The Glen Elder Dam and Spillway is located in Kansas and originally built in 1968. The dam serves many purposes in order to control flooding and create the Waconda Lake which is used for municipal and irrigation water. In 2010, extensive repair and renovations occurred due to freeze-thaw damage which promoted alkali- silica reaction. When new concrete was placed, extensive shrinkage cracking occurred within the first seven days. PREVent-C was chosen as a trial admixture to evaluate its effectiveness on shrinkage cracking. After approval by the US Bureau of Reclamation, the results were impressive. Cracks were completely prevented in two of the test slabs and about 90% reduced in the third slab.
