6c2930289c Water beyond that is surplus and is used to make the plastic concrete more workable or easily flowing or less viscous . References. Eventually the excess water evaporates, leaving little pores in its place. Air entraining was introduced in the 1930s and most modern concrete, especially if subjected to freezing temperatures, is air-entrained. The air bubble can be compressed a little, and so the bubbles act to reduce or absorb stresses from freezing. Read more.

MasterAir . Though hardened concrete appears solid, it is actually highly porous, having small capillaries resulting from the evaporation of water beyond that required for the hydration reaction.
The failure of reinforced concrete is most often due to this cycle, which is accelerated by moisture reaching the reinforcing steel. ..
