Effect of nano- wollastonite on microscopic, mechanical and physical properties of cement- wood fibers composite.
In this study the possibility of nano- wollastonite usage in three level (0 , 3 and 6 percent per dry weight of cement) and mixture ratios of lingo cellulosic materials to cement in three level 10:90, 20:80 and 30:70 on physical, mechanical and microscopic properties of composite made from kraft fib...

| description | In this study the possibility of nano- wollastonite usage in three level (0 , 3 and 6 percent per dry weight of cement) and mixture ratios of lingo cellulosic materials to cement in three level 10:90, 20:80 and 30:70 on physical, mechanical and microscopic properties of composite made from kraft fibers was investigated. There were three replicatesfor each treatment and 27 experimental boards were manufactured totally. Specimens were prepared according to DIN- EN- 634 standard to measure mechanical and physical properties. Mechanical and physical properties including compression strength, interior bonding (IB), thickness swelling after 2 and 24 hours immersion into the water and density were measured. Micro- structural properties of composites were evaluated by SEM images.The results showed that compression strength , interior bonding and density increased by higher levels of nano- wollastonite content in the boards. By increasing of nano- wollastonite, dimensional stability was significantly improved in comparison to the control boards. SEM images showed the improvement of micro- structural boards by increasing the nano- wollastonite content. |
