Superior Portland Cement Company

The Superior Portland Cement Company was a cement manufacturing plant located along the Detroit, Toledo & Ironton Railroad in Superior, Ohio.

The Superior Portland Cement Company, established in 1906 with an initial capital of $10,000, later increased to $525,000, purchased the remnants of Center Furnace 2 and 7,500 acres of land for $100,000. 7 By 1907, the company had constructed a cement mill on the site. 3 This mill, situated alongside rich mineral seams six feet thick, had a production capacity of 2,000 barrels per day. 6

In 1932, the New York Coal Sales Company of Columbus acquired Superior Portland Cement, operating it as a wholly-owned subsidiary until it was dissolved on January 1, 1949, to become the Superior Cement Division of the New York Coal Sales Company. 3 This division was later sold to Marquette Cement Manufacturing Company on January 4, 1954. 5

Marquette Cement Manufacturing Company closed the Superior facility in 1986 due to labor disputes. In 1988, Kosmosdale purchased the property and the former cement plant, but the site was never reopened. 4

My father worked at this plant in the 50’s and 60’s when it was renovated from the original turn of the century plant to a modern state of the art plant. The plant was closed because the principal raw material, limestone, ran out and was having to shipped in by rail. I was at the plant many times during its construction and operations. My family has lots of photos from the plant during that time. In the late 60’s it had one of the largest boom shovel in the USA.

James Stine here. I noticed in your reply you mentioned the 5323 shovel that worked at the limestone mine for the cement plant. I am seeking more information about this shovel and some photographs of it if possible. I would like to talk with you about this if it is ok. My number is 814-701-5960. I am a stripping shovel historian and have been for 30+ years. I have a very large collection of stripping shovel material and am trying to complete a file on the 5323 shovels. I would like to hear from you. Thank you for your time.

His name is Roy Clayton (tommy) DePriest if you could help me in anyways I would greatly appreciate it!


I was there last night.. It's an interesting exploration. A lot of the premise has been demolished, but there's still plenty to see. I totally recommend a visit.

I was out there on 10-25-10 and it looks like the demolition has begun. I was there last summer and A LOT has been torn down since then. The offices and the brick building are gone and part of the metal structure is as well. Scrap metal, maybe? If you want to see it you should go soon before it's gone!
