Holcim’s Trident plant
continues to remain productive
Maintains strong focus on product quality,
safety initiatives and environmental protection
Holcim’s Trident Cement Plant in Three
Forks has been gearing up to celebrate
its centenary in 2010. The plant has stood at
the headwaters of the Missouri River for
nearly 100 years; a century before the construction
of the plant, Lewis and Clark’s epic
journey brought the explorers to the
30 Montana Mining 2009
Headwaters Corridor, an event mentioned in
William Clark’s journal, where he also commented
on the massive limestone formations
in the area. In the years since, those
limestone deposits have provided the raw
material for the millions of metric tons of
cement the plant has produced over its his-
tory. That cement product, in turn, has gone
into the development of much of Montana’s
infrastructure, providing the basic material
for many of the region’s roads, bridges,
buildings and other structures.
Trident’s products are highly regarded for
consistency and quality. The plant produces
traditional ASTM C-150 cements, but is
actively developing new products including
its Envirocore family of products, which
require less energy to produce yet meet the
high demands of the construction industry.
In addition to Montana, Trident cement is
marketed in Wyoming and Idaho and in
Canada, in the provinces of Alberta and
Saskatchewan. The plant’s products are marketed
directly from the plant, as well as
through a system of distribution terminals
stretching from Twin Falls, Idaho, to
Edmonton, Alberta. Customer market segments
for Holcim cement products include
ready mix companies, paving contractors,
block and precast producers, energy (oil)
development, and mining operations.
Holcim’s Trident plant has sustained this
level of productivity with a focus on safety
