Essroc Cement Company: Essroc is a leading cement producer with over 6.5 million metric tons of annual capacity. It is the 8th largest cement producer in the United States. Essroc provides a variety of cement and cement related products including cement for concrete, cement for masonry, colored masonry, chemical admixtures, and ready mix. Essroc's headquarters is located in Nazareth, Pennsylvania. This settlement covers Essroc's six cement plants and nine cement kilns in:
Essroc, which was acquired in a $4.2 billion deal last June, will have signs saying it's part of Lehigh Cement Co. A company spokesman said the mega-deal approved by the Federal Trade Commission last June will have no significant impact on the 175 people who work at the Nazareth plant.
The transaction combined Lehigh Hanson Inc. and Essroc Cement Corp., which were then owned by parent companies HeidelbergCement AG and Italcementi S.p.A., respectively. Now, HeidelbergCement AG is the owner of both Lehigh Hanson Inc. and Essroc.
Cement production in the U.S. amounted to an estimated 92 million metric tons in 2021. Texas, Missouri, California, and Florida were the leading states in terms of cement production in 2021, having accounted for almost 44 percent of U.S. cement produced that year.
In the past week alone, AGC has received reports from contractors and concrete suppliers nationwide documenting quotas, delays and possible layoffs due to cement shortages in Washington, Oregon, Idaho, Nevada, Utah, Wyoming, Oklahoma, Texas, Missouri and Florida.
"What makes these reports especially alarming is that they are coming at the beginning of the high-demand season for cement, meaning more severe problems are almost certain in the near future," said AGC CEO Stephen E. Sandherr.
In addition, some of the states named had no shortages last year, or at least not so early, meaning that shortages are likely to be even more widespread than in the 35 states where the Portland Cement Association noted shortages or tight supplies as of November 2004.
"We urge the Secretary to head off a crisis that could spread throughout the economy by concluding agreements with domestic cement producers to suspend the anti-dumping duty on Mexican cement," Sandherr added.
Mexican cement could reach the U.S. in days by barge or rail, which would reduce congestion and delays for ocean carriers, U.S. ports, and their customers, as well as the construction industry.
Roman concrete, or opus caementicium, was developed over 2,000 years ago. It was used in a variety of structures, many of which still survive today. It’s such a strong material that many buildings made with it have stood the test of time. These famous structures were built using Roman concrete, and stand today not only as a symbol of engineering brilliance, but also as a testament to the durability of this material:
The Pantheon: This unreinforced concrete structure in Rome has stood as a monument to architecture and engineering for nearly 2,000 years.
Mayan concrete at the ruins of Uxmal (850-925 A.D.) is referenced in Incidents of Travel in the Yucatán by John L. Stephens. "The roof is flat and had been covered with cement". "The floors were cement, in some places hard, but, by long exposure, broken, and now crumbling under the feet." "But throughout the wall was solid, and consisting of large stones imbedded in mortar, almost as hard as rock."
Small-scale production of concrete-like materials was pioneered by the Nabatean traders who occupied and controlled a series of oases and developed a small empire in the regions of southern Syria and northern Jordan from the 4th century BC. They discovered the advantages of hydraulic lime, with some self-cementing properties, by 700 BC. They built kilns to supply mortar for the construction of rubble masonry houses, concrete floors, and underground waterproof cisterns. They kept the cisterns secret as these enabled the Nabataeans to thrive in the desert. Some of these structures survive to this day.
