“…Industrial wastes, such as blast furnace slag, fly ash and silica fume are being used as supplementary cement replacement materials. In addition to these, agricultural wastes such as rice husk ash, wheat straw ash, and sugarcane bagasse ash are also being used as pozzolanic materials and hazel nutshell used as cement replacement material [2][3][4][5][6][7][8][9][10][11]. When pozzolanic materials are added to cement, the silica (SiO 2 ) present in these materials reacts with free lime released during the hydration of cement and forms additional calcium silicate hydrate (CSH) as new hydration products [12], which improve the mechanical properties of concrete formulation.…”

“…Cement-bonded composites are made from the strands, particles or fibres of light-weight agro-forestry residues such as sawdust, tea waste, oil palm shells, hazelnut shell, and cork waste, among others (Bentur and Aekers, 1989;Demirbas and Aslan, 1998;Wolf and Gjinolli, 1999;Basrri et al, 1999;Karade et al, 2002;Karade, 2003). The matrix is usually cement paste or mortar and the fibre content can be as high as 10% by mass of cement (Mallari et al, 1999;Baski et al, 2003).…”

In this study, the effects of partial replacement of ordinary Portland cement with natural polymers on selected physical and mechanical properties of cement-bonded rattan composites was investigated. Fibrous particles of Laccosperma secundiflorum rattan cane species were mixed with cement mortar at two levels, that is, 2.5 and 5.0%. For experimentation, Portland cement was partially replaced at four levels, first with Cissus populnea gum (0, 10, 20, and 30%) and then natural rubber latex (0, 2.5, 5.0, and 10%). All test specimens were prepared and tested in accordance with ISO 8335 standard. Results obtained showed that the moisture content, density, water absorption, thickness, and bending strength of the composites met the minimum standard requirements, except for samples produced using 30% C. populnea and 5% rattan fibre that fell short of the 9 N/mm 2 minimum bending strength requirement. Partial replacement of cement with the two polymers resulted in a general increase in density. Analyses of variance showed that C. populnea gum had a significant effect (p<5%) on water absorption after 24 h of immersion, while natural rubber latex and C. populnea gum had significant effects on thickness swelling at 2 and 24 h of immersion, respectively. Also, C. populnea gum and rattan fibre contents had significant effects on the bending strength of the composites. It was concluded that Portland cement could be partially replaced with up to 20% of C. populnea gum or up to 2.5% of rubber latex in rattancement composite manufacture without adverse effects on the basic composite properties tested.

“…Numerous researches on cement composites employing various forms of wood product wastes as aggregates, such as ground hazelnut shell, wood sawdust, and tea waste, had been experimentally carried out to determine their mechanical properties. [1] Load-deflection characteristics on composites of wood particles from construction wastes bonded with cement indicate that most composites exhibited closely an elastoplastic behavior. [2] Rice straw-wood particle composite boards had been developed and produced as commercial insulation boards.…”

The aim of this study is to investigate the potential use of Parawood particle waste (PWP) and cement to produce PWP cement composites for use as construction and decorative boards. Strength effects of the PWP-cement composites prepared, with respect to PWP/cement ratio and the type and amount of admixtures, were studied and discussed. Mixture M0-35-1 emerged as a suitable compromise between good practical strength and desirable high usage of PWP. For durability study, wet/dry accelerated, and natural aging, were imposed on the board prior to flexural testing. Mechanical properties were evaluated in terms of the equivalent modulus of rupture, equivalent modulus of elasticity, and toughness index. Significant deterioration of properties was found after 100 cycles of accelerated wet-dry aging, equivalent to 609 days under natural exposure. Poor durability infers that the created board needs to be further engineered to withstand rigorous outdoor applications.
