Alamo Cement Company has a very long and rich history. At a time when the cowboys roamed the West, a small Texas cement company laid a solid foundation for its existence. Started in 1880, the original cement plant, known as San Antonio Portland Cement Company, was located at what is now called the Japanese Tea Garden. In 1908, the cement plant relocated to North Central San Antonio what is now known as the Quarry Market. In 1979, the San Antonio Portland Cement Company was renamed Alamo Cement Company, and today we are part of the Buzzi Unicem family of companies. Globally, Buzzi Unicem SpA operates in 14 countries and employs almost 10,000 people. From 1909 to the late 70's, many technological advances in cement production had taken place. Wanting to take advantage of these improvements, Alamo Cement Company initiated the construction of a modern plant located in the Northeast area of San Antonio. Retaining the name Alamo Cement Company and became fully operational in 1981. Producing and providing Type IL, Type III, Masonry N and Masonry S cement to the Texas market.
