Cement Concrete - an overview ScienceDirect Topics

A lining of conventional concrete is installed in the final tunnel. The rapid strength development of CAC concrete is particularly advantageous in cold climates and it has been widely used in the Arctic – for example, for grouting cable stays. Even at 0°C CAC concrete can develop strengths of 20–30 MPa at 16 hours (Scrivener and Capmas, 1998).

Concrete Repair - an overview ScienceDirect Topics

Concrete prepared to receive repair concrete should be dry. When a thin layer of repair concrete is to be applied—say, 2 inches thick or less—a bonding agent should be used. Repairs of greater thickness usually do not require a bonding agent. It is best when repair concrete is similar in content to existing concrete.
