How thick is a bondek slab?
BONDEK PLUS® comes in a variety of thicknesses: 0.60mm 0.75mm, and 1.00mm and provide 550MPa of yield stress strength. This inherent strength means BONDEK® offers top of the class spanning capacities. Embossed ribs at 200mm centres add to the structural and bonding strength with the concrete.
What is bondek slab?
BONDEK® is a highly efficient, versatile and robust formwork, reinforcement and ceiling system for concrete slabs. It is a profile steel sheeting widely accepted by the building and construction industry to offer efficiency and speed of construction.
How wide is bondek?
USING LYSAGHT® BONDEK® STRUCTURAL STEEL DECK It has re-entrant ribs into the concrete slab at approximate 200mm centres and its depth is 54mm. It is available in a Base Metal Thicknesses (BMT) 0.6, 0.75, 0.9 and 1.0mm.
Is bondek fire rated?
The performance of BONDEK has been improved from recent analysis and confirmatory testing for formwork spanning and fire design. Most suitable for thin slabs up to 120mm. Slab can be designed for fire rating of up to 90 minutes without additional fire reinforcement.
How thick should a suspended concrete floor be?
This depends on site conditions and the type of project. A typical concrete slab can be between 100 to 500 mm in thickness and will be steel reinforced. SUSPENDED REINFORCED CONCRETE DESIGNS: There are different designs used for suspended reinforced concrete slabs.
How do you calculate concrete slab thickness?
Standards like ACI 318 have specified the minimum thickness of the slab based on the span of the slab.
- Simply Supported Slab = Span / 20.
- One End Continuous Slab = Span / 24.
- Both End Continuous Slab = Span / 28.
- Cantiliver = Span / 10.
How thick of a concrete slab do I need?
How Thick does a Concrete Slab need to be? For residential properties, a concrete slab needs to be at least four inches thick to comply with building codes. An additional two inches are recommended if your concrete will regularly receive heavy loads like motor homes or garbage trucks.
How much weight can a 6 concrete slab hold?
A 6-inch concrete slab with a 700 psi compression strength can hold 1,105 psi of pressure. In 7-inch thickness, it could sustain 1,194 psi, while in 12-inch thickness, it could support 1,563 psi.
What is the ideal thickness of concrete slab?
4 inches
Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
What is the minimum thickness of footing?
3.8. (1) states: 1) Footing thicknesses shall be not less than the greater of a) 100 mm, or b) the width of the projection of the footing beyond the supported element. 2.
