Existing experience on electrochemical methods for the rehabilitation of corroded reinforced concrete structures (RCS) shows that chlorides can be removed from these structures and that carbonated concrete can be realkalised. However, the current state of know-how has not advanced sufficiently to...
Four cements were used to address the effect of tricalcium silicate content of cement on external sulfate attack in sodium sulfate solution. The selected cements had similar fineness and Bogue-calculated tricalcium aluminate content but variable tricalcium silicates. Durability was assessed using...
Today, in the field of underground constructions, alkali-free accelerators are commonly employed, during tunnel excavation, to allow flash concrete setting. In this way, the cementitious sprayed material can firmly bond to the tunnel walls, controlling the convergence (the tendency of the section...
