“…This means that the fibres must still contain most of their lignin, plus some other normally extractable materials. It has been shown by Coutts and Campbell (1979) that surface treatment with suitable reagents can increase the strength properties of composites.…”

“…Fibres may also bridge a crack reducing the amount a crack may open. This is the behaviour that confers post yield ductility to the composite [ (Campbell and Coutts (1980); Couttsand Campbell (1979)|. The deflection of cracks and the subsequent pullout of the fibres increases the fracture surface area and hence the energy required to fracture the composite.…”

“…The specimens examined were selected from flexural test specimens used in the previous studies [Campbell and Coutts (1980); Coutts and Campbell (1979)). These specimens had been prepared by trowelling into moulds a slurry consisting of l part (w/w) air dry woodfibre pulp, 40 parts (w/w) Type A ordinary Portland cement and 16 parts (w/w) water.…”

“…The cement matrix composites reported in this study are reinforced with cellulosic fibres derived from Pinus radiata wood chips. The mechanical properties of these composites have been reported by Campbell and Coutts (1980) and Coutts and Campbell (1979). The aim of this paper is to visually clarify the reinforcement mechanism and fracture phenomena associated with such composites.…”

Study of Wood Fibre Reinforced Cement Composites SummaryScanning electron microscopy has been used to investigate fracture surfaces of wood fibre reinforced composites. Fibres may break at the fracture interface, or pull out from the matrix, depending on the treatment at the time of composite formation. Raster-elektronenmikroskopische Untersuchung an Holzfaser-verstärkten Zement-VerbundkörpernZusammenfassung Mit Hilfe der REM wurden die Bruchflächen von Holzfaser-verstärkten Zement-Verbundkörpern untersucht. Die Fasern können an der Bruchgrenzfläche reißen, oder sie werden aus dem Verbund herausgerissen, jeweils in Abhängigkeit von der Behandlung bei der Werkstoffbildung.

“…Cellulosic fibers contribute to the development of high-quality fiber-reinforced cement composites [1][2][3][4]. Fiber-reinforced cement (FC) is used in a wide range of applications from building facade cladding systems to advertising and promotional and decorative applications, and it is becoming increasingly common throughout the day.…”

is present study was carried out to check the feasibility of different cellulose fibers obtained from cropped virgin cellulose, blenched eucalyptus, and araucaria pulps through different new environmentally friendly curing processes for fiber-cement production. e aim is to introduce the different sources of cellulose fibers with lower cost to produce the "fiber-cement without autoclave" (FCWA). e slurries used in the experiments contain approximately 8% wt. of cellulose. e influence of the waste marble powder addition to the cement mixture was also studied. e physical and mechanical properties of the products which were prepared with this method under different curing conditions were investigated. e mechanical properties of eucalyptus cellulose appear to offer the best combination, especially after longer air-cure cycles. e results showed that the production of FCWA is very economical by using waste marble powders. And moreover, two new types of cellulose fibers (eucalyptus and araucaria celluloses; EuC and ArC, resp.), which provide a better density and packing in the fiber-cement leading to better modulus of rupture (MOR) and modulus of elasticity (MOE) values as virgin cellulose (ViC), are very usable for production of the fiber-cement in industrial scale.
