Concrete Ground Floor Slab Detail

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.

Concrete ground floor slab detail.

Both pre cast concrete planks or slabs can be used as well as cast in situ reinforced slabs along with beam and block systems. 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. Concrete slab floors come in many forms and can be used to provide great thermal comfort and lifestyle advantages.

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. There are three general types of ground floor construction. They can be insulated both underneath and on the edges. 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.

Aci 302 1r provides guidelines and recommendations on. 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. Wearing concrete slab the floor slab that contains either a square fabric mesh or fibres. For design of slabs on ground with the exception of highway and airport pavements parking lots and mat foundations.

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. 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. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate.

In 1978 nzs 3604 became the standard for slab on ground floors. Integral or separate slab construction was typically. Joints in ground bearing slabs tend to be present for two reasons. 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.
