Concrete


 * Concrete ¿What does that mean?**


 * Concrete ** is a manufactured mixture of cement and water, with aggregates of sand and stones, this material changes rapidly to a stonelike, it is water and fire resisting solid of great compressive but low tensile strength.

Difference between **tiltwall construction**, ** tilt-up panel construction ** and **pre-cast concrete construction**

Although these three elements are used to name new or nontraditional cement building processes, they don’t mean exactly the same thing. Firstly, in the process of tilt-up concrete, the walls are created by assembling forms and pouring large slabs of concrete (panels) directly at the job site. The panels are then tilted up into position around the building's slab. On the other hand, tiltwall construction process are assembled and poured directly at the job site, no transportation of panels is required. Secondly, tiltwall panels are normaly standars in their size, but tilt up panels have been measured at just over 69 feet across and almost 93 feet from top to bottom. Then, the precast concrete building process is similar to tilt-up construction, but it addresses the challenges presented by weather. For precast concrete buildings, work crews do not set up forms at the job site to create the panels. Instead, workers pre cast concrete panels at a large manufacturing facility. This process also need transportation, but they got to be smaller and more manageable to allow trucks transport them. To conclude, the three process of concrete construction are obviously similar. But tilt up is more flexible, precast concrete is a good choice in places in which the environments factors and the construction schedule doesn’t permit titwall process as an option.
