Concrete

=Concrete=

Definitions:
- Concrete is a manufactured mixture of cement and water, with aggregates of sand and stones, which hardens rapidly by chemical combination to a stonelike, water-and-fire-resisting solid of great compressive but low tensile strength.

- Advantages of Continuity: Absence of joints.

Differences between tilt-up panel construction, tiltwall construction and precast concrete construction:
Tilt-up panel construction and tiltwall construction are expressions used to describe the same process. However, even though tilt-up construction or tiltwall construction are considered similar processes to precast concrete construction, they’re not the same.

The walls for a tilt-up concrete building are created by pouring panels directly at the job site, that’s why tiltwall panels can be extremely wide or tall. On the other hand precast concrete panels require transportation, so they present a limitation on how wide or tall each one can be.

Another difference between tilt-up construction and precast concrete construction is that because tilti-up walls are poured outdoors, they present a very meaningful limitation referring to the weather. That’s when precast concrete buildings come to play an important role in construction, because it can resist better the challenges presented by weather.

Tilt-up is considered the process of choice where weather allows it, because it permits more flexibility. But where the weather conditions aren’t suitable for it, precast concrete is the next choice.
