Özet
This study aimed to determine the effects of the amount of curing accelerators (Al2(SO4)3 and Na2SiO3) on physical and mechanical properties of cement bonded strandboards made from hybrid poplar strands and to reveal the optimum amount of curing accelerator. For this purpose, Al2(SO4)3 and Na2SiO3 were used at dosages of 3, 5 and 7 % by mass of cement. Al2(SO4)3 /Na2SiO3 ratio was selected as 7/3, in accordance with the literature. Cement/wood ratio and target density were selected as 2.75/1 and 1.2g/cm3, respectively. Physical (thickness swelling, water absorption and density) and mechanical (modulu of rapture, modulus of elasticity, internal bond strength) tests of the strandboards produced were carried out in accordance with the relevant standards. The results showed that the amount of the curing accelerators significantly affected the physical and mechanical properties of cement bonded strandboards. It was determined that the optimal accelator dosage (ratio) for poplar-strand cement boards was 5% ,based on cement weigth.
