In this paper, we focused on a new decorative light density board with a new fiber unit-- micron wood flake, which were large size in length and a very small size in thickness. With these flakes, we processed the light density board in the laboratory, Cunninghamia lanceolata abounded in Fujian Province, Paulownia tomentosa from Anhui Province, L.gemelini Rupr., and Betulaceae abounded in Northeast of China were selected as raw materials, and modified UF as resin. Then several single factor experiments were conducted to discuss the effects of the factors on the physical and mechanical properties of the board, such as board density, resin content, and species of trees as well. The results showed that the density and resin content had significant effects on the mechanical properties of the board. The physical and mechanical properties of the samples, density ranged from 0.3 to 0.5g/cm3, reached Japanese Light Particleboard Standard JISA5908, and the thermal conduction of the board processed with the four species tree were just like solid wood.

Oriented strand board (OSB) is generally used for sheathing in residential walls, floors, and roofs. Because of its low pricing and utilisation of tiny diameter logs from fast-growing trees and thinning logs as raw materials, OSB is anticipated to gain popularity. In chapter, board properties of OSB using smaller strand size of Leucaena leucocephala as core layer had been studied. Small strand size of S3 (length = 75 mm, width = 3.2 to 6.3 mm) was located in the middle layer of the board while bigger strand sizes of S1 (length = 75 mm, width = 12.7 to 19.0 mm) and S2 (length = 75 mm, width = 6.3 to 12.7 mm) were located at the face and back layers. Utilization of smaller strands (S3) in the middle layers may yield boards that have better physical and mechanical properties. Except for MOR in the minor axis, board density and resin content were shown to have a substantial impact on physical and mechanical properties. Except for MOR in the major axis, strand size had little affected on physical and mechanical properties. The effects of board density on mechanical properties were discovered to affect significantly different. With a positive correlation, board density had a significant effect on thickness swelling. Between S1+S3 and S2+S3 strand size, there is no significant effect on bending properties, internal bond strength and thickness swelling. The effect of resin content on bending properties revealed a significant difference of MOR in major axis, as well as MOE values in both major and minor axes. Even when the resin content was as low as 5%, all treatments of OSB passed the general requirement of general purpose OSB.

This study aims to examine the physical and mechanical properties of gypsum board from Acacia mangium Willd wood waste based on gypsum content and wood powder size. This study refers to the JIS A 5417-1992 standard. This research were conducted at Wood Work Shop laboratory for the preparation of raw materials, Wood Technology laboratory Faculty of Forestry for board making and testing the physical properties of gypsum boards, and  PT. Duta Pertiwi Nusantara laboratory to test the mechanical properties of the gypsum board. The material used is  A. mangium W. Wood powder, gypsum flour, water and borax. The study uses Factorial Completely Randomized Design (CRD) with two factors, namely factor A (gypsum content) which consists of gypsum content of 400%, 500% and 600% of the weight of A. mangium W. wood powder, and factors B (wood powder size) consists of 20 mesh passes 40 mesh retained and 40 mesh passes 60 mesh retained.

Great Development

Bricks are widely used as a construction and building material due to its properties. Recent years have seen a great development in new types of inorganic cementitious binders called ‘‘geopolymeric cement’’ around the world. This prompted its use in bricks, which improves the greenness of ordinary bricks. The development of fly ash-based geopolymer lightweight bricks is relatively new in the field of construction materials. This paper reviews the uses of fly ash as a raw materials and addition of foaming agent to the geopolymeric mixture to produce lightweight bricks. The effects on their physical and mechanical properties have been discussed. Most manufactured bricks with incorporation of foaming agent have shown positive effects by producing lightweight bricks, increased porosity and improved the thermal conductivities of fly ash-based geopolymer bricks. However, less of performances in number of cases in terms of mechanical properties were also demonstrated.

The raw materials of the timber industry, especially furniture, are increasingly difficult to obtain in the quantity and quality needed. The development efforts carried out were utilizing Nipah coir waste as a raw material for making particle boards. Particle boards are panel boards made of wood particles or materials containing lignocellulose. Nipah plants contain 27.3% lignin and 36.5% cellulose which has the potential to be used as raw material for particleboard production. This study aims to reveal the physical and mechanical properties of particleboards made from Nipah fruit fibre with adhesive using tapioca flour. The making of particle board is done with a ratio of 90%: 10%, 80%: 20%, 70%: 30%, 60%: 40%, by giving a pressure of 100 kg / cm2. Particle testing is carried out according to the JIS A 5908 standard (2003). From this study, the optimum results were obtained in variations of 60%:40%. The particle physical properties which have an average density value of 1.15 gr / cm3 and an average moisture content of 5.8%. While the mechanical properties obtained by the value of Modulus of Elasticity an average of 21,188.93 kg / cm2. This shows the particle board variations of 60%: 40% produced to meet the JIS A 5908 (2003) standard. Based on the analysis of the quality variations 60%: 40% of particle boards can be recommended as raw materials for interior furniture.
