2020-2-7 · Reinforced concrete, concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure.
Concrete is porous; any water which has soaked into the stone will freeze and expand during cold winters, possibly creating fractures. Some ways to prevent cracking are: Concrete sealants: Found in hardware and home improvement centers. They permeate the pores in concrete, helping form a water barrier. There are many sealants available on the ...
