For the design and use of full culm bamboo structures, the bending strength perpendicular-to-fibre has received little comprehensive study along the length of commercially produced bamboo poles. We intensively measured the bending strength perpendicular-to-the-fibre for both node and internode sections along the length of commercially purchased Tre Gai (Bambusa spinosa) culms. Eight culms, each four meters long, were sectioned to measure the bending strength terms including tension and compression strengths in both the N-S (top/bottom) and E/W (left/right) directions using ISO 22157 procedures. Digital scanning was used to measure the inner and outer diameter of each section. Node strength was approximately 2.64 times greater than the internode strength. The performances of perpendicular-to-fibre strength terms were related to the primary tissue strength rather than the bamboo fibre strength within the culm. Based upon observations and measurements, the fmT,NS and fmC,EW strengths had greater values with lower variability, and were less sensitive to changes in length.

Conventional kiln drying of bamboo requires extended drying periods. Microwave drying of bamboo has been studied recently and has been reported to be a very fast method of drying. Dendrocalamus asper (Schult. & Schult.f.) Backer is an important, large-sized bamboo, preferred for structural purposes and handicrafts manufacturing. However, it also shows a propensity to develop defects such as cracks during drying. In this study, eight culms of mature D. asper (about 3–3.5 years old) were felled and cut into two halves: upper half and lower half. Both parts were then cut into 900 mm long sections. Twenty sections each from the upper half were dried in a conventional kiln (CKD) at 50 °C and 70% RH; and another 20 sections from the upper half were subjected to microwave-vacuum drying (MWVD) at bamboo wall temperature 60–70 °C and 150 mbar pressure. Similarly, twenty sections each from the lower half bamboo sections were dried using CKD (50 °C, 70% RH), MWVD (bamboo wall at 60–80 °C, 150 mbar) and combination drying in which bamboo sections were first dried in CKD until the moisture content (MC%) dropped to below 30% (26%) and thereafter, further dried using MWVD. The time taken to dry the sections, MC% drop rate, defects, and energy consumption were analysed. MWVD took 12 h (upper half) to 20 h (bottom half) to dry the bamboo sections, whereas CKD took 12–15 days. Combination drying did not offer any major advantages. A lower number of defects were found in MWVD sections compared sections dried by CKD. On average, 3.78 units of electrical energy were consumed for the removal of 1 kg of water from bamboo during MWVD.</div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773139124000090/pdfft?md5=3c97a1fa2042d05a00ed7ae55c307e30&pid=1-s2.0-S2773139124000090-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139985975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Munro) prepared at various temperatures. Savannah bamboo was pyrolyzed at 350°C, 400°C, and 450°C following established procedures to extract vinegar. Gas Chromatography-Mass Spectrometry (GC-MS) was used to characterize the vinegar's ingredients. The British standard EN 252 was used to assess the vinegar's termiticidal efficacy. The greatest amount of vinegar (0.45 kg) was produced at 450 °C. The vinegar mostly comprised hexadecanoic, pentadecanoic, octadecanoic, and (3,3-dimethyl-1-phenylbut-1-enyl) benzene. The proportions of these primary constituents varied depending on the pyrolyzing temperature. With its highest content of fatty acids, the vinegar generated at 450°C had the strongest termiticidal activity.
