Concrete ground floor slab detail.

Joints in ground bearing slabs tend to be present for two reasons. The ground floor is made up of suspended concrete slab or beam and block floor supported by the external and internal load bearing walls which transfer the loads to the foundations below. For design of slabs on ground with the exception of highway and airport pavements parking lots and mat foundations. Aci 302 1r provides guidelines and recommendations on.

In 1978 nzs 3604 became the standard for slab on ground floors. We would like to show you a description here but the site won t allow us. Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate. Both pre cast concrete planks or slabs can be used as well as cast in situ reinforced slabs along with beam and block systems.

They can be insulated both underneath and on the edges. 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. There are three general types of ground floor construction. Integral or separate slab construction was typically.

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. Conventional concrete has high embodied energy. Wearing concrete slab the floor slab that contains either a square fabric mesh or fibres. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete.

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. 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. Slabs can be on ground suspended or a mix of both. 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.
