3. Rebar spacer - Wikipedia

   en.wikipedia.org/wiki/Rebar_spacer

   Plastic has mechanical properties (holds the bar in position) but no structural properties, and is a foreign element within the construction. When the concrete is poured into the form, a small gap is created between the concrete and the plastic. Plastic has a coefficient of thermal expansion and contraction 10 to 15 times that of concrete. [1]

4. Arching or compressive membrane action in reinforced concrete ...

   en.wikipedia.org/wiki/Arching_or_Compressive...

   Park's approach was later extended by Park and Gamble [9] in their method for predicting the plastic load-deformation response of laterally restrained slabs. In 1971, the American Concrete Institute [ 10 ] produced a special publication which presented the most recent research, to that time, on arching and compressive membrane action in ...

5. Waffle slab foundation - Wikipedia

   en.wikipedia.org/wiki/Waffle_slab_foundation

   Waffle slab foundations adhere to International Building Code requirements. By 2008, most states put into effect the changes adopted in the 2006 IBC and, in regards to foundations, the on-grade mat foundation has become a more attractive design because, as an engineered system, it already accommodates the 2008 design recommendations, and required no major modifications to bring it into compliance.

   At the same time Ransome was inventing twisted steel rebar, C.A.P. Turner was designing his "mushroom system" of reinforced concrete floor slabs with smooth round rods and Julius Kahn was experimenting with an innovative rolled diamond-shaped rebar with flat-plate flanges angled upwards at 45° (patented in 1902).

7. Concrete slab - Wikipedia

   en.wikipedia.org/wiki/Concrete_slab

   A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below). [1] [2]

8. Grade beam - Wikipedia

   en.wikipedia.org/wiki/Grade_beam

   Grade beam. A grade beam or grade beam footing is a component of a building's foundation. It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons. [1]

   He formed his own company in 1901 and received a patent in 1908 for an innovative flat-slab support system, known as the Turner System or the Spiral Mushroom System, using reinforced concrete, although this patent was invalidated in 1915 and 1916 in favor of similar patents filed by American engineer O.W. Norcross.
