Abstract: The present invention refers to a new concrete composition comprising fiberglass waste and an air-entraining additive. The concrete presents a thermo-insulating performance far superior to conventionally produced concretes. The present invention is mainly intended for the construction industry, in non-structural applications for thermal insulation. The use of fiberglass waste reduces the consumption of natural aggregates and allows for the use of waste which is expense to dispose of.

Abstract: The proposed invention is a process for obtaining the ore dust suppressant resin with the chemical recycling of Poly thermoplastic polymer (Ethylene Terephthalate) or PET. It is proposed a method for obtaining the resin by using the depolymerization reaction methodology of the Poly polymer (Ethylene Terephthalate) obtained from post-consumption PET bottles, in the presence of cationic surfactant hexadeciltrimetrilamonio bromide (CTAB). The resin is thus obtained being subsequently added to the same PVP K-90 (Polyvinylpyrrolidone) as increasing load on the final viscosity of the resin. Other additives such as lignin extracted from plants such as leaves and tree branches may also be added, in this case, incorporated to make the resin more hydrophobic.
