“…Cement bonded boards, which are a mixture of wood particles with cement, water and some additives (Marteinsson and Gudmundsson, 2018), have been in use for almost a century. Compared to organic bonded wood products, some advantages such as durability, dimensional stability, acoustic and thermal insulation properties and low production cost make them desirable in the construction industry (Lee, 1984;Ramirez-Coretti et al, 1998;Savastano et al, 2003;Okino et al, 2005;Del Menezzi et al, 2007).…”

The effects of fiberglass plaster mesh (FPM) as reinforcement on some physical and mechanical properties of cement bonded particleboard (CBP) were examined. Experimental CBP with and without FPM were manufactured in laboratory conditions using wood particles, cement, tap water and chemical accelerators. Two plies of FPM, manufactured using fiberglass and polyester resin, were laid within the experimental CBP. The target density of CBP was 1300 kg/m3 in the study. Three different types of chemical accelerators (CaCl2, KCl, DARASET ® 580) were used in the experiments. Properties of CBP evaluated include 2- and 24-hour - thickness swelling (TS), 2- and 24-hour - water absorption (WA) and bending stiffness (MOE) and strength (MOR). The results indicate that all the board properties tested were significantly improved by FPM application. The average MOE values of the CBP boards with FPM was two times higher than those of the boards without FPM. Dimensional stability and MOR of the CBP boards were also significantly improved with the use of FPM. FPM can be used to improve inferior properties of the CBP, so as to make it more compatible with other wood based construction materials.

“…The CO2 injection was successful in increasing the initial strength by accelerating the cement curing and bonding the cement and wood. These boards had similar mechanical properties as the boards made via conventional production, and they had a lower cement content (Marteinsson and Gudmundsson 2018). The durability characteristics of composites made of cellulose fiber and cement were studied.…”

Cement wood composites (CWC) are a popular construction material. Lightweight or panel-wise wood-based buildings have a growing market in central Europe. Requirements and regulations on both the global and national level are forcing continuous developments. This paper summarizes the research achievements in improving the hygroscopic and mechanical properties and shortening the manufacturing time of CWC via pre-treatments and additives. In addition, new perspectives on enhancing its fire resistance properties by using fire retardant pre-treatments are discussed. CWC without any pre-treatment is a material within the B-s1, d0 category of fire resistance. Using fire retardants could upgrade it to the category A1 but the fire retardants should not affect the primary properties of CWC. There are a number of potential fire retardants of wood that may be used, such as phosphorus, boron, and magnesium compounds.

“…Wood-cement boards are usually made of wood fibers or particles mixed with cement, water and some additives in order to speed up the bonding process (Marteinsson and Gudmundsson, 2018). They have been already used almost everywhere in the world mainly for roofs, floors and walls (Nazerian et al, 2018).…”

Sunflower stalks (Helianthus annuus) were studied as an alternative raw material for cement bonded particleboard. Experimental cement bonded particleboards measuring 500 mm × 500 mm × 12 mm with nominal density of 1300 kg/m3 were produced using different ratios of sunflower stalk particles with wood. Properties of the cement bonded particleboards evaluated include water absorption, thickness swelling, screw withdrawal strength and bending properties. Results of the study showed that the addition of small amount of sunflower stalks in the production of cement bonded particleboard does not significantly influence the properties tested. Inclusion of more stalks in the mixture significantly decreases mechanical properties and raises thickness swelling and water absorption values of the cement bonded particleboard. Results indicate that boards which include a small amount of sunflower stalks provide properties required by the standards for general purpose-use cement bonded particleboards.
