   One of the first skyscrapers made with reinforced concrete was the 16-story Ingalls Building in Cincinnati, constructed in 1904. [8] The first reinforced concrete building in Southern California was the Laughlin Annex in downtown Los Angeles, constructed in 1905.

5. Prestressed concrete - Wikipedia

   en.wikipedia.org/wiki/Prestressed_concrete

   Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. [1][2]: 3–5 [3] This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the ...

6. Insulating concrete form - Wikipedia

   en.wikipedia.org/wiki/Insulating_concrete_form

   Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with ...

7. Lift slab construction - Wikipedia

   en.wikipedia.org/wiki/Lift_slab_construction

   Lift slab construction. Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground ...
