The study reports on block shear investigations with bondlines of face-glued laminations and matched solid wood specimens from hardwood glulam (GLT) beams produced industrially eight technically stand volume-wise important species. European hardwoods comprised oak, beech, sweet chestnut ash the tropical species were teak, keruing, melangangai light red meranti. adhesives phenol-resorcinol melamine-urea. When combining all in one sample, a rather strong linear relationship bond strength was...

Theapplication of laminated veneer lumber (LVL) has long been limited to non-structural elements in Malaysia.LVL is commonly fabricated with from low medium density (290 630 kg/m3)softwood or temperate hardwood. The data on the properties LVL made high (567 687 kg/m3)tropical hardwood species very limited. Therefore, this study investigated mechanical Malaysian namely Kasai (Pometiaspp.), Mengkulang (Heritieraspp.) and Kedondong (Canariumspp.). Different variables were studied: i) wood...

For in-situ bonding of pultruded rod into timber structural members, such as in the construction bonded-in connection, strengthening and repair structures, adhesive used must be thixotropic, room temperature cure, environmentally stable friendly applied at without pressure. This study investigates moisture absorption characteristics three adhesives specially formulated for connections where are reinforced with nano- micro-particles denoted CB10TSS (standard adhesive), Albipox (CB10TSS/CTBN)...

The mechanical properties of adhesive materials change over time, especially when they are subjected to long-term loadings. significance this is often overlooked at the design stage. When adhesives a constant load, may deform continuously, depending on temperature, humidity, and cross-link density. This progressive deformation called creep. It imperative that reliable accelerated tests be developed determine time-dependent performance under different environmental conditions. creep behavior...

This paper reports on the investigation of structural behavior wallettes made from wood-wool cement composite panel (WWCP). Initially, a series experimental test were carried out to investigate mechanical properties WWCP namely density, bending (MOR and MOE), compressive strength tensile for two thicknesses (50 mm 100 mm). Then, axial compression capacity was investigated using wallettes. In fabrication wallettes, there are types arrangement considered denoted as W1 W2. For W1, thick used...

Sustainability in construction industry has brought new materials to be used as a wall element building Malaysia. Wood-wool cement composite panel (WWCP) is the wood based product which manufactured from renewable resources, less embodied carbon emission, lightweight, easy process and fabricate available replace eco-friendly such common brick other masonry element. In Malaysia, there are increasing interest using WWCP construction, however structural performance under imposed load...

Bottom Ash is a by-product from coal electrical power plant. It was classified as scheduled waste. About 1000 tonnes/day of produced and create logistic problem to dispose. used sand replacement material produce cement brick grade C5 C10. The effect compressive strength density containing compared river identified discuss in this paper. From results obtained found that highly potential be use production brick. Even though the lower than sand, but properties still satisfied standard...
