Mobile Mixer
Mentasta Pass Bridges
Overview
2006-ACT drove a mobile mixer and cement silo 280 miles to Mentasta Pass which is on the Tok Cutoff of the Glenn Hwy 40 miles west of Tok. Aggregates were trucked in 60 miles from Glenallen to produce 600+ yards of State Class A and AA concrete on 2 new bridges.
Chandalar State Maintenance Shop
Overview
2005 - ACT drove a mobile mixer with cement silo 700 miles from Anchorage to Chandalar Maintenance yard, located 340 miles north of Fairbanks at the base of Atigun Pass on the Dalton Hwy. Aggregates and bulk cement were trucked in from Fairbanks to make 300+ yards for a new maintenance shop.

Backfill
Overview
Our Mobil Mixer can discharge sand and 3/4 or 3/8 rock separately or together for backfill in basements, ditches, or walls. Controlled density fills or concrete can be produced immediately afterward with a push of a lever.
Mobile Mixer
Overview
Our 8 cubic yard Volumetric Mixer allows for cost-effective on-site production of concrete for any size project. All of the components-stone, sand, cement, water, and admixes are stored in separate compartments on one truck-mounted unit. The materials are metered and mixed continuously into fresh concrete in a special high-shear auger as the Mobile Mixer is being discharged at up to 60 yards per hour. Because it is mixed as you need it, the concrete does not get old and there is no waste.
Seward Lowell Creek Tunnel Reconstruction
Overview
In 2003 Alaska Concrete Technologies provided 350 yards of 12,000psi+ silica-fume concrete during extreme winter conditions for the Lowell Creek Tunnel Relining in Seward. Even though Seward has ready-mix plants, they did not have suitable aggregates, or experience to procuce 10,000 psi concrete.
Pre-weighed super bags were filled with specially screened aggregates by ACT in Anchorage, and then trucked 150 miles to Seward, along with bags of cement, and admixes. The bags had to be covered and heated and then batched with heated water to produce the high-strength concrete in sub-freezing temperatures.
A portion of the approach flume to the tunnel had water running through porous rocks underneath, creating hydrostatic pressure forcing water up the wall and out cracks. A special expanding grout was used to fill the void and seal off the water.
