The possible span of a concrete pavement


Reinforced concrete is ideal because of its construction to bridge large spaces. Several factors increase or decrease the span of a concrete pavement. Which ones are they? We recommend the prestressed concrete floor slab as a particularly flexible solution for builders, which can span even large rooms.

Reinforced concrete is ideal because of its construction to bridge large spaces. Several factors increase or decrease the span of a concrete pavement. Which ones are they? We recommend the prestressed concrete floor slab as a particularly flexible solution for builders, which can span even large rooms.

What determines the span of a concrete pavement?

  • Type of concrete floor: pre-stressed prestressed concrete floor, hollow stone ceiling, reinforced ready-mixed concrete, prefabricated concrete elements as a solid ceiling or other systems
  • Traffic load in kN / m2: span decreases with increasing load
  • Type and quantity of installed steel
  • Field width between the reinforcement
  • Type of concrete

Prestressed ready-made ceilings for flexible interior design

Prestressed precast floors are, as the name implies, very extensive. This allows the client to plan his rooms with particular flexibility. In addition, this type of ceiling is installed in a fully assembled manner to save time.

Tips & Tricks

If you decide in favor of a prestressed concrete floor, then inquire about the other technical possibilities before installation: You can, for example, combine your concrete ceiling with a heater or air conditioning system.

FAQ - 💬

❓ What is the maximum span of concrete slab?

👉 Reinforced concrete allows a wide range of structural options and provides cost-effective solutions for a multitude of situations—from residential buildings with moderate live loads and spans of about 25 ft, to commercial buildings with heavier live loads and spans ranging from 40 ft to 50 ft and beyond.

❓ What is a concrete pavement?

👉 Definition: a layer of concrete on such areas as roads, sidewalks, canals, playgrounds, and those used for storage or parking.- ACI Concrete Terminology. Concrete pavement is continuously subjected to traffic and, in some cases, severe climatic conditions.

❓ What is the length of a concrete slab?

👉 In a residential building it is 9 ʺ × 12 ʺ or 225 mm × 300 mm standard size according to (IS codes). The minimum RCC beam size should not be less than 9 ʺ × 9 ʺ or 225mm × 225mm with the addition of a 125mm slab thickness.

❓ How big can a concrete slab be without control joints?

👉 Usually, expansion joints should be no farther apart than 2 to 3 times (in feet) the total width of the concrete (in inches). So for a 4 inch thick concrete slab, expansion joints should be no more than 8 to 12 feet apart.

❓ What is the span of a slab?

👉 Introduction. In structural engineering and architecture, 'span' is the term given to the length of a structural component – eg beam, floor, roof or floor truss – that extends (or 'spans') between two supports.

❓ What is the maximum size of slab?

👉 What is the maximum thickness of RCC slab? According to Indian standard rcc concrete roof slab thickness in residential building construction is 4 inches (100mm). Use of 5″ to 6″ (125mm to 150mm) is recommended if the concrete will receive occasional heavy loads.

❓ How thick is concrete pavement?

👉 Many highway agencies have tight specifications for concrete pavement thickness. Typically, a large reduction in lot payment may result if the concrete pavement thickness is 12.5 mm (0.5 in.) less than specified for as-designed pavement thicknesses in the range of 250 mm to 300 mm (9.8 in. to 11.8 in.).

❓ What are the types of concrete pavement?

👉 Types of Concrete Pavements

  • Jointed Concrete Pavement.
  • Continuously Reinforced Concrete Pavement.
  • Roller Compacted Concrete Pavement.
  • Concrete Overlays.
  • Pre-Cast Concrete Pavement.

❓ What is the maximum span allowed for an RCC slab without beams?

👉 According to IS code 456:2000, the maximum size (length) of the cantilever depends on the effective depth of the cantilever. * The span to depth ratio for a cantilever slab should not exceed 7. * Also maximum size of cantilever provided should be 10m i.e ;length of the cantilever should not be more than 10 meters.

❓ What makes concrete crack?

👉 Shrinkage is a main cause of cracking. As concrete hardens and dries it shrinks. This is due to the evaporation of excess mixing water. The wetter or soupier the concrete mix, the greater the shrinkage will be.

❓ What is the minimum thickness allowed for concrete slab on ground floors?

👉 The thickness of concrete floor slabs supported directly on the ground shall be not less than 31/2 inches (89 mm).
