Abstract This study investigated the mechanical properties and microstructural characteristics of fiberboard composite produced by naturally-bonded Malaysian bamboo fiber (Bambusa vulgaris). The components that obtained through soda pulping of bamboo culms such as fiber and black liquor, were used for the preparation of high-density fibreboard composite at two target densities of 850 and 950 kg/m³. The bamboo fiberboard composite (BFC) were then produced at 200°C and two pressing parameters of 125 and 175 s/mm. The mechanical properties, e.g., flexural strength and internal bonding (IB) of BFC samples were evaluated according to BS EN 310: 1993 and BS EN 319: 1993, respectively. It was… More > Graphic Abstract

Abstract In the present study, in order to investigate the effects of fly ash on the structural evolution and strength damage mechanism of Pisha-sandstone cement soil, unconfined compressive strength tests of Pisha-sandstone cement soil with different fly ash content levels and various ages were carried out. The apparent morphology, microstructures, and chemical compositions of the samples were observed and analyzed using ultra-depth three-dimensional microscopy, scanning electron microscopy, and XRD methods. The results revealed that the unconfined compressive strength levels of Pisha-sandstone cement soil samples displayed increasing trends with the increases in fly ash content and age. For example, when the fly… More > Graphic Abstract

Abstract Fire safety of light gauge cold-formed steel frame (LSF) stud wall systems is critical to the building design as their use has become increasingly popular in commercial, industrial and residential construction throughout Australia. These walls are made of a cold-formed steel frame lined with multiple plasterboards (up to 4 on each side) and are often used as load-bearing walls. Currently there is limited design information on LSF load bearing walls for use by Australian engineers and designers. Hence LSF wall manufacturers depend on full scale fire tests using the standard fire curve based on ISO834 and AS1530.4 to determine the… More >
