The Iowa Portland Cement Company was formed and a plant was built in 1910. The plant was purchased by The Monarch Cement Company, Humboldt, KS, in 1979.
The Des Moines plant operated two kilns and was a wet process plant. After the producing plant was shut down in December of 1985, it became a clinker grinding facility. Clinker from the Humboldt plant was trucked in open top trailers to Des Moines for grinding into finish cement. |
