2. 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 ...

3. Foam Index - Wikipedia

   en.wikipedia.org/wiki/Foam_Index

   The Foam Index Test was developed to measure capacities of AEA for cement-mineral admixtures during concrete mixing. [ 2 ] The Foam Index Test is a laboratory titration procedure which determines the AEA absorption on fly ash or fly ash and cement mixtures.

4. 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.

5. Rebar spacer - Wikipedia

   en.wikipedia.org/wiki/Rebar_spacer

   The engineering study of every reinforced concrete construction, whether it is a building, a bridge, a bearing wall, or another structure, dictates the positioning of steel rebars at specific positions in the volume of concrete (predicted concrete cover of steel reinforcement bars). This cover varies between 10 mm and 100 mm.

6. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   Cracks development occurs when early-age concrete is insufficiently protected against desiccation and too much water evaporates with heat because of unfavorable meteorological conditions: e.g, high temperature, direct solar insolation, dry air, low relative humidity, and high wind speed during summer, or in hot conditions. Curing is intended to ...
