Abstract The feasibility of a sustainable non-autoclaved cellular concrete, based on flax vegetable co-products, for the production of usable specimen in the lightweight construction field, has been investigated experimentally. The produced specimen, containing various volume ratios of flax particles with respect to preformulatd Tradical PF70 lime binder of 0, 1, and 2, were lightened by creating a porous structure in the matrix through the addition of 0.3% wt. Aluminium powder (able to react with calcium hydroxide from the binder and result in microscopic air-bubbles). Fresh and hardened specimen properties, including hydration, fresh density, porosity, hardened density, compressive and flexural strengths, toughness… More >

Abstract Construction Industry operates relying on various key economic indicators. One of these indicators is material prices. On the other hand, cost is a key concern in all operations of the construction industry. In the uncertain conditions, reliable cost forecasts become an important source of information. Material cost is one of the key components of the overall cost of construction. In addition, cost overrun is a common problem in the construction industry, where nine out of ten construction projects face cost overrun. In order to carry out a successful cost management strategy and prevent cost overruns, it is very important to… More >

Abstract Omni Processors (OP) are machines which use sludge as a fuel to generate electricity and clean water, but create ash at the same time. In the present study, fly ash and bottom ash are investigated as materials for potential reuse in the construction field. First, the granular size, density and Blaine finesse are determined. Then, the chemical composition and microstructure are obtained by means of X-ray fluorescence and Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS), respectively. Finally, ashes reactivity is determined by two chemical methods (modified Chapelle test, bound water content R3) and a mechanical method (pozzolanic activity index). The characterization… More >

Abstract The demand for high-performance, yet eco-friendly materials is increasing on all scales from small applications in the car industry, instrument or furniture manufacturing to greater dimensions like floorings, balcony furnishings and even construction. Wood offers a good choice on all of these scales and can be modified and improved in many different ways. In this study, two common European hardwood species, Beech (Fagus sylvatica L.) and Ash (Fraxinus excelsior L.) were densified in radial direction by thermo-mechanical treatment and the densified product was investigated in an extensive characterisation series to determine all relevant mechanical properties. Compression in the three main… More >

Abstract Wood and wood-based composite materials have gained increasing attention in the sustainable building industry because of their renewability and environmental friendliness. Oriented oblique strand lumber (Eucalyptus Strand Wood, ESWood), which is manufactured from fast-growing small diameter eucalyptus wood (Eucalyptus urophylla × E. grandis), is introduced in this paper. Small clear specimen tests were conducted to determine the mechanical properties of ESWood material while full-scale component tests were performed to observe the structural performance of ESWood beams. A comparison of mechanical properties of ESWood with other wood/bamboo-based materials is then reported. From the results presented herein, it appears that the strength… More >
