
lightweight geotechnical fills.
Expanded shale, clay and
slate structural lightweight aggregate, SLA, as manufactured by the rotary kiln process was
originally
developed in 1908 and patented in 1918 as Haydite. Today SLA is
available throughout the world.
ESCS ceramic lightweight
aggregate improves concrete in several ways. The most notable are weight
reduction and the ability to
design with specified density concrete. ESCS also provides moisture
for
internal curing which
improves the quality of concrete.
Expanded Shale, Clay & Slate Institute, ESCSI
ESCSI is the international
trade association for manufacturers of rotary kiln-produced expanded shale,
expanded clay and expanded
slate lightweight aggregate. ESCSI promotes the
extensive use of rotary kiln-produced lightweight aggregate in the
lightweight
concrete masonry and structural lightweight concrete markets, as
well as use in asphalt, geotechnical and other applications.
Based on
research and development, educational material is disseminated to all
phases of the building industry. The association
works closely with other
technical organizations, ACI, ASTM, etc. to maintain product quality,
life-safety and professional integrity
throughout the construction industry
and related building code bodies.
