Slab-on-ground is the most common type of slab. There are 2 types: conventional slabs with deep excavated beams and waffle pod slabs, which sit near ground level and have a grid of expanded polystyrene foam pods as void formers creating a maze of beams in between.
One-Way Flat Slab
This type of slab is an affordable, simple solution for commercial or residential projects. It's more affordable than other types of slabs, particularly for a ground-level structure. A major limitation to one-way flat slabs is that they don't have the same span capabilities as other slab types.
The major types of concrete slabs used in construction are one-way joist slab, flat slab, flat plate, waffle slab, hollow core slab, precast slab, slabs on grade, hardy slab, and composite slab. 2. What are slab on grade or ground slab? The slab which is cast on the surface of the earth is called a Ground slab.
Standard Concrete Slab Thickness In Australia
In Australia, concrete slabs must be fixed in adherence with the Australian Standards AS 2870 and AS 3600. The most common slab thickness in Australia is between 85mm and 100 mm. The thickness of concrete slabs is usually stated in specification documents.
While quite a few foundation types exist, there are four that are considered the most common. They are the basement, crawl space, pier and beam piling and slab. Basement: The basement foundation is an additional floor partially or completely below ground and built with poured concrete walls.
The most common type of foundation is a slab foundation. It is also one of the most budget-friendly and straightforward to build. As the name suggests, it is a foundation of slab concrete that is around 6 to 8 inches thick.
Overview of the Standard
AS 2870 sets outs the method for determining the classification of a site and the design and construction requirements for slab on ground, stiffened rafts, waffle slab, strip footings, pad footings and piled footings.
In general, 6 inch (150mm) slab thickness is considered for residential and commercial buildings with reinforcement details as per design. Methods used for finding slab thickness varies for different types of slabs.
Standard ready-mix concrete is the most common form of concrete. It is prepared for delivery at a concrete plant instead of mixed on the construction site, which guarantees the quality of the concrete. This type of concrete can provide a structural function, as well as an aesthetic or decorative finish.
Slab-on-ground is the most common type of slab. There are 2 types: conventional slabs with deep excavated beams and waffle pod slabs, which sit near ground level and have a grid of expanded polystyrene foam pods as void formers creating a maze of beams in between.
A cement slab is also generally cheaper than a concrete slab, however the downfalls in strength and durability account for this.
The standard thickness for a concrete slab in residential construction is four inches. Five to six inches may be advantageous if the slab will receive heavy loads, such as a motor home.
Standard grade: The standard grade of concrete includes M25, M30, M35, M40, and M45. The most common concrete grades used to build RCC constructions, including footings, columns, slabs, beams, etc., are M25 to M35.
Using some basic thumb rules, regulations and guidelines as per IS code 456:2000 and ACI code, for concrete floors, concrete slab thickness for residential buildings is kept 4 to 6 inches (100 mm to 150 mm), providing minimum concrete grade M10-M15 and mesh bar embedded in concrete, 2-inch deep from the top of the ...
In Western Australia the most common slab thickness is between 85mm and 100mm.
The Best Type Of Cement For Concrete Slabs
Different types of cement are used to construct concrete slabs, but the best would be Portland Pozzolana Cement (PPC). People use PPC to produce concrete for homes, residential areas, and schools. PPC is made of cement clinker (77%), gypsum (3-5%), and fly-ash (20%).
Australian Standard 1684 (Timber Framing Manual) is the document that specifies the size of sole plates, size of holes and size of stumps. Concrete slabs & strip footings are the most common footing systems used for building in Australia in modern times.
Strip footings are the most common type of footing found in residential homes in Australia.
The National Construction Code is Australia's primary set of technical design and construction provisions for buildings. As a performance-based code, it sets the minimum required level for the safety, health, amenity, accessibility and sustainability of certain buildings.
The footings are the wide pieces of concrete that are placed deep into the ground to prevent movement. The foundation walls are then placed on top of the footings, and resting in between the two is the concrete slab which makes up the basement floor.
Poured concrete is the strongest type of foundation for a house. Concrete is incredibly strong and durable, and it can be poured into any shape. This makes it ideal for supporting the weight of a house. Block foundations are also very strong, but they are not as flexible as poured concrete.
A basement is the most expensive foundation type, and unless you're building a daylight basement—a basement built on a hillside that opens to the daylight on at least one side—this the space created by this type of foundation can feel cave-like, as it lacks natural light.
