Item Massive volume fly-ash concrete: A more sustainable material with fly ash replacing cement and aggregates(2015) Rivera, Felipe; Martínez, Patricia; Castro, Javier; López, MauricioFly ash (FA) has been widely used to improve concrete sustainability for many years; however, the amount of FA has been limited by the relatively low cement contents in concrete. In this study, massive volume fly-ash concrete was developed that maximizes the use of FA in concrete through its use as both a cement and aggregate replacement. Concrete containing as much as 728 kg of FA per cubic meter was produced with a compressive strength greater than 30 MPa, a low permeability measured in terms of chloride ion permeability (2300C at 56 d) and electrical resistivity (60 Omega-m at 56 d), and a decreased environmental impact.
