Influence of Silica Fume on the Stresses Generated by ASR

Studies of the pore fluid show that when using silica fume or other pozzolans, alkali concentrations first increase, and then decrease, reaching a low equilibrium value after 20 d to 30 d. In the absence of silica fume or other pozzolans, the alkali concentration increases continuously over time (Duchesne et al. 1994, Dreux et al. 1995).
