“…According to Ashori et al (2012), composites produced by the traditional press method with a higher amount of wood particles present a greater number of wood-to-wood bonds, without agglutinant material, thus resulting in lower internal bonding values. In the case of vibro-compacted composites, wood particles were accommodated during vibration, thereby creating Means followed by same capital letter in the same column do not differ statistically by Tukey test (p < 0.05).…”

The aim of this study was to evaluate the influence of particle size and the wood/cement ratio on the physical and mechanical properties of vibro-compacted wood-cement composites. The effects of three different particle sizes (diameter between 1.4-2.36 mm; 2.36-4 mm; and 4-9.56 mm) and wood:cement ratios of 1:2.75, 1:2 and 1:1.5 on wood-cement composites produced with the Amazonia species Swartzia recurva Poepp. and Portland cement type II-Z were analyzed. All evaluated properties were influenced by the particle size used in the mixture; however, the wood:cement ratio only affected the final density of the composite, internal bond and water absorption properties. Composites produced with particles that pass through a 2.36 mm screen but were retained with a 1.4 mm screen showed average values of modulus of rupture and higher modulus of elasticity than composites produced with bigger particles. The use of a 1:2.75 wood:cement ratio resulted in composites with higher density and dimensional stability than composites produced with a lower amount of cement.

“…Papadopoulos et al (2006) suggested that the ideal wood/cement ratio for the MOR property for Oriented Strand Board (OSB) bonded with cement was 1:2 and could even be lower than 1:1.5. Ashori et al (2012) also recommended a wood/cement ratio of 1:1.5 to reach higher average MOR values.…”

“…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). However, there are still some problems extremely restricting the development of wood cement composites, such as high variation in the compatibility of wood species mixed with cement components and the inhibitory effect of some wood species on cement hydration (Matsushita et al 2003).…”

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.
