摘要: Abstract Fly ash (FA) has been widely used to improve concrete sustainability for many years; however, the amount of FA limited by relatively low cement contents in concrete. In this study, massive volume fly-ash was developed that maximizes use through its as both a and aggregate replacement. Concrete containing much 728 kg per cubic meter produced with compressive strength greater than 30 MPa, permeability measured terms chloride ion (2300C at 56 d) electrical resistivity (60 Ω-m 56 d), decreased environmental impact.
