摘要

利用轻质油棕壳生产高强度轻质可持续材料,使许多研究人员将其作为结构混凝土商业化。然而,油棕壳混凝土抗拉强度低,阻碍了其发展。本研究旨在通过添加高达3%体积的钢纤维来提高OPSC的机械性能和弯曲性能,以生产油棕壳纤维增强混凝土(OPSFRC)。实验结果表明,钢纤维的加入显著提高了OPSFRC的力学性能。添加3%钢纤维的OPSFRC混合料的抗压强度、劈裂抗拉强度和抗弯强度最高,分别为55、11.0和18.5 MPa。此外,对添加3%钢纤维的OPSFRC梁进行了抗弯梁试验,结果表明,当钢纤维配筋达到3%时,OPSFRC梁的弯矩承载力和抗裂性能均有显著提高,但延性有所降低。

High strength oil palm shell concrete beams reinforced with steel fibres
The utilization of lightweight oil palm shell to produce high strength lightweight sustainable material has led many researchers towards its commercialization as structural concrete. However, the low tensile strength of Oil Palm Shell Concrete (OPSC) has hindered its development. This study aims to enhance the mechanical properties and flexural behaviours of OPSC by the addition of steel fibres of up to 3% by volume, to produce oil palm shell fibre-reinforced concrete (OPSFRC). The experimental results showed that the steel fibres significantly enhanced the mechanical properties of OPSFRC. The highest compressive strength, splitting tensile and flexural strengths of 55, 11.0 and 18.5 MPa, respectively, were achieved in the OPSFRC mix reinforced with 3% steel fibres. In addition, the flexural beam testing on OPSFRC beams with 3% steel fibres showed that the steel fibre reinforcement up to 3% produced notable increments in the moment capacity and crack resistance of OPSFRC beams, but accompanied by reduction in the ductility.
