“…Furthermore, the values of an internal bond (IB) ranged from 0.26 MPa to 0.95 MPa, and the values of screw withdrawal (SW) ranged from 224.06 N to 571.10 N. There are also boards with the addition of 5% MgCl 2 that fulfill the standard for IB (IB > 0.5 MPa) and SW (SW > 300 N). MOR and MOE values of cement boards from mangium are smaller compared to cement boards from eucalyptus, which respectively have MOR and MOE values of 15 MPa and 7.5 GPa (Lisboa et al, 2018).…”

“…Compared to cement boards made from Eucalyptus grandis wood with a density of 1.2 g/ c 3 and addition of 6% CaCl 2 as catalyst (Lisboa et al, 2018), cement boards made from mangium wood with the addition of 5% MgCl 2 catalyst have relatively similar TS and WA values. The TS value of mangium cement board with 5% MgCl 2 addition (1.02%) is relatively similar compared to the TS value of eucalyptus cement board (1.5%).…”

The quality of the cement board depends on the compatibility between cement and particles from lignocellulosic biomass. The purpose of this study was to determine the compatibility between cement and particles from four tropical wood namely mangium (Acacia mangium Willd), teak (Tectona grandis Linn. F.), gelam (Melaleuca leucadendron (L.), dadap (Erythrina variegata L.), and sago stem (Metroxylon sago Rottb.), and to determine the physical and mechanical properties of the mangium cement board produced by adding magnesium chloride (MgCl 2) as an accelerator. This research was conducted in two steps. The first step consisted of measuring the hydration temperature of a mixture of cement with particles from the four wood species and sago stems by adding magnesium chloride (MgCl 2), with variations of 0%, 2.5%, 5%, and 7.5% based on the cement weight. Two types of mixtures from the first step were then used in the second step, namely the manufacture of cement board. The cement board was made using a weight ratio of mangium particles:cement:water of 1:2.7:1.35. The board is made with a target density of 1.2 g/cm 3. Physical and mechanical testing refers to the ISO 8335-1987 standard. The results of the hydration temperature showed that all of the mixtures were classified into "low inhibition", except for mixture between cement and mangium particles without a catalyst which was included in the classification of "moderate inhibition". While the results of cement board tests indicate that the cement boards made from mangium wood particles with 5% MgCl 2 addition had better properties compared to mangium cement boards without catalysts.

“…The compressive strength of the control OC was about 37.1 MPa. The literature shows a mean compression strength of 37.3 MPa in moulded cement composites made using Portland cement and no wood [ 61 ]. The creation of glue-water-cement explains this result during the first 28 days of concrete setting.…”

Conservation Environments’ Effect on the Compressive Strength Behaviour of Wood–Concrete Composites

This paper addresses the issues in making wood–concrete composites more resilient to environmental conditions and to improve their compressive strength. Tests were carried out on cubic specimens of 10 × 10 × 10 cm3 composed of ordinary concrete with a 2% redwood- and hardwood-chip dosage. Superficial treatments of cement and lime were applied to the wood chips. All specimens were kept for 28 days in the open air and for 12 months in: the open air, drinking water, seawater, and an oven. Consequently, the compressive strength of ordinary concrete is approximately 37.1 MPa. After 365 days of exposure to the open air, drinking water, seawater, and the oven, a resistance loss of 35.84, 36.06, 42.85, and 52.30% were observed, respectively. In all environments investigated, the untreated wood composite concrete’s resistance decreased significantly, while the cement/lime treatment of the wood enhanced them. However, only 15.5 MPa and 14.6 MPa were attained after the first 28 days in the cases of the redwood and the hardwood treated with lime. These findings indicate that the resistance of wood–concrete composites depends on the type of wood used. Treating wood chips with cement is a potential method for making these materials resistant in conservation situations determined by the cement’s chemical composition. The current study has implications for researchers and practitioners for further understanding the impact of these eco-friendly concretes in the construction industry.

“…The trend towards an increase in apparent density with the insertion of 20% quartzite may be due to the lling of empty spaces in the cement-wood panels during cement hydration. Composites with higher bulk densities tend to have higher mechanical properties (Lisboa et al 2020). In addition, a low or medium density of the wood used allows for a greater contact area during the compaction stage, resulting in stronger bonds and increasing the resistance properties of the panels (Castro et al 2019).…”

The incorporation of residues in cement matrices is a viable alternative in obtaining new products for civil construction and a sustainable solution for the disposal of materials discarded by industries. In this context, the objective of the study was to evaluate the potential use of quartzite and particles of Hevea brasiliensis treated with aluminum sulfate [Al2(SO4)3] in the production of cement-wood panels. Quartzite residues and Hevea brasiliensis wood particles were obtained and characterized. The wood particles were mineralized with Al2(SO4)3 at a concentration of 9%. The panels were produced with CPV-ARI Portland cement, calcium chloride (CaCl2) as additive, treated wood particles and addition of quartzite in different proportions (0, 10, 20 and 40%), totaling four treatments. The physical-mechanical and microstructural properties of the panels were determined. The mineralization of the particles contributed to the adherence to the wood-cement. The incorporation of 20% quartzite contributed to the improvement in water absorption and thickness swelling of the panels and in the increase in the modulus of elasticity (MOE) and modulus of rupture (MOR) values. The cement-wood panels were suitable for non-structural and internal use, requiring further studies to evaluate alternative methods of replacing these residues.
