2. Dowel bar retrofit - Wikipedia

   en.wikipedia.org/wiki/Dowel_bar_retrofit

   A dowel bar retrofit (DBR) is a method of reinforcing cracks in highway pavement by inserting steel dowel bars in slots cut across the cracks. It is a technique which several U.S. states' departments of transportation have successfully used in repairs to address faulting in older jointed plain concrete pavements.

3. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   The filling of cracks, fissures or voids in concrete for structural purposes (restoration of strength and load-bearing capability), or non-structural reasons (flexible repairs where further movement is expected, or alternately to resist water and gas permeation) typically involves the injection of low viscosity resins or grouts based on epoxy ...

4. Self-healing concrete - Wikipedia

   en.wikipedia.org/wiki/Self-healing_concrete

   The formation of calcium carbonate as a byproduct of microbial activity is an additional method for "engineering" the self-healing ability of concrete. It holds the potential for active and long-lasting crack repair while also being a potentially ecologically beneficial technique.

5. Microbiologically induced calcite precipitation - Wikipedia

   en.wikipedia.org/wiki/Microbiologically_induced...

   The calcium carbonate heals the concrete by solidifying on the cracked concrete surface, mimicking the process by which bone fractures in human body are healed by osteoblast cells that mineralize to reform the bone. [36] Two methods are currently being studied: injection of calcium carbonate precipitating bacteria.

6. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.

7. Corrosion engineering - Wikipedia

   en.wikipedia.org/wiki/Corrosion_engineering

   Corrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to design and implement materials, structures, devices, systems, and procedures to manage corrosion. [1]

9. Fracture mechanics - Wikipedia

   en.wikipedia.org/wiki/Fracture_mechanics

   Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.
