2. Self-healing concrete - Wikipedia

   en.wikipedia.org/wiki/Self-healing_concrete

   Autogenous self-healing crack. Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete.

3. Dowel bar retrofit - Wikipedia

   en.wikipedia.org/wiki/Dowel_bar_retrofit

   The caulking filler is used to prevent backfill material from flowing into the joint or crack. Non-shrink concrete backfill material that is tested as rapid set concrete patching materials is recommended for use on DBR projects. First, make two saw cuts in the pavement to outline the longitudinal sides of each dowel bar slot.

4. Concrete - Wikipedia

   en.wikipedia.org/wiki/Concrete

   Concrete floor of a parking garage being placed Pouring and smoothing out concrete at Palisades Park in Washington, DC. Workability is the ability of a fresh (plastic) concrete mix to fill the form/mold properly with the desired work (pouring, pumping, spreading, tamping, vibration) and without reducing the concrete's quality.

5. Alkali–silica reaction - Wikipedia

   en.wikipedia.org/wiki/Alkali–silica_reaction

   Typical crack pattern of the alkali-silica reaction (ASR). The gel exudations through the concrete cracks have a characteristic yellow color and a high pH. The fatty aspect of the exudations imbibing the concrete porosity along the cracks is also a distinctive feature of ASR. The alkali-silica reaction as a chemical cycle process

6. Self-healing material - Wikipedia

   en.wikipedia.org/wiki/Self-healing_material

   Upon cracking, these particles are exposed to oxygen, and in the presence of heat, they react to form new materials which fill the crack gap under volume expansion. [123] This concept has been proven using SiC to heal cracks in an Alumina matrix, [ 124 ] and further studies have investigated the high temperature strength, [ 125 ] and the static ...

7. Concrete sealer - Wikipedia

   en.wikipedia.org/wiki/Concrete_sealer

   Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
