Beyond the Gate: Using Lightweight Aggregates in Sustainable Construction
Expanded Shale, Clay and Slate Institute
ESCSI is the association for manufacturers of rotary kiln-produced expanded shale, clay and slate lightweight aggregate.
When used within structural lightweight #concrete mixes or to facilitate internal curing, lightweight #aggregates like expanded shale, clay, and slate can offset production footprint and contribute to more #sustainable #construction.

How Concrete Density Can Impact Seismic Design
American Concrete Institute SmartBrief highlighted the Concrete Products article by Michael Robinson, FACI, Stalite Lightweight Aggregate, a member of the Expanded Shale, Clay and Slate Institute, as the Top Story. The article discusses how the density of concrete affects seismic design. Key points include: Concrete Density and Seismic Performance: Higher-density concrete offers significant compressive strength but can become brittle, which is less ideal for seismic resilience.?Lower-density concrete, like Structural Lightweight Concrete (SLWC), reduces the overall mass of a structure, enhancing its ability to withstand seismic forces. Benefits of SLWC: SLWC can weigh as low as 95 pounds per cubic foot compared to 145 pounds for normal-weight concrete.?This reduction in weight decreases the seismic inertia, meaning the structure experiences less force during an earthquake. Application in Bridges: SLWC has been successfully used in bridge designs in seismic regions, such as the #BeniciaMartinez #Bridge in #California.?The lighter weight helps reduce the forces on structural elements like piles and footings, improving the bridge’s seismic resilience. #ESCSI #Concrete #Lightweight #seismic #earthquake

Join ESCSI and Become A Member
ESCSI offers Producer membership to firms or individuals producing and shipping lightweight aggregates consistently conforming to the current version of Specifications C-330 and C-331 of the American Society for Testing and Materials (ASTM). Such lightweight aggregates shall be produced by expanding and vitrifying suitable shale, clay and slate by the rotary kiln process.
ESCSI offers Associate membership to companies, individuals or organizations that promote or support services to the expanded shale, clay or slate members. Industry associations that support ESCS and whose members include ESCS manufacturers, distributors and suppliers may join as Associate members. Companies or associations that produce or promote alternative products for uses similar to uses of expanded shale, clay or slate are not eligible for Associate membership.
