Description:
Presentation - High Volume Fly Ash (HVFA) portland cement concrete (PCC) was developed to compete with the Tennessee Department of Transportation (TDOT) Class D PCC. HVFA PCC is PCC with at least 50 percent of portland cement (PC) replaced with Class C fly ash. The current TDOT allowable PC replacement rate is 25 percent for Class C fly ash. A higher PC replacement rate would greatly increase the use of an industrial
byproduct thus making more efficient use of natural resources. However, performance and economy cannot be sacrificed for environmental concerns. This paper addresses HVFA PCC performance and not environmental benefits. The results of the research show that HVFA PCC meets or exceeds all TDOT 604.03 Class D PCC property requirements.
