Durability of Sustainable Concrete Mixtures
Use of fly ash in concrete reduces the use of natural raw materials, offers benefits of landfill and CO2 emissions avoidance and therefore contributes to industrial sustainability. This paper presents the results of investigations to determine the various durability aspects of high volume fly ash concrete mixtures, made with ASTM Type I cement and Class C fly ash, yielding a similar 28-day compressive strength to that of Colorado Department of Transportation (CDOT) Class D structural concrete. The durability aspects investigated included the resistance to the chloride-ion penetration (ASTM C 1202), the resistance to the repeated cycles of freezing and thawing (ASTM C 666 Procedure A), and the resistance to the sulfate attack (Mortar bars, ASTM C 1012). It is concluded that the high volume fly ash concrete mixtures are able to exhibit excellent durability characteristics with increased curing time. A concrete mixture with a cementitious material content lower than the CDOT specification and a fly ash content greater than the current CDOT limit, was able to meet Class D structural concrete requirements.
