Composition of material of construction obtained ash of coal fu00d3ssil and resin

摘要

Composition of material of construction obtained ash of coal fu00d3ssil and resin. The invention relates to a composition for construction material comprises a mixture of alternative inorganic solid waste resulting from the combustion of coal, fossil and synthetic resin.The present invention aims at a composition of construction material, which comprises the following alternative content, by weight: 50 to 90% of residues from the combustion of coal, fossil and 10 to 50% of the binder of the type synthetic resins.The inorganic wastes of coal combustion fossil characterized by bottom ash with an average particle size of grains less than 2 mm, with 75% of the grains are between 0.05 and 1 mm.In a first implementation of the invention composition contains the following content by weight: 50 to 70% of residues from the combustion of coal, fossil and 30 to 50% of the thermoplastic resin which is present in solid state. In this composition, the mixture of ashes with the thermoplastic resin can be carried out in the dry state or with the presence of moisture.Preferably, the thermoplastic resin is polyethylene recycled. In a second implementation of the invention composition contains the following content, by weight: 80 to 90% of residues from the combustion of coal, fossil and - 10 to 20% of resins in the liquid state. In this composition, the mixture of ash with thermosetting resin shall be carried out without the presence of moisture.Preferably, the thermosetting resin is polyester, to speed up the action of the resin binder can be used in a commercial synthetic catalyst. Alternatively, the bottom ash may be replaced partially by fly ash, preferably in fractions between 30% and 50% by mass.Still alternatively, bottom ash may be replaced by other households muu00eddos, both natural and artificial, preferably in fractions between 30% and 50% by mass.
