Paul E. Stutzman

Paul E. Stutzman is a physical scientist in the Inorganic Materials Group of the Materials and Structural Systems Division (MSSD) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). Mr. Stutzman operates the Microstructure Laboratory. This laboratory consists of an environmental scanning electron microscope with energy dispersible x-ray analysis, computer image analysis, light microscopy, and an automated x-ray powder diffractometer. The laboratory provides micro-analytical support on research projects conducted by personnel of EL. These projects include the micro-structural and chemical characterization of supplementary cementitious materials such as fly ash, slag, and calcined clays, cement clinker, cement paste, cement paste/aggregate interfacial regions, high performance concrete, concrete, and mortar.

In 1992 and in 2008, Mr. Stutzman received the P. H. Bates Award for outstanding papers, "Cement Clinker Characterization by Scanning Electron Microscopy" and "Phase Analysis of Hydraulic Cements by X-Ray Powder Diffraction: Precision, Bias, and Qualification." These papers were presented at ASTM Symposiums. The purpose of the symposiums were to illustrate new methods and advances in established methods for the characterization of the hydraulic cement, and the application of these methods in cement manufacture. These methods were to aid in the understanding of the relationships between composition and performance, and may have an impact on standards and specifications relating to cement.

Paul is a member of ASTM C1, cement and C9, concrete, chairs the Compositional Analysis Committee, and Task Groups on Microscopy and Quantitative X-Ray Powder Diffraction Methods. He is also a member of the C1 Executive Committee.
