Concrete Ground Floor Slab Detail

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.

Concrete ground floor slab detail.

A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Aci 302 1r provides guidelines and recommendations on. Joints in ground bearing slabs tend to be present for two reasons. In 1978 nzs 3604 became the standard for slab on ground floors.

Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate. They can be insulated both underneath and on the edges. Conventional concrete has high embodied energy. 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.

Integral or separate slab construction was typically. 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. We would like to show you a description here but the site won t allow us. Slabs can be on ground suspended or a mix of both.

Concrete slab floors come in many forms and can be used to provide great thermal comfort and lifestyle advantages. Both pre cast concrete planks or slabs can be used as well as cast in situ reinforced slabs along with beam and block systems. There are three general types of ground floor construction. 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.

Wearing concrete slab the floor slab that contains either a square fabric mesh or fibres. 1 2 2 aci committee 302develops recommendations for construction of slab on ground and suspended slab floors for industrial commercial and institutional buildings. 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. 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.
