Examining The Effects Of Reducing The Cement Content Of Portland Cement Concrete Pavement, Bryan Casillas
Examining The Effects Of Reducing The Cement Content Of Portland Cement Concrete Pavement, Bryan Casillas
Graduate Theses and Dissertations
Portland cement is a significant component in a concrete mixture. For concrete used in portland cement concrete pavement (PCCP), the Arkansas Department of Transportation (ARDOT) specifies a minimum cementitious material content of 564 lb/yd3 and a maximum water-cementitious material ratio of 0.45. Prior research conducted at the University of Arkansas, TRC 0603, indicated concrete mixtures used in five bridge decks throughout Arkansas achieved the required 28-day strength at seven days, and the measured compressive strength at 28 days was 30% greater than required. The use of high strength concrete in pavements throughout the state can increase cracking and consequently reduce …
