Influence of Fly Ash on Crack Resistance of Mass Concrete

Abstract:

Crack will not only do harm to structure of concrete but also destroy durability of concrete project. The influence of fly ash on crack resistance of mass concrete was studied in this paper. We can decrease brittleness of mortar, elastic modulus, dry shrinkage, adiabatic temperature rising, autogenous deformation and increase creep of concrete by adding fly ash, and present relationship between content of fly ash and elastic modulus of concrete. In short, we can improve crack resistance of mass concrete by adding fly ash.
