| Sumario: | This paper presents the results of investigation of properties of fine-grained concrete on expansive cement for fiber-reinforced shotcretes used for metro tunneling. Basic factors affecting material expansion after mixing with water are described. The influence of expansive components on the values of strength indices and volumetric deformations of shotcrete is studied. Improvement of process, physical and mechanical, and operational characteristics of obtained shotcrete is proven. |
