The palm oil clinkers has a high silica content to use in high strength concrete mixtures as additives. In the study to replace silica fume used fly ash which is made from the palm clinkres and mashing then filtered with a No. #200 sieve. The study used a tested beam with 15 30 220 cm sized with concrete strength design (f’c) 60 MPa and (w/c) is 0.25. The main reinforced used 15.8 mm diameter with yield strength (fy) 446.34 MPa and shear reinforced used 11.9 mm diameter with yield strength (fy) 381.72 MPa. The compressive strength test at 28 days of 3 pieces of control specimens showed average value of 58.77 MPa. The maximum deflection in the middle of reinforced concrete beams is 31,8 mm at the maximum load 260.00 kN. The maximum deflection that happened is bigger than theoretical deflection with with two load points 17,126 mm. While the ductility produced by high quality reinforced concrete blocks with additives of palm oil clinkers is 2.313. Strain that occurs in tensile reinforcement and shear reinforcement under maximum loading conditions is 569,911 μm and 8,967 μm. The palm oil clinkers as a substitute for silica fume in high quality reinforced concrete is effectively used to increase concrete ductility.

棕榈油熟料具有高二氧化硅含量，可在高强度混凝土混合物中用作添加剂。在替代硅灰的研究中，使用了粉煤灰，该粉煤灰由棕榈熟料和捣碎制成，然后用 #200 号筛子过滤。该研究使用了一个尺寸为 15 30 220 厘米、混凝土强度设计 (f'c) 为 60 MPa 且 (w/c) 为 0.25 的测试梁。主钢筋直径为 15.8 mm，屈服强度 (fy) 为 446.34 MPa，抗剪钢筋直径为 11.9 mm，屈服强度 (fy) 为 381.72 MPa。3个对照试件28天抗压强度试验的平均值为58.77 MPa。在最大载荷 260.00 kN 下，钢筋混凝土梁中间的最大挠度为 31.8 mm。发生的最大挠度大于理论挠度，两个负载点为 17,126 毫米。而添加棕榈油熟料的优质钢筋混凝土砌块的延展性为 2.313。在最大载荷条件下，受拉钢筋和抗剪钢筋产生的应变分别为 569,911 μm 和 8,967 μm。棕榈油熟料作为优质钢筋混凝土中硅灰的替代品，可有效提高混凝土的延展性。
