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. Basement waterproofing - Wikipedia

   en.wikipedia.org/wiki/Basement_waterproofing

   Epoxy crack injections are typically used for structural purposes while hydrophobic or hydrophilic polyurethane injections are used to seal cracks to prevent penetration of moisture or water. Concrete is both strong and inexpensive, making it an ideal product in construction. However, concrete is not waterproof.

4. Asphalt concrete - Wikipedia

   en.wikipedia.org/wiki/Asphalt_concrete

   Sealing small cracks with bituminous crack sealer prevents water from enlarging cracks through frost weathering, or percolating down to the subbase and softening it. For somewhat more distressed roads, a chip seal or similar surface treatment may be applied. As the number, width and length of cracks increases, more intensive repairs are needed.

5. 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 ...

6. Hydrophobic concrete - Wikipedia

   These small particles migrate and concentrate in the small fissures and capillaries formed in the concrete as it dries. As polymerization proceeds, rubber plugs form and permanently seal these water pathways, greatly reducing both water absorption and water permeability. [citation needed]

7. Crack spacing of reinforced concrete - Wikipedia

   en.wikipedia.org/wiki/Crack_spacing_of...

   When a reinforced concrete member is put in tension, after cracking, the member elongates by widening of cracks and by formation of new cracks. Figure 1 Formation of internal cracks. Ignoring the small elastic strain in the concrete between the cracks, we can relate the crack width to the strain of the member by:
