Reinforced concrete slabs are one of the most common building materials. Such a slab is a monolithic concrete block, inside which there is a reinforcing cage, as well as along the entire length - voids of a round shape, to prevent deformation and facilitate the slab itself. The use of floor slabs simplifies construction and provides a shorter construction time.
The characteristics of reinforced concrete slabs affect their price and functionality . These characteristics are listed and described below.
Dimensions.
The length of the slab varies from 2.4 to 6.6 meters. Width - from 0.6 to 2.4 meters. The thickness of these plates does not vary, and becomes 220 millimeters. The weight of a reinforced concrete slab can reach 2.5 tons.
Estimated load.
Reinforced concrete slabs exist mainly of two types, if we take the design load as the criterion. For residential buildings, a load of 300 to 450 kgf /m2 is used. And for industrial or for public buildings, plates up to 800 kgf /m2 are used. The price of the slab depends on the design load.
Depth of support for the ends of reinforced concrete slabs.
This is also an essential characteristic of this building material. The depth of the end support should be between 90 and 120 mm. This characteristic is measured by having mortar pads, which are designed for horizontal, even laying of slabs.
These are the main characteristics of reinforced concrete slabs, but there are additional ones, which are also important when choosing a slab. When buying a slab, you may notice cracks, but if their opening is less than 0.3 mm, then this will not be a problem. It is also necessary to know that it is not recommended to store reinforced concrete slabs outdoors for a long time.
Plates can also be solid. When overlapping balconies, or when building cottages, it is worth using just such plates. In addition, there are solid aerated concrete slabs and ribbed reinforced concrete slabs.
