Concrete


 * CONCRETE ** is a manufactured mixture of cement and water, with aggregates of sand and stones, which hardens rapidly by chemical combination.




 * REINFORCED CONCRETE **was developed to add the tensile strength of steel to the compressive strength of mass concrete. The creator promoted reinforced concrete for use in railway ties, pipes, floors, arches, and bridges.




 * CONCRETE-SHEEL ** construction permits the erection of vast vaults and domes with a concrete and steel content so reduced that the thickness is comparatively less than that of an eggshel l.




 * PRESTRESSED CONCRETE ** constructions employs bricks, slabs, and supports to increase waterproofing and solidity, to decrease time and cost in erection, and to reduce expansion and contractions. Provides bearing members into which reinforcement is set under tension to produce a live force to resist a particular load. It can carry a great load.



=The Difference Between Tilt-up or Tilwall and Precast Concrete = Tilt-up or tilwall and precast concrete are methods of constructions very alike to each other. The difference between them is basically the place where they are made. First, til-up or tilwall concrete is a process that consists on build concrete panels in assembling forms directly in the work site. This has some advantages like it doesn’t required transportation, but also it depends totally on the weather conditions which can deteriorate the panels in their curing process.

 Now about the precast concrete is a similar process only that these panels are made in other place different from the job site, this allows the panel process of curing quickly and finished correctly. However, this process has consequences; one of them is the issue of the transportation, quarry and distribution of the panels in the work site. So the mainly difference between these two methods of construction is the fact of the transportation of the materials required for the structure of the building and also the final aspect of the building itself.
