Ash Grove, a CRH company, is a leader and pioneer in the cement industry. For over 137 years, we have provided portland and masonry cements to construct the highways, bridges, commercial and industrial complexes, homes, and other structures fundamental to the nation's economic vitality and quality of life. In 2018, Ash Grove shipped 8.3 million tons of cement from eight cement plants and its network of terminals located throughout the Midwest, Texas and Western United States, and since 2019 is one of the largest cement producers in North America with the addition of operations in Florida, the U.S. Great Lakes and Canada.
In 1824, an English bricklayer patented the product. He called it "portland" cement because he thought it resembled natural building stone found on the Isle of Portland in the south of England. Today, portland cement, stone, sand and water are the basic ingredients of the concrete products with which we build highways, bridges, commercial buildings, dams, residential homes and many of the other structures fundamental to America's economic vitality and quality of life. The modern manufacturing process required to produce portland cement requires complex equipment and machinery, efficient consumption of heat and energy and sophisticated computer and instrumentation technology.
