Freeze/Thaw Durability of Concrete with Fly Ash

Fly ash, which is a by-product from combustion of pulverized coal, can partly replace the cement in concrete. In AMA Anläggning 07 (2008), which is a guideline for construction of civil engineering structures in Sweden, the content is limited to 6% of the cement content in exposure class XF4 and 11% in the other exposure classes. The performance of concrete with fly ash is in many situations improved compared to Portland cement concretes, but there are fears regarding freeze/thaw durability. The project aims at investigate the properties of concrete with fly ash, with special focus on freeze/thaw durability
