scaling
Building materials; Concrete
The local flaking or peeling of a hardened concrete surface , usually less than 1/8 th inch, caused primarily by hydraulic pressures from freeze-thaw cycles affecting the concrete at the surface.
rich mix
Building materials; Concrete
A mortar or concrete mix with a relatively high cement content. Fat mix is more easily spread and worked than a mix with the minimum amount of cement required for strength.
release agent
Building materials; Concrete
Material used to prevent bonding of concrete to a surface, such as to forms.
retardation
Building materials; Concrete
Delaying the hardening or strength gain of fresh concrete, mortar or grout.
retarder
Building materials; Concrete
An admixture which extends the setting time of cement paste, and therefore of mixtures such as concrete, mortar, or grout.
retempering
Building materials; Concrete
The addition of water and remixing of concrete which has started to stiffen: usually not acceptable as it may affect the ultimate strength.
saponification
Building materials; Concrete
The deposit of a gray scum or gray dust on the inside surface of a sub-grade wall or floor as the result of moisture moving through the concrete and washing certain chemicals from the concrete mass.
