New Runway 15R-33L and Parallel Taxiway Complex Using Cement, Fly Ash and Blast Furnace Slag as Cementitious Material at Bush Intercontinental Airport of Houston
A new runway complex of approximately 300,000 S.Y. of concrete pavement was designed using a three-way mix of 50% cement, 25% fly ash and 25% blast furnace slag as the cementitious material for the concrete pavement. The design was based on 650 psi flexural strength. The fly ash specified is Class "C" or Class "F" fly ash (ASTMC-618) and the blast furnace slag was specified as ASTMC-989, Grade 120. This runway was designed for Boeing 747's, Antonov 124's and other heavy cargo aircraft. Trial batch runs of the concrete mix indicate remarkable strength gains in 90 days. Flexural strengths of 800 psi were obtained in 90 days, due, in part, the use of 50% pozzolanic materials. The concrete trial batch runs were made using crushed granite rock with a maximum Los Angeles abrasion of 30 maximum. This $100 million project includes storm drainage and sanitary sewer system and airfield electrical work.
