Underground timber constructions from the First World War are well preserved after 100 years
2017 - IRG/WP 17-10897
During the Great War or World War I many underground constructions have been built for protection from shelling. They were an important part of the trench warfare as they were used as an area to rest and carry out other activities such as eating. They would usually range in size from smaller constructions that could hold several men to larger entities that could hold thousands of soldiers. In the ...

Exploration of waterlogged piles and wooden constructions of Riga Dome Cathedral
2017 - IRG/WP 17-10901
The Riga Dome Cathedral’s waterlogged wood piles and the roofs and tower's wooden structures were investigated, the extent of biological damage was evaluated, and the wood rot fungi and insects were identified. The pile wood’s component composition and elemental composition were analysed; the wood structure damage by erosion bacteria was microscopically determined. In the roofs and tower ...

Natural resistance of Bambusa vulgaris to termite and powder-post beetle attack in laboratory and graveyard tests
2018 - IRG/WP 18-10925
Deterioration is the major setback to the utilisation of bamboo products. To enhance bamboo utilization, an understanding of the level of resistance to degradation is important. In this study, level at which Bambusa vulgaris will naturally resistant attack by subterranean termites and powder-post beetles were evaluated. B. vulgaris aged 2, 3 and 4 years were subjected to attack by subterranean ter...

Facile in-situ growth of Ag-TiO2 nanoparticles on polydopamine modified bamboo with excellent mildew-proofing
2019 - IRG/WP 19-30734
Bamboo with good mechanical properties, fast growth rate and low growth cost is one of very utilitarian structural material from forest resources only less important than wood. But it is especially easy to mildew during outdoor service resulting in appearance mould scattering and corrosion. In this work, a facile method was developed to increased mildew-proofinging capability of bamboo. Mussel-ins...

Performance of treated Malaysian semantang bamboo (Gigantochloa scortechinii) - field and laboratory durability evaluation
2023 - IRG/WP 23-30788
Field performance of sematan bamboo, Gigantochloa scortechinii was evaluated under the Malaysian tropical climate, along with laboratory evaluation to white-rot fungi and mold. Starch was removed from the bamboo by submerging the bamboo in the river for 6-8 weeks, kiln-dried and cut to 300 mm (L) round bamboo and 25 mm (W) x 50 mm (L) stripe for the field and laboratory test respectively. Bamboo w...

Manufacturing of bamboo hybrids with high strength, superior fire retardancy, and dimensional stability
2024 - IRG/WP 24-30808
Bamboo, renowned for its rapid growth, high strength-to-weight ratio, and eco-friendly attributes, has found extensive use in decorative building materials and glue-laminated beams. However, the inherent challenges of dimensional instability and flammability in natural bamboo restrict its broad application. This research introduces a range of environmentally friendly techniques aimed at producing ...

Durability of Malaysian plybamboo to mold
2024 - IRG/WP 24-41014
Durability of 3-layer plybamboo fabricated from two Malaysian bamboo species, Gigantochloa levis (beting) and Gigantochloa scortechinii (semantan) using three different adhesives - urea formaldehyde (UF), melamine urea formaldehyde (MUF) and phenol resorcinal formaldehyde (PRF) was evaluated in this study. Samples were exposed to the mold, Aspergillus brasiliensis for 4-week following the ASTM D44...
