摘要
本实验研究的重点是用石灰处理的棕榈仁壳(PKS)和甘蔗甘蔗渣灰(SCBA)分别部分替代粗骨料和普通硅酸盐水泥(OPC)制成混凝土的效果。采用水泥:细骨料:粗骨料的设计配合比为1:1.97:3.71、水灰比恒定为0.5的30级混凝土试验分析。对每批混凝土进行了新拌混凝土和易性、硬化混凝土吸水性等物理试验。在第7天和第28天分别对硬化混凝土立方体(100 mm × 100 mm × 100 mm)和圆柱体(100 mm × 200 mm)进行抗压强度和劈裂抗拉强度等力学试验。本研究的实验结果表明,使用15%石灰处理的PKS和10%的SCBA生产结构混凝土的可能性。
Experimental Investigation of Lime Treated Palm Kernel Shell and Sugarcane Bagasse Ash as Partial Replacement of Coarse Aggregate and Cement Respectively in Concrete
This experimental research is focused on the effect of concrete made by incorporating lime treated Palm Kernel Shell (PKS) & Sugarcane Bagasse Ash (SCBA) as partial replacements of coarse aggregates and Ordinary Portland Cement (OPC) respectively. An experimental analysis for concrete grade 30 with a mix design ratio of 1:1.97:3.71 of cement:fine aggregates:coarse aggregates with a constant water to cement ratio of 0.5, was used. Physical tests such as workability on fresh concrete and water absorption on hardened concrete of each batch were carried out. Mechanical tests like compressive strength and split tensile strength were carried out on hardened concrete cubes (100 mm × 100 mm × 100 mm) and cylinders (100 mm × 200 mm) at 7 and 28 days. The experimental results obtained in this study indicate the possibility of using up 15% of lime treated PKS and 10% of SCBA for production of structural concrete.
