industry news
performance applications, from ultra-strong construction materials
to cutting-edge 3D printing techniques. HydroGraph and ASU
have discovered that ultra-low doses of Fractal Graphene (0.02
percent) can enable higher use of supplementary cementitious
materials (SCMs) while delivering up to 70-percent better
early-age performance.
Further, two graphene types produced by HydroGraph, Fractal
Graphene and Reactive Graphene, were incorporated into
cementitious binders at ultra-low dosages (≤0.02 percent by weight
of the binder, rather than the total weight of concrete or cement
mixture) in the study. The addition of HydroGraph's graphene in
minimal quantities led to impressive results, including significantly
improving compressive strength by up to 21 percent after 28-day
curing. The increase in strength enables the use of less cement,
while maintaining the same level of strength, with a reduction of 16.7
percent less cement.

U.S. ARMY ORDERS 683 HEAVY DUMP TRUCKS
Mack Defense announced that the U.S. military has ordered 103
Mack Defense M917A3 Heavy Dump Trucks (HDTs). The additional
vehicles are part of the previously announced firm-fixed price $296
million contract over seven years that the Army awarded Mack
Defense in 2018, which allows for up to 683 trucks. For this new
order, 74 HDTs will be purchased from the presidential budget and
29 are being purchased by the National Guard.
The HDTs play a vital role in construction and upkeep of
infrastructure assets, including airfields, roadways, landing strips,
supply facilities and motor pools.
" Our military continues to field Mack HDTs into various operations
around the world, so these vehicles have been put to the test and
continue to meet demanding requirements, " says Dave Hartzell,
president of Mack Defense. " For that reason, the Army, Army
Reserve, and the Army National Guard continue to invest in these
modern HDTs to ensure our soldiers have the right truck with the
highest level of capabilities needed to ensure mission success. "
The Army previously had ordered 446 HDTs, which are based
on the commercially available Mack Granite model but spec'd
with heavier-duty rear axles, all-wheel drive, increased suspension
ride height, and other ruggedized features to meet the unique
requirements of the U.S. military.

NEW STANDARD FOR STRUCTURAL CONCRETE
The American Concrete Institute (ACI) releases the 2025 edition
of its flagship document, ACI CODE-318-25: Building Code for
Structural Concrete - Code Requirements and Commentary.
This updated edition is now available to ACI 318 PLUS platform
subscribers and will be offered for purchase in print and digital
formats through the ACI Store in early Spring 2025.
ACI CODE-318-25 remains the definitive resource for the
materials, design, and detailing requirements of structural concrete
