The fire protection agents applied for wooden structures contain ammonium phosphates or sulfates, chlorides, oxides, borates and other metal salts, boric acid, and halogen-containing flame retardants (Seo et al., 2017; Jaskoowski et al., 2013). Many of these chemicals, as well as their ...
New Improvements in Intumescence To ensure the acceptance of fire-retardant treated wood-based composites as engineering materials, their behavior over a range of loading regimes must be fully characterized and understood. Effects of various fire-retardants on plate shear and five-point flexural shear...

(2015) focused on the use of chemical flame retardants, namely sol-gel products, to improve the fire resistance of wooden elements of heritage buildings, without compromising their aesthetical appearance. Furthermore, sol-gel products can protect wood from the effects of weathering and biodegradation...

Nitrogen-phosphate-based salts have been widely used, particularly as substitutes for highly toxic halogenated fire retardants for the fire protection of wood-based materials [26]. However, due to their high water affinity, the resulted fire-retardant treated wood products are mostly used in non-...
The fire behaviour of three biobased composites is presented in Table 1, which reveals the improvement in fire resistance when biobased retardants are added. Over the last decade, polymer composites have been used as packaging materials for food, drugs, household items, etc., to increase their...
