Gray Powder Technologies Inc. was founded in 1995 by Lonnie Cook. Lonnie gained valuable experience working in the cement industry for thirty years and was instrumental in running one of the largest alternative raw material programs in the country.

Lonnie has brought that same vision to GPT and we now provide raw materials to over fifteen cement companies and provide by-product placement services to nearly fifty industrial companies. GPT also provides consulting services to many cement plants and other companies throughout North America.

GPT as a company has grown at a rapid pace by offering our customers individual customer service, attention to detail, and bottom line savings. Our staff has many years of experience in the cement and related industries.

GPTs Corporate office is in Muscatine, Iowa. Our sales staff is located near their customer base. We service accounts throughout the United States, Canada and Europe.
