Free-standing, foundationless jib cranes mounted directly on slab-on-grade (SOG) floors are commonly needed in various industries for material handling. However, since industrial floors are subject to stringent serviceability requirements and sudden slab failure can result in dropped loads which can ...
Slab-on-grade foundation Slab on grade used in areas where ground does not freeze. The edges of the slab-on-grade are thicker than the interior of the slab. The slab-on-grade is monolithic (poured all at one time). Frost Protected ...
In both loading cases, the effects of parameters, such as concrete age, notch size, slab size, slab self-weight, day time and night time temperature variation, concrete tensile strength and fracture energy have been conducted. When the slab is under curling-plus-load, it is observed that ...
On-grade plates for joints between on-grade concrete slabs Embodiments of the invention relate to an on-grade joint-stability system for on-grade concrete slabs. Embodiments of the system may include: a first on-grade concrete-slab portion; a second on-grade concrete-slab portion that is separ...

Curling is also exacerbated in industrial floors by the use of power-troweled surface hardeners to produce the dense high-strength top surface required for high wear resistance. Repair of curled floors in industrial locations involves grinding, patching, installation of dowels, and grouting underneath...

Concrete is very strong in compression (density) but weak in tensile (bending) strength, which is why reinforcement is required. Steel rods, called rebars, placed in the lower portion of a concrete slab prevent that slab from cracking when subjected to that tensile bending force. When rebars ...
is at the edges of the slab or at joints that are wide enough to let the slab on either side settle independently. At those free edges, the weight the slab can carry depends on the stiffness of the base and the flexural strength of the slab, which is mostly a function of slab thickne...
