Title
Cement and Lime Kiln Combustion Technology
Description
Has twenty-five (25) years experience in the cement industry in plant operating, research and development, and corporate management positions. Joined Marquette Cement Company in 1974 as Corporate Quality Manager and moved on to Production and Quality Control Manager at a new 1,000,000 TPY cement plant at Cape Girardeau, Missouri. Joined Ash Grove Cement Company in 1982 to start up a new producing cement plant in Louisville, Nebraska. Became Vice President and Technical Director for Ash Grove in their Overland Park corporate office in 1985 through July 2000. Directed Ash Grove Cement Company's Research & Engineering Laboratory 1985 through 2000 and prior to that time Marquette Cement Company's Concrete Laboratory from 1974 through 1980.
Specific interests in the study of the structure of the minerals in portland cement and how the thermal processing effects the structure and cement performance. Extensive study in combustion technology by installing monitoring equipment for the trace combustion gases. Received U.S. patent for a low NO, burner in 1985. Extensive study of the combustion process in cement kilns led to the study of the substitution of alternate fuels into cement kilns and the effects these have had on cement quality and emissions. These combustion studies led to numerous patents.
Extensive work in the use of amorphous aluminum silicates (metakaolin) in concrete to mitigate ASR and reduce permeability. Based on laboratory work that began in 1993, over 250,000 tons per year of cement containing amorphous aluminum silicate is currently being used in the domestic market. This work has led to issuance of U.S. Patent.
