“…A verification test was run with these parameters, and the results showed that the MOE, MOR, and IB were 8.745 GPa, 46.264 MPa, and 0.485 MPa, respectively. These parameters are similar with those from previous studies of OCB composites (Li et al 2003;Song et al 2008;Qi et al 2012;Hou et al 2014).…”

The use of formaldehyde-free, biomass-based composites has gained increasing attention in recent years because of their environmental benefits and superior strength properties. In this study, oriented cotton stalk board (OCB) was fabricated with an environmentally friendly, waterbased konjac glucomannan-chitosan-polyvinyl alcohol (KCP) blend adhesive using hot pressing technology. The effects of pressing parameters on the physical and mechanical properties of oriented cotton stalk board were examined in order to obtain optimal pressing parameters. Interfacial bonding surface was also examined with a scanning electron microscope and a fluorescence microscope. The optimal physical and mechanical properties were obtained at a pressing temperature of 150 °C for 15 min with a target density of 0.8 g/cm 3 during hot pressing. Adhesive content and hot pressing pressure had significant influences on adhesion. Mechanical interlocking was also observed between cotton stalks and the adhesive. OCB with KCP blend adhesive has comparable mechanical properties to that with urea formaldehyde resin or phenolic formaldehyde resin. OCB resinated with KCP blend adhesive is environmental friendly and has potential applications in furniture and interior decoration with less stringent requirements for water resistance.

“…All these properties are good for insulating against heat and sound while the mechanical strength of the gypsum-based composites are still retained. 5,13 The mechanical properties of gypsum are correlated to its total porosity. 7,[12][13][14][15][16] It turns out that the total porosity of gypsum is influenced by the water/hemihydrate ratio 4,[13][14][15][16] and the aging time.…”

We synthesized cellulose/gypsum composites in the presence and absence of sodium alginate and investigated the interaction between the composite components as well as the mechanical properties of the final composites. Four different types of cellulose fiber materials were used: cellulose UFC100, cellulose B400, nanofibrillated cellulose, and Lyocell fiber. For all investigated composites the total amount of admixed cellulose was between 1 and 2 wt%, the amount of admixed sodium alginate was 0.5 wt%. We determined the morphology of the composites and observed that the particle and fiber dimensions of the admixed cellulose affect the mode of gypsum-gypsum interlocking and the total porosity of the composites. This in turn had a substantial influence on the mechanical properties of the final composite materials. The addition of sodium alginate resulted in an increase of ultimate strain values. Composites with Lyocell fiber, a synthetic fiber, also had a high Young's modulus.

“…The need of reducing the carbon foot print associated to cement production drove much research towards the study of by-products to be used as supplementary cementitious materials (SCMs). Many previous researches [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] undertaken obtained valuable results to use the industrial wastes in various forms of concrete production. For instance, the use of waste rubber, glass powder, and rice husk ash in concrete mix or cement mortar has received conscribe attention over the past years.…”

This paper presents the comparison of results i.e., (compressive strength of cement) by the experimental study and Regression model to evaluate the possibility of utilizing the hylam powder as a partial replacement in cement mortar. The remarkable increase in the production of hylam and its disposal in an ecofriendly manner is increasingly becoming a matter of global concern. Hylam powder is a waste produced from hylam sheets at the time of fabrication (Cutting, Making holes and polishing process) is used as a partial replacement in cement. A total 63cement cube were casted and tested for 3,7& 28days of seven mortar mix (i.e. 0%, 3%, 5%, 7%, 10%, 13% & 15% of Hylam powder was replaced by weight of cement). The results show that incorporation of the hylam powder yields to the increase of strength at the age (28 days) in comparison with that of a control mortar.
