CONCRETE



 **Definitions:** It 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**  Tilt-up and tiltwall are two terms used to describe the same process. For a tilt-up concrete building, the walls are created by assembling forms and pouring large slabs of cement called panels directly at the job site. The precast concrete building process is similar to tilt-up construction, but 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. The precast concrete forms are poured indoors.   Croncrete shell
