“…Therefore, it has become a research focus that utilizing as many green materials as possible by adopting the environmental friendly processing methods. The concept that utilizing the waste from other industrial activities as the raw material has already be a significant consensus (Soroushian et al 2004;Qi et al 2006). Nowadays, wood wastes are widely used for manufacturing wood-cement composites (Torkaman et al 2014;Ashori et al 2012).…”

Despite much work on wood-cement composites, effects of wood species on the hydration of cements remain unclear until now. Thus, we herein investigated systematically effects of two typical wood species wastes on the hydration of Portland cement in this work. It was found that adding the poplar flour prominently affects the formation of the calcium silicate hydrate gel (C-S-H gel) delaying the hydration process, while the Chinese fir flour hardly retards the process due to different components. Compared with the neat cement, addition of both wood flours makes it easier to generate the ettringite. Besides, another important hydration product, calcium hydroxide Ca(OH) 2 , requires much longer time to form in the presence of both wood flours during hydration relative to the neat cement, e.g. nearly double time for the poplar-filled cement system. The findings provide useful information for extending the potential application of wood flours waste in cement composites.

“…The use of cement curing accelerators like CaCl 2 , MgCl 2 and CaCO 3 has been helpful in eliminating the need to pre-soak the wood particles [1,22,23]. Other methods that have been used to improve compatibility between wood and cement are fungal treatment of wood [24]; application of blocking layers around wood particles [25]; CO 2 treatment [26,27]; and the addition of pozzolans, such as volcanic ash, fly ash, rice husk ash and condensed silica fume [18,28]. The total amount of water available for bonding also affects the hydration of the cement paste, as too little or too much water in the paste affects the ultimate strength of the composites [17].…”

Phosphate bonded natural fibre composites: a state of the art assessment

Over the last few decades, innovative wood composite products and processes have created markets for new and existing products. Inorganic bonded fibre composites have been developed for high performance applications using conventional cement and concrete. The demands for wood based composites along with increasing economic and environmental concerns on conventional wood products necessitate moving beyond the traditional processing methods to more cost-effective and environmentally friendly approaches. In the wake of the twenty-first century, a fast-setting phosphate binder with a low carbon footprint was developed, which can alternatively be utilized in wood composite development. This paper reviews the recent progress in phosphate bonded composite products, based on published literature from the last two decades. A brief background on Portland cement based natural fibre composites is presented. In addition, the mechanism of the formulation of phosphate binders, the effect of aggregates in the materials and the environmental benefits accruable to such materials are discussed.

Wood-mineral wool hybrid particleboards

et al. 2010

Abstract. The objective of this work was to compound mineral wool with wood particles in the production of particleboards of reduced flammability. Three series of boards with various contents of mineral wool (10, 20, 30 wt%) were successfully manufactured using ureaformaldehyde resin as binder. Thickness swelling, mechanical and thermal properties as well as ignitability of the boards were assessed. It occurred that reduced ignitability is accompanied by a decrease in mechanical performance.
