Concrete


 * CONCEPT:**

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.

What is the difference between tiltwall construction, tilt-up panel construction and pre-cast concrete construction?
The thiltwall construction are assembled and poured directly at the job site, no transportation of panels is required. While the tilt-up panel are created by assembling forms and pouring large slabs of concrete called panels directly at the job site. The panels are then tilted up into position around the building's slab. When temperatures drop below freezing, curing the concrete panels becomes more difficult and expensive. For other side, the pre-cast concrete 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. Because the precast concrete forms are poured indoors, this activity can take place regardless the weather conditions.
