NRMCA's celebration of the 100th anniversary of ready mixed concrete in the U.S. continues its submissions for December - see below for this week's Producer and Associate member Web site links. This week's industry milestone: In 1992, Southern Illinois University at Edwardsville developed concrete kits for elementary schools to demonstrate the science of concrete and to introduce basic engineering principles.

Rohrer’s Quarry Inc. - Thomas H. Erb opened a limekiln on his farm just southwest of Lititz, PA, in the middle of rich deposits of limestone. This site remains the location of what is now Rohrer’s Quarry. Many kilns served Lancaster County, which was almost entirely agricultural at that time. They supplied farmers with lime for their fields and whitewash for their barns and fences. There were no paved roads or buildings constructed of concrete at that time. These two developments will eventually change the operation’s focus. Limestone was quarried by hand from a small pit and loaded into the kiln’s funnel-shaped interior alternated with layers of wood. The contents were burned for one to three weeks and then left to smolder. When cooled, the white, soft chunks of lime could be removed and pulverized for spreading on neighboring farms. Read more.
