What is Precast Concrete? • Cast into specific shapes at another location • Developed in the late 1960s • First use: stair treads, coping, lintels, and window sills • Known for its high quality architectural products
Manufacture • Casting beds used • High strength steel strands pretensioned • Transverese bulkhead seperators inserted • Additional reinforcement added • Concrete poured and vibrated • Cured with live steam or radiant heat
7. Slabs • The most standardised precast elements • Includes solid flat slab, hollow core slab, double tee slab, and single tee slab
What is in-situ cast concrete? • Concrete that is cast into forms on the building site • Any shape that can be formed can be cast • Certain types of concrete elements cannot be precast, and can only be cast in-situ
22. Selecting an in-situ cast concrete framing system • Are the bays of the building square or nearly square? • How long are the spans? • How heavy are the loads?
23. In-situ Concrete mix • Appropriate concrete properties designed • Appropriate mix design developed • Mixing, transporting and handling coordinated with placing and finishing
24. In-situ concrete placement • Should not be placed more rapidly than it can be spread • Deposit as near as possible to the final position • The concrete is placed in forms and consolidated

Just because this is interesting: beton vs. concrete - how the love of a caring husband inspired the concrete construction:

The first landmark building in reinforced concrete was built by an American mechanical engineer, William E. Ward, in 1871-1875. The house stands today in Port Chester, NY. It is well-known because of the diligence with which Mr. Ward conducted all of his business, researching and documenting everything. He desired a concrete house because his wife was terribly afraid of fire and commissioned architect Robert Mook for the design in 1870. Like Coignet's buildings, it was made to resemble masonry to be socially acceptable. Mr. Ward handled all technical and construction issues himself, conducting long-term load tests and other experiments. He used the French word for concrete, beton, and in 1883 delivered a paper on the house to the American Society of Mechanical Engineers entitled "Beton in Combination with Iron As a Building Material." His audience, by definition, was far more interested in the unique water supply and heating systems, which he had designed, than in reinforced concrete.

In 1879 G. A. Wayss, a German builder, bought the patent rights to Monier's system and pioneered reinforced concrete construction in Germany and Austria, promoting the Wayss-Monier system (Collins, 1959). (Many of these buildings were built in France as well).
