ESCSI Plays Pivotal Role in NRMCA’s EPA Grant for EPD Development
The Expanded Shale, Clay, and Slate Institute (ESCSI) is set to play a crucial role in the National Ready Mixed Concrete Association’s (NRMCA) recent $9.63 million grant from the U.S. Environmental Protection Agency (EPA). This grant, part of the broader Inflation Reduction Act, aims to reduce embodied greenhouse gas emissions in construction materials by developing and verifying Environmental Product Declarations (EPDs). ESCSI’s involvement is expected to significantly enhance the project’s impact, particularly using lightweight aggregates.

McDonald Creek Bridge in Glacier National Park Utilizes Internal Curing
The Federal Highway Administration’s Western Federal Lands Highway Division and Glacier National Park partnered on a project to replace the Upper McDonald Creek Bridge in Glacier National Park, near Kalispell, MT, with a double-lane, clear-span bridge utilizing Internal Curing technology (ASTM C1761). Internal curing dramatically reduces the cracking in concrete which leads to increased service life of these bridges and pavements.
More Floors, Less Dead Load: Building Bigger With Structural Lightweight Concrete
The original structure for the Union Station parking garage in Washington, D.C., was designed for a four-level vertical expansion. By utilizing lightweight concrete, the designer, THA Consulting, provided five levels at approximately the same vertical loads (Historic Union Station Garage Expansion – THA Consulting Website).
Lightweight Aggregate Improves Illinois Bike Path Extension
“The site of the trail is in a swampy, marshy area bordering a large drainage ditch and a pond,” says Kevin Cavanaugh, Arcosa Lightweight’s former technical sales & marketing representative who consulted on the project. “There was also a steep slope running alongside the trail to contend with.”

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.
