Taseko Mines Ltd.’s Gibraltar copper-molybdenum mine is located in south-central British Columbia, approximately 60 km (37 mi) north of the City of Williams Lake. Built in 1972, the Gibraltar Mine is the second largest open-pit copper-molybdenum mine in Canada.
As part of the mine’s multi-phase expansion and modernization program, Allnorth Consultants Ltd. provided engineering for the construction of a new four-bay truck shop and maintenance facility. This new area would house Komatsu 930E haul trucks, which weigh 207 tons empty and around 495 tons loaded and have a body capacity of
211 m3 (276 y3).
Without proper wear resistance, the concrete floor supporting such vehicles could easily have suffered wear and tear from abrasion.
To prevent this abrasion, the owner chose to add Kryton’s Hard-Cem to the concrete as they knew it was a proven technology that would increase concrete wear resistance. Adding to the appeal of their choice, Hard-Cem is also fully compatible with conventional admixtures and is the only hardening admixture of its kind currently on the market.
Once added to the concrete mix, Hard-Cem’s full-depth concrete hardening extended the service life of the flooring in the shop and facility, particularly in high-traffic areas that were subjected to long-term abrasion from equipment service and long-term erosion from wash areas. In turn, this prevented costly repairs and replacement and corresponding facility downtime. In short, Hard-Cem proved to be a cost-effective solution for the owner, offering long-term savings with lower maintenance costs while improving the wear resistance of the shop and facility’s floor for employee safety.
Admixture for Abrasion and Erosion Resistance Unlike post-applied surface treatments that delaminate over time, or high-strength concrete that’s prone to curling and cracking, Hard-Cem integral admixture significantly reduces replacement and repair requirements and more than doubles the concrete’s wear life — lowering its embodied carbon footprint over its lifetime.
