Concrete Ground Floor Slab Detail

In terms of the buildability most floor slabs have joints within them due to the limits of how much concrete can be poured in a day.

Concrete ground floor slab detail.

1 2 2 aci committee 302develops recommendations for construction of slab on ground and suspended slab floors for industrial commercial and institutional buildings. Joints in ground bearing slabs tend to be present for two reasons. Steel reinforced slabs typically between 100 and 500 mm thick are most often used to construct floors and ceilings while thinner mud slabs may be used for exterior paving see below in many domestic and industrial buildings a thick concrete slab supported on. Slabs can be on ground suspended or a mix of both.

There are three general types of ground floor construction. Wearing concrete slab the floor slab that contains either a square fabric mesh or fibres. Conventional concrete has high embodied energy. Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate.

Foundation wall cast integrally with the slab as an edge thickened slab figure 1 constructed as a separate concrete figure 2 or concrete masonry figure 3 perimeter foundation wall with the slab laid later. Both pre cast concrete planks or slabs can be used as well as cast in situ reinforced slabs along with beam and block systems. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Integral or separate slab construction was typically.

We would like to show you a description here but the site won t allow us. In 1978 nzs 3604 became the standard for slab on ground floors. For design of slabs on ground with the exception of highway and airport pavements parking lots and mat foundations. To ensure a level finish to the floor a layer of screed is added over the top of the concrete which consists of sand and cement.

Concrete slab ground floors in a solid or ground bearing because it is continuously supported by the ground across its whole area concrete floor the choice of insulation position relative to the concrete slab is commonly linked to the building s heating system. Aci 302 1r provides guidelines and recommendations on. A typical way of constructing a solid floor would be to provide a base of hardcore with sand blinding with a layer of concrete over that. Ground bearing floors shall be of adequate strength and durability and use concrete mixed and reinforced as necessary to support floor loads safely and resist chemical and frost action.
