Ideal Basic Industries, a Salt Lake-based company, will supply regulated set powder used in repairing two miles of I-15 between Sunset and Farmington.

Even though the cost of using set powder is two or three times that of normal cement, it can save money for areas by setting up quickly and getting freeway lanes back in operation.John Fisher, sales engineer for Ideal Basic, said the regulated set powder is manufactured in Arkansas and the concrete develops high strength in a fraction of the time of normal cement powder.

Preston Gerber, owner of Gerber Construction, said that because between 35,000 and 40,000 vehicles use that section of I-15 daily, this is a pilot program to see how quickly the road can be repaired and cars allowed to run on the new concrete.

Larry Durrant, the Utah Department of Transportation's engineer for the project, said Gerber Construction Co. has a $129,700 contract for the repair work. Besides placing 500 square yards of new concrete, the work includes work on some cracks and putting reinforcing steel in the concrete.

The work will be on a stretch of road where there were major problems last winter. The damaged concrete highway was fixed with asphalt last winter, and that will be removed under Gerber's contract.

Gerber purchased new equipment for the project because the materials must be mixed on the site since they begin setting up in 20 minutes. Within three hours the nine-inch-thick concrete will have a strength of 2,400 pounds per square-inch. It takes concrete containing regular cement powder 28 days to attain a strength of 4,000 to 5,000 pounds per square-inch.

Fisher said regulated set powder originated in the 1960s, and Ideal Basic started making it in 1986. It is becoming more popular today because many miles of concrete pavement need repair and traffic must be restored quickly.
