Webinar: The Next Generation 3D Printing of Concrete; Measuring the Water Content in Fresh Concrete with the Phoenix

Dr. Tyler Ley

Regents Professor

Gilbert, Cooper, W&W Steel Chair

Oklahoma State University

Tuesday, November 19th

2:00 - 3:15 P.M. (CT)

ABSTRACT

This presentation will cover two topics. The world is facing a housing crisis while natural disasters are increasing in number. Oklahoma State University has developed a novel approach to 3D printing by using attachments to existing equipment such as tractors. This equipment uses ready-mix concrete and prints around typical steel reinforcing. These structures are low-cost and resilient against natural hazards. This technology was used to build several structures that are in use. The second presentation will present a new test method called the Phoenix. This is a new test method that can measure the water content of fresh concrete in 15 minutes. The water content is an important parameter to the consistency, strength, and durability of concrete. The Phoenix is being used by about 20 different agencies with success..
