Studies on Repairing of Concrete Cracks with Epoxy Resin

Journal of the Society of Materials Science, Japan, 1967
Cracks appearing on concrete or mortar of structures would reduce the life of structure and destroy its functions, because they cause permeation or penetration of air and moisture. For example, water permeation and air penetration through such cracks promote a corrosion of steel frames and bars.As a procedure to avoid such unfavorable consequences ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...
