The average moisture content of fresh bamboo (cv. Dendrocalamus stocksii) after harvesting was found to be 58.33 per cent. The shrinkage of bamboo along diameter, thickness and length varied between 2.90 to 5.43 per cent, 3.02 to 10.88 per cent and 0.04 to 0.73 per cent, respectively. Thus, it was found that the shrinkage in thickness was more than diameter and that of shrinkage in thickness was more than length wise. The top portion of bamboo provides more compression and shear strength than bottom portion. The high compression strength was found for smaller length of bamboo as compared to larger length. It was also found that with node bamboo possessed more compression and shear strength than without node and six month old harvested bamboo possessed more compression strength than fresh bamboo.Keywords

The demand of wood products is continuously increasing in spite of rapid depletion of forests around the globe. Water absorption and desorption in wood are of practical importance since they also affect the mechanical properties of the product. The five wood varieties teak, beechwood, mango, jackfruit and ain were used for study that are popular for timber and furniture in Konkan. These five varieties showed initial high rate of moisture uptake and drying followed by comparatively slower rate. Drying rate was eight times higher than absorption process. Shear strength of all wood varities decreased with increase in moisture content.Keywords

Three varieties of bamboo viz., Dedrocalamus ritchy (Manga), Dendrocalamus stocksii (Mes) and Dendrocalamus strictus (Manvel) were used to prepare bamboo mats were weaved manually and treated with glue. Urea formaldehyde (resin) was used as glue to prepare bamboo mat boards. The resin application was done by dipping. Bamboo mats were dipped for 10 min in urea formaldehyde. 30 kg of resin was required for complete dipping of bamboo mats. Mats were pressed together at 110°C temperatures and pressure of 150 kg/cm2 was applied for 5 min. This is for spreading glue properly. Mats were again pressed at 110°C at a pressure of 200 kg/cm2 for 10 min to from bamboo mat boards. Boards were trimmed to a size of 2.1 m × 1.2 m board of 9 mm, 12 mm and 16 mm thickness were prepared. Bamboo mat board can be prepared from Dendrocalamus stocksii (Mes), Dedrocalamus ritchy (Manga) and Dendrocalamus strictus (Manvel) using urea formaldehyde resin. Dedrocalamus ritchy (Manga) was easy to prepare slivers of bamboo. Density of bamboo mat board increased as thickness increases. Maximum density was for Dendrocalamus stocksii (Mes). Water absorption bamboo mat board decreased as thickness increases and was minimum for Dendrocalamus stocksii (Mes). Tensile strength and compressive strength for bamboo mat board increased as thickness increases. For Dendrocalamus stocksii (Mes) maximum tensile strength and maximum compressive strength was 37.83, 43.21 and 48.50 N/mm2and 15.75, 19.21 and 26.30N/mm2 for 9, 12 and 16 mm thickness, respectively.Keywords
