A few weeks ago, we talked about post-tensioned slabs, a construction technique that Blues Simon Group uses in some of its projects to -among other advantages- achieve very open floors, with large spans between the pillars. Well, this is not the only technique we resort to for this, since the use of lightweight slabs with the Unidome XS system also contributes to making our constructions distill the elegance of a refined design, which has become our hallmark.
In certain types of buildings, the use of flat slabs –formed with concrete- has become a common practice. These are elements that are supported by the columns –without any other intermediate actor or by means of abacuses-, directly transmitting the loads to them, thus eliminating the need to install beams.
This has been possible thanks to the advances made in the world of engineering and the study of biaxial loads, that is, when the load causes simultaneous bending with respect to both main axes, as happens, for example, in corner columns. The thickness of these elements is usually at least two thirds that of the slab, never less than 10 centimeters if the slab has abacus or 13 centimeters if it does not.
Blues Simon Group relies on Unidome technology, a benchmark in the world of construction, which combines the art of engineering and the understanding of force flows, with the sustainable effort of using a minimum of material to manufacture safe structures. In this way, it fits in with our sustainable philosophy and respect for the environment.
The process couldn’t be faster and easier. Broadly speaking, Unidome concrete formers for slabs consist of two halves, available in different sizes. Before pouring the concrete, these formers are assembled into linear elements of the required length, using two simple reinforcing bars.
The result is slabs with a reinforced concrete platform, in which up to 30% of the concrete in the tensioned areas is replaced, with the consequent benefit in terms of cost and reduction of greenhouse gas emissions that are necessary for production of cement. Not only that, but it is possible to reduce the slab edges by between 5 and 10% compared to that of solid slabs.
Towards the smart construction
The advantages of using this technique, which is not highly recommended in areas of many seismic movements, are multiple. In addition to achieving wide and open spaces, it is very important to note that flat slabs lightened with Unidome XS products have nothing to envy that of solid slabs, regarding their structural behavior, with sufficient capacity to support axial forces. All this, reducing costs and, not least, the carbon footprint of the building by using less concrete and significantly reducing the transport of material.
Blues Simon Group combines this construction technique with that of post-tensioned slabs, as evidenced by the project described in previous articles, or the Altea Hills project, already completed in the core of Sierra de Altea.
It is not only about betting on innovative and sustainable construction products and processes, but also about bringing intelligence to the construction of houses, so that while the construction process is accelerated and costs are saved, are met all specifications and our safety and quality standards are guaranteed.
