Nicolas Ginouse is Research and Development Engineer for King Packaged Materials Company and Associate Professor at Laval University in Canada. His research interests include all the aspects involved in shotcrete technology whereas his expertise contributes to the development of new cementitious materials for mining, tunneling, architectural, and repair applications. Ginouse received his degree in mechanical and industrial engineering from Art et Métiers Paritech, Paris, France, in 2010 and his PhD in civil engineering from Laval University in 2014. He is a member of ACI Committees 506, Shotcreting, and 239, Ultra-High Performance Concrete. William Clements, MASc, P.Eng, is Technical Services Manager for King Packaged Materials Company, where he is responsible for all mixture design development, quality control, and technical support. He received his bachelor’s and master’s degrees in civil engineering from the University of Windsor, Windsor, ON, Canada. He is a member of the American Concrete Institute (ACI) and a member of ACI Subcommittee 546-D, Packaged Repair Materials. He is also a member of the Building and Concrete Restoration Association of Ontario (B&CRAO). Scott Rand is Vice President, Sales, for King Packaged Materials Company, where he is responsible for the Construction Pro ducts Group. Rand has over 30 years of experience in the concrete industry and has spent the past 20 years with King. He has had a major contribution in the growth of the King Shotcrete Solutions brand and its leading position in the North American shotcrete industry. Rand has been involved in high-profile projects in numerous cities from New York to Chicago. He is the 2017 President of ASA and a member of ICRI, UCA of SME, CIM, and ACI. • Low dust and chemical emissions by following best industry practices, closed bulk dry-mix system, predampening equipment and an efficient water atomizer. • Rapid development cycle and accelerated tunnel repairs using ultra rapid strength gain dry-mix shotcrete allowing for much faster re-entry and re-opening to traffic/services. • High-spalling/cracking-resistant shotcrete for challenging ground conditions and protective lining layer using engineered high-performance shotcrete providing enhanced tensile/flexural performance and high-energy absorption.
