ES2405280B2 - AGLOMERATE OF OCEAN POSITION FOR USE IN ELEMENTS OF FURNITURE OF BEACH AREAS - Google Patents

Abstract

Agglomerate characterized by using mixtures of oceanic Posidonia residue, water and inorganic or organic binders. The process of manufacturing the agglomerate and its use for the manufacture of furniture in beach areas is also described.

Description

Agglomerate of Oceanic Posidonia for use in furniture elements of beach areas.

FIELD OF THE INVENTION

The present invention is within the field of construction and refers to an agglomerate obtained based on mixtures of Oceanic Posidonia residues and inorganic (cement) or organic binders, intended for the manufacture of furniture elements of beach areas.

STATE OF THE PREVIOUS TECHNIQUE

Due to the waves, Posidonia uplands are periodically deposited on the beaches. The losses of the leaves of these plants are due to the same causes by which the deciduous forests detach from theirs. These contributions are treated, almost exclusively, as organic waste that is transported to landfills "; legalized"; at best, causing significant economic and environmental costs. Special mention deserves the difficulty that these residues present in their compaction and sealing when deposited in landfills due to the mattress effect they produce.

The option of using the Oceanic Posidonia waste as a raw material to manufacture furniture for use in beach areas makes it possible to dispose of this element in the same environment where the waste is generated, managing to solve the environmental problem that is generated Produces when collecting dead leaves of Oceanic Posidonia from the coasts.

Different agglomerate systems are known, all of them made based on the use of plastic and wood materials, mainly. There are others based on silica-quartz or resins. But there are no agglomerates manufactured based on Oceanic Posidonia.

EXPLANATION OF THE INVENTION

It is necessary in the light of the above, to find a solution to the problem of the Oceanic Posidonia residue on the coasts.

20 25

The invention consists in the reuse of this Oceanic Posidonia residue to manufacture furniture elements for use in beach areas. The object of the invention is the product obtained from the mixture of the Oceanic Posidonia residue and organic or inorganic binders. The mixture obtained is an agglomerate similar to those derived from wood, whose main component is the residue of Oceanic Posidonia, agglomerated with cement and water.

As advantages and guiding characteristics of the present agglomerate object of the invention, its resistance, its lightness, the flame retardant properties and its resistance to aging under cycles of

ice-thaw. All this allows the use of chipboard for direct finishes, that is, chipboards seen.

5 1O

Finally, it should be noted that the agglomerate object of the invention provides advantages for the environment, the reuse of the Oceanic Posidonia residue that is currently transported to landfill, thus allowing the recovery of this waste that is currently wasted. Likewise, the reuse of the product obtained in the same place it is generated, can be beneficial to reduce the costs associated with transport and environmental impact.

The use of additives compatible with the binder used is planned.

DETAILED EXHIBITION OF REALIZATION MODES

twenty

The preferred embodiment of the proposed invention is defined by reasons of greater durability, economy and availability of the binders.

Obtaining the product corresponds to an approximate dosage of: Cement: Posidonia: Water ~ 1: 0.82: 1

   25 30

The process for obtaining the agglomerate consists of: a) The residue is screened to remove the sand adhered to the leaves. b) Drying in an oven at 60 ° C for 1 hour, to remove moisture from the leaves. e) It is crushed to reduce the size of the fibers to approximate dimensions of 20 mm in length and 2 mm in diameter.

d) Water and cement are kneaded to obtain a grout. e) The slurry is then mixed with the Oceanic Posidonia residue and the mixture is kneaded. f) After kneading the mixture, it is introduced into a mold to compact it.

g) The compaction of the piece is produced by pressure (depending on the size of the mold, the pressure to be exerted on the piece will be different). The pressure will be approximately 10-15 Kg / cm2.

h) The mixture is allowed to stand for 3 days for proper curing of it.

The use of commercial coloring additives, compatible with the binder used, is provided so that it can be arranged for the purpose of differentiating the different areas and elements manufactured.

The thickness of elements thus obtained is 10-20 mm, but in any case the thickness is not limiting.

The preferred binder for the realization of the mixture is cement type 1 52.5 R.

The different inorganic hydraulic or organic binders used in its manufacture, as well as the shapes and dimensions of the elements obtained will be independent of the object of the invention.

Compression resistance tests have been carried out on 4x4x16 cm prismatic specimens, offering them a compressive strength at 3 days of age of 1O N / mm2. The density of the material is below 1 g / cm3. It is a flame retardant material that absorbs impacts and resists aging cycles of more than 30 ice-thaw cycles.

The agglomerate is designed for the creation of areas on the beaches that allow comfortable accessibility, play areas and services, as well as special attention to the access and use of them by people with disabilities.
