Design of Industrial Floors: Principles for Control of Warping.

Abstract: The Slab-on-grade, which include Industrial floors, can be defined, according to ACI Committee 360,1 as a slab continuously supported by ground with an area of more than twice the area required to support the imposed loads. The slab may be plain or reinforced and may include stiffening elements such as ribs and hidden beams. The reinforcement may be provided for structural purpose or for the control of effects of shrinkage and temperature changes. Floar slabs are very important elements ofindustrial facilities. The slab must be uniformly flat and joints must be relatively level without excessive movements to allow manufacturing equipment and fork trucks to perform properly.
