English: Photographic record taken from an academic paper (2010) written by Ronin and Elfgren. The photo records the large-volume application of EMC made from fly ash onto IH-10 (Interstate Highway), Texas, United States. EMC replaced not less than 50% of the Portland cement in the concrete poured — circa 2.5 times the amount of raw fly ash typically used. The project was approved by TxDOT (Texas, U.S.A) and the U.S. Federal Highway Administration (see, accompanying text in this section).
