2. Self-healing concrete - Wikipedia

   en.wikipedia.org/wiki/Self-healing_concrete

   Dry conducted one of the early researches using macroencapsulation, proposing polypropylene and glass fibers with a mono- or multicomponent methyl methacrylate core for healing concrete cracks. [24] The selection of the fibers was prompted by the combination of mechanical strengthening, crack sealing, and a cost-effective encapsulating technique.

3. Concrete cone failure - Wikipedia

   en.wikipedia.org/wiki/Concrete_cone_failure

   Anchors, experimentally show a lower load-bearing capacity when installed in a cracked concrete member. The reduction is up to 40% with respect to the un-cracked condition, depending on the crack width. [7] The reduction is due to the impossibility to transfer both normal and tangential stresses at the crack plane.

4. Fracture mechanics - Wikipedia

   en.wikipedia.org/wiki/Fracture_mechanics

   Concrete fracture analysis is part of fracture mechanics that studies crack propagation and related failure modes in concrete. [17] As it is widely used in construction, fracture analysis and modes of reinforcement are an important part of the study of concrete, and different concretes are characterized in part by their fracture properties. [ 18 ]

5. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   Example of flat piece of concrete having dislodged with corroded rebar underneath, Welland River bridge across Queen Elizabeth Way in Niagara Falls, Ontario. The expansion of the corrosion products (iron oxides) of carbon steel reinforcement structures may induce internal mechanical stress (tensile stress) that cause the formation of cracks and disrupt the concrete structure.

7. Structural integrity and failure - Wikipedia

   en.wikipedia.org/wiki/Structural_integrity_and...

   Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
