Abstract:
The effectiveness of silica fume to improve the erosion resistance of cement mortars used to repair hydraulic structures was investigated. The mortars were fiber-reinforced and contained a superplasticizer. Other factors investigated were erosion resistance, mechanical properties, shrinkage, atmospheric, under vacuum absorption, freeze-thaw resistance, and adhesion of mortars to concrete substrates.
