Abstract: 
This study explores the use of rice husk ash (RHA) and manufactured sand (M-sand) as replacements for cement and fine aggregate, respectively, in lightweight oil palm shell concrete (OPSC). In the first stage of this study, the effect of various cement replacement levels, with RHA (5%, 10%, 15%, and 20%) and 100% sand replacement with M-sand and quarry dust (QD), on the compressive strength of OPSC was investigated. The results showed that the highest compressive strength of OPSC of about 51.49 MPa was achieved with the use of 15% RHA and M-sand. In the second stage of the work, the variables of RHA (0 and 15%) and M-sand (0, 50%, and 100%) were used to investigate their combined effects on the mechanical properties of OPSC. It was found that the combination of 15% RHA and 100% M-sand gave the best performance of OPSC in terms of mechanical properties, such as compressive, splitting tensile, flexural strength, and Young’s modulus.

目的:探索稻壳灰和人工砂在轻质油棕壳混凝土中部分替换水泥和细骨料对混凝土力学性能的影响,期望得到力学性能较高的轻质混凝土。
方法:1. 将不同比例的稻壳灰(5%,10%,15%和20%)替换水泥和100%的人工砂或石粉替换沙子,研究它们对混凝土抗压强度的影响;2. 研究不同替换比例的稻壳灰(0和15%)和人工砂(0,50%和100%)对混凝土力学性能的综合影响。
结论:1.在15%的稻壳灰替换水泥和100%人工砂替换沙子的情况下,最大抗压强度为51.49 MPa; 2. 替换比例为15%稻壳灰和100%人工砂的组合表现出最好的力学性能,包括抗压强度、抗拉强度、抗弯强度和杨氏模量。
