2. 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 ...

3. Filler (materials) - Wikipedia

   en.wikipedia.org/wiki/Filler_(materials)

   Filler can have a negative or positive effect on fatigue resistance depending on the filler type and shape. In general fillers create small discontinuities in the matrix. This can contribute to crack initiation point. If the filler is brittle fatigue resistance will be low, whereas if the filler is very ductile the composite will be fatigue ...

4. Concrete pavement restoration - Wikipedia

   en.wikipedia.org/wiki/Concrete_Pavement_Restoration

   Dowel bar retrofit (DBR) is a process that re-establishes load transfer capability on joints and cracks by installing epoxy-coated, round steel dowels into existing concrete pavement across transverse joints and/or cracks. Slots are cut using diamond-tipped saw blades; the existing concrete is removed and the dowels are placed in the slots ...

5. Cured-in-place pipe - Wikipedia

   en.wikipedia.org/wiki/Cured-in-place_pipe

   The resins used are typically polyester for mainline lining and epoxy for lateral lines. Since all resins shrink (epoxy resins shrink far less than poly and vinyl ester versions) and because it is impossible to bond to a sewer line with fats, oils, and grease present, an annular space is always created around the new CIPP liner, between it and ...

6. 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.

7. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   This has led to the term modified epoxy resin to denote those containing viscosity-lowering reactive diluents. [21] The use of the diluent does effect mechanical properties and microstructure of epoxy resins. [22] Mechanical properties of epoxy resins are generally not improved by use of diluents. [22] Biobased epoxy diluents are also available ...
