Cement-bondedparticleboardwith a mixtureofwheatstraw and poplar wood Article in Journal of Forestry Research 24(2) · June 2013 with 157 Reads How we measure 'reads'
Accelerated processing techniques involvingcarbonation reactionswere successfully employed to producecement-based board productsincorporatingwheat straw. Comprehensive mechanical, durability and physical tests confirmed the high potential ofcement-bonded strawboardas a versatile building product capable of meeting the requirements in demanding applications.
Arg.), planted in Brazil, were used to manufacture woodcement-bondedparticleboard (CBWP). Boards measuring 450 × 450 × 13 mm were manufactured in a wood/cement/water ratio of 1:4:1, by weight; nominal density of 1.4 g/cm 3 and 4% of additive (CaCl 2 ·H 2 O) using amixtureof each eucalypts species (50%) and the two clones of rubberwood ...
Viroc ®Cement BondedParticle Board. Viroc is a composite material, composed by a compressed and drymixtureof pine wood particles andcement. It combines the flexibility and durability of wood with the strength ofcement, allowing a large range of applications, both indoor and outdoor.
The effect of CO2 injection on initial strength increase and hardening ofcement-fibremixin acement bondedparticle board (CBPB) production was evaluated. Differentcementcontents, formation pressure and types of fibres were considered. The initial strength increase with CO2 injection is so much faster than this caused by conventional hydration that the produced samples do not need ...
Dec 10, 2013· AbstractGypsum-bonded particleboard(GBPB) panels were made from variousmixtures of particlesofbagasse(Saccharum officinarum L.) andwheat straw(Triticum aestivum L.),bondedwith different ratios ofparticle/gypsum. This study examined the feasibility of bagasse andwheat straw particlesin the production of GBPB.
There are around 18 manufacturers worldwide &cement bondedparticle boards are available across the globe. The demand for such boards has continued to remain consistent & high ever since their invention in the 1970s. In the widercementboard category, of whichcement bondedparticle boards are one type, there are about 90 producers worldwide.
Dec 19, 2013· For example, Versaroccement bondedparticle board (produced by the Mayapple Corporation) contains 71% PortlandCement, 19% wood particles, 9% water and 1% bonding agent. CBPB has a typical density of 1250 - 1400kg/m 3 .
Abstract. An inorganic adhesivemixconsisting of MgO, MgCl 2, Na 2 SiO 3, Na 3 PO 4 was used to prepare mineral boundparticleboard(mbPB) without formaldehyde emission and with excellent fire retardant and smoke suppression properties. The mechanical properties, interior microstructure, fire retardancy and smoke suppression behavior of the mbPB was investigated based on scanning …
Cement bonded particleboardis a construction board, the surface of which is smooth andcementgrey coloured. Its main components arecementand fine wood chip fractions. APPLICATION AREAS Thanks to their excellent strength and weather resistant propertiescement bondedparticleboards can be used for covering walls, floors and ceilings in internal and external conditions. …
This study was carried out to explore the possibility of makingcement-bondedwood–wool composite building products using eucalypt (Eucalyptus camaldulensis) and poplar (Populus deltoides).The experimental design consisted of three treatments – ratio of wood–woolmixture, percentage concentration ofcement, and calcium chloride (CaCl 2).The mechanical properties in terms of …

Abstract: Thecement-bondedparticle boards can be used among other also with reconstructions of various types of buildings as a part of final surface treatment. The paper deals with partial results of the research focused on optimisation ofcement-bonded particle board…
All the boards were produced at lignocellulosic material/cementratio of 1:2.75 on a weight to weight basis. Ascementcuring accelerators, Al2(SO4)3 and Na2SiO3 were used at ratios of 1.5% and 3.5%, based oncementweight, respectively. The MOR values ranged from 0.8 to 10.99 MPa and MOE values ranged from 254 to 2979 MPa.
A method and an apparatus is provided for accelerated processing ofcement-bonded particleboardor fiberboard under pressure through the injection of a diluted carbon dioxide gas.

Cement-bonded wood particleboard with a mixtureof eucalypt and rubberwood
Initial particle moisture content was highly significant in the development of physical andmechanical properties of magnesite cement-bonded particleboard. Increasing initial particle moisture content from 0-6% to 60-80% resulted in the reduction ofthe physical and mechanical propertiesof the boards.
