Alaska Concrete Technologies Inc.

2007 - ACT drove mixer truck, concrete pump and equipment 400 miles to Pogo Mine, which is 60 miles east of Delta Junction, deep in the Alaska Range, to produce and place close to 100 yards of cellular grout.

The owner supplied cement in super bags and ACT supplied equipment, chemicals, and personnel to produce and inject grout under the maintenance shop floor to fill the void.

Low-density grout was used as an insulation barrier between frozen ground and the warm shop floor. In addition to filling the void, the sinking 12 inch thick reinforced slab was also jacked back up about 6 inches, taking 3 days.

2002 - The Fastway plant and mixer truck were driven to Homer, barged, across Cook Inlet to Williamsport, trucked  over the mountains to Pile Bay, and barged across Lake Iliamna to the village of Iliamna to produce 125 yards of concrete for the health center. The contractor supplied local aggregates with cement getting shipped in super bags.

2004 - ACT barged super bags and mixer truck from King Salmon, to Manakotak located on the Igushik River 30 miles from Nushagak Bay, then batched 35 yards for fuel tank base.

Spring 2007 - ACT shipped Fastway plant and 2 mixer trucks by barge and concrete pump by air to New Stuyahok, 60 miles up the Nushagak River from Dillingham to produce and test 1200+ yards of concrete for a school, some in below freezing conditions. All materials were supplied by contractor.

2006 - ACT provided consulting and quality control services on batching silica fume concrete in near-freezing temps for bridge deck at Dutch Harbor which is on Unalaska Island in the Aleutians. Local aggregates were used with cement getting shipped in super bags. Water had to be heated in a tank truck for batching and admixes with silica-fume were added by hand.  

ACT shipped a Fastway batch plant and 1 mixer truck by ferry from Homer to Sand Pt, on Popof Island, near near the end of the Alaska Peninsula for these 2 projects, about 2 years apart. The Community Center took about 200 yards and the Health Clinic took about 400 yards. The contractors on both projects provided local aggregates, with super bags of cement shipped in along with admixes. ACT provided batching and quality control services.

2005 - ACT shipped super bags, mixer truck, and concrete pump by barge to Atka Island which is a long way out on the Aleutians, and batched 150 yards of concrete for a hydro-electric plant.

Super Bags of aggregates and cement as well as concrete pump were flown to the end of the Aleutian Islands. On the first phase, ACT peronnel provided batching and quality control services with ACT-supplied super bags and contractor-supplied mixer trucks and pump.
On the second phase, ACT performed quality control, testing, and consulting, with another subcontractor supplying concrete and pump.

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.
