Title

Effect of wollastonite nano gel on physical, mechanical and morphological properties of bagasse-cement composites

Pages

  397-408

Abstract

 In this study, the effect of wollasttonite nano gel on physical, mechanical and morphological properties of composites made of Bagasse and cement is investigated. The mixing ratio of Bagasse as lignocellulosic material with Portland cement at three levels (15: 85, 25: 75 and 35: 65%) and wollastonite nano gel at three levels of 0, 3 and 7% were considered as the variables. The cake density of all boards were 1. 1 g/cm 3 and calcium chloride at 5% (based on weight of the cement) for all treatments were considered as constant factors. Mechanical and physical properties of the specimens including modulus of rupture, modulus of elasticity, internal bonding, thickness swelling after 2 and 24 hours immersion in water and density of boards according to DIN-EN634 and fire resistance (weight loss percentage) according to standard ISO-11925 were measured. In this study, the hydration temperature of a mixture of cement, Bagasse and nano-wollastonite was measured using a thermocouple and flux. Microscopic images (SEM) of samples were prepared to investigate the morphological properties of composites and the distribution. The results showed that by increasing the amount of nano-wollastonite, the percentage weight loss of boards decreased, the heat of hydration and the physical and mechanical properties improved. The modulus of rupture, modulus of elasticity, and internal bonding of boards decreased with increasing Bagasse content and the maximum value was obtained using 15% Bagasse. The results also showed that with increasing Bagasse content in boards, there was a significant increase in thickness swelling of boards. Microscopic imaging (SEM) showed that the optimum level of nano-wollastonite can fill the porosity of the boards and create a uniform structure and thus improve the properties of the boards.
