Variation of air in concrete at different stages of mixing and placement

In cold climates, the freeze-thaw durability of concrete depends heavily on a stable air-void system. This study investigates the impact of hydraulic pumping and the use of supplementary cementitious materials (SCMs)—specifically Class C Fly Ash (CFA) and Rice Husk Ash (RHA)—on the air-void characteristics and rheologi...
