Mr. Niels Thaulow is a senior scientist at RJLG. He is a chemical engineer who, over a career of nearly 40 years, has gained international recognition as an expert in the durability of concrete. He is an experienced petrographer whose work includes analyzing over 20,000 thin sections of concrete. He has, since 1967, spearheaded the development of techniques for optical petrography and scanning electron microscopy for the examination of concrete. He has independently developed new methods for assessing the properties and quality of concrete.Since Mr. Thaulow started working at RJLG in 2000, he has been in charge of numerous laboratory and field investigations of damage to concrete and reinforced concrete structures subject to a wide variety of exposure conditions. Such projects include investigations of highway bridges (with extensive exposure to de-icing salts), residential structures, swimming pools, dam structures in hot, humid climates, and numerous marine structures. He has analyzed concrete structures world-wide including Europe, Africa, Australia, The Far East, Middle East and North America. A large portion of his work has been concerned with alkali silica reactions and other durability problems experienced by structures exposed to chlorides or other aggressive substances such as sulfates. Mr. Thaulow is involved with numerous societies, including the following: Danish Society of Engineers, Danish Concrete Society, Danish Chemical Society, Danish Materials Research Society, Danish Society of Concrete Petrography, International Union of Testing and Research Laboratories for Materials and Structures, American Concrete Institute, American Ceramic Society, American Society for Testing and Materials, and Materials Research Society. He has published in peer-reviewed literature. |
