    We will be holding a Free Virtual Presentation for our November meeting.

    SUMMARY: 3D Printing of Concrete” or, Additively Constructed Concrete (ACC), has been demonstrated for structural applications, such as walls in buildings and beams of bridges. These applications require proper reinforcing and anchoring methods to be able to support, transfer, and sustain service loads. However, the field of printed concrete has grown at such a rapid pace that it has been difficult for established construction practices to be accepted by the industry. The use of standardized construction methods for ACC can allow for more ease in the design for engineers and permitting by building officials. ACC introduces new challenges to the placement of reinforcement and the integration with existing technologies. However, the use of more conventional materials and methods will allow for acceptance within current codes and standards. Following this acceptance, alternative reinforcing methods that may be more efficient can later be incorporated as acceptable methods.  The presentation will provide an overview of ACC (Concrete 3D printing) and the approach taken by the US Army Corps of Engineers, Engineer Research and Development Center, Construction Engineering Research Laboratory (USACE-ERDC-CERL).

    Please Register by 5pm on Tuesday, November 3, 2020.

    Webinar login information will be emailed to participants on Wednesday, November 4, 2020.

    The webinar session will open 15 minutes early for announcements.  A Certificate of Professional Development will be emailed to people who request one during the registration process.

    SPEAKER: Eric L. Kreiger, PE ([email protected]) has a diverse background focused on structural engineering, construction materials, construction practices, physics, materials science, and building science. He has experience working in an interdisciplinary environment with architects, engineers (civil, mechanical, materials, building science), and construction professionals. Eric is a licensed engineer and certified as a FEMA/USACE Structures Specialist. Eric is the structural lead for ERDC's additive construction (construction-scale 3d printing) program. Eric is interested in full-scale structural testing of large-scale 3D printed (additive manufactured) components, engineering design and decision analysis using remote data, material degradation, structural assessment using sensors and non-destructive testing techniques, and hazard risk assessment.

    Our next presentation will be a virtual meeting at noon on Thursday, December 3, 2020. Our guest will present the Evolution of Technology for Extending Joint Spacing on Industrial Concrete Floors.
