Abstract:
The combination of a reactive concrete aggregate and a regimen of daily washdowns with alkali-containing water resulted in heavy surface deterioration and spalling in concrete elements in a desert power plant. Rapid drying of the concrete elements after the daily washdown resulted in high concentrations of alkali in the pores of the surface concrete. The surfaces were successfully repaired with a latex-modified portland cement mortar; the low permeability of the mortar was further decreased using a silane sealer.
