Lightweight Aggregate Plays a Key Role in Pier Expansion
By: Jack Moore, P.E.
To expand Port Canaveral’s Cruise Terminal 3 (CT-3) in Florida, the engineers faced a daunting
challenge: create
structurally secure land over open water in a cost-effective way. To meet these demands, the
team turned to a
lightweight geotechnical fill made from rotary kiln-produced expanded shale and clay.
Using Lightweight Aggregates in Sustainable Construction
By: Bill Wolfe
When used within structural lightweight concrete mixes or to facilitate internal curing,
lightweight aggregates like expanded shale and clay can offset production footprints and
contribute to more ecologically conscious construction.
Enhancing Performance with Internally Cured Concrete (EPIC2)
By: Bill Wolfe
As part of the Federal Highway Administration’s (FHWA) Every Day Counts Initiative, a program
has been developed to
promote internal curing in concrete. The program, titled Enhancing Performance with
Internally Cured
Concrete (EPIC2), was created to demonstrate technologies that help improve the
durability and
longevity of infrastructure.
The Advantages of Lightweight Concrete Masonry Units (LWT CMU)
By: Bill Wolfe
High-performing lightweight aggregates (LWAs) like expanded shales and clays are key ingredients
in producing excellent lightweight concrete masonry units (LWT CMU). A typical LWT CMU weighs
30-40 percent less than normal weight (NWT) CMU and meets all the requirements of ASTM C90
(Standard Specification for Loadbearing Concrete Masonry Units).
The Benefits of Internal Curing with Arcosa Lightweight Aggregates
By: Clint Chapman
Internally cured concrete more readily resists early age shrinkage, curling, warping, and
cracking by supplying water
throughout the concrete mix over time. Internal curing can also increase concrete’s strength and
reduce its
permeability. These qualities help prolong the concrete’s service life, even when placed in
harsh environments.
