plastics contain Additives (0 to 50%). The average content of additives is 20% by weight of the polymer. Fillers are used to improve performance and to reduce costs. Stabilizers like fire retardants are used to lower the flammability of the material.

Eco-bricks. Experiments were carried out to characterise some of the 6 properties of these bricks. Compression test‚ sound insulation assessment and light 7 transmission were considered in this regard and compared with traditional construction 8 materials and conditions. Possible applications of Eco-bricks were discussed. The paper 9 presents the first attempt to characterise these bricks and the results encourage future use 10 of them to a significantly wider extent and for various purposes.
