The Superior Portland Cement Company is a former cement manufacturing plant along the Detroit, Toledo & Ironton Railroad in Superior, Ohio.
The Superior Portland Cement Company was organized in 1906 with a capital stock of $10,000, which was later raised to $525,000 in accordance with its original intentions. 7 The company purchased the remains of Center Furnace, which converted raw materials, such as coke or charcoal, limestone, and air into pig iron, 2 and 7,500 acres of land, for $100,000, and erected on the site a cement mill by 1907. 3 The mines featured seams that were six feet thick, and the mill was capable of handling 2,000 barrels per day. 6
The New York Coal Sales Company of Columbus acquired Superior Portland Cement in 1932 and was operated as a wholly-owned subsidiary. 3 The subsidiary was dissolved on January 1, 1949, becoming the Superior Cement Division of the New York Coal Sales Company. The division was sold to Marquette Cement Manufacturing Company on January 4, 1954. 5
Citing labor disputes, Marquette closed its Superior operations in 1986. On March 28, 1988, Kosmosdale purchased the former cement plant and land holdings but never reopened the site. 4
