Expansive Concretes for Shotcrete in Tunnel Construction

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...
