Abstract:
Since 1994, over 500 concrete panels on Runway 16C/34C at the Seattle-Tacoma International Airport were replaced with slabs constructed with belitic calcium sulfoaluminate cement concrete. The article discusses evaluation of these slabs after about 23 years in service, including compressive and flexural strength, chemistry of the pore solution, and concrete microstructure.
