摘要

研究了含有发泡聚苯乙烯珠（EPS）和棕榈油燃料灰（POFA）的钢筋混凝土（RC）梁的荷载-挠度行为，其中发泡聚苯乙烯珠（EPS）和棕榈油燃料灰（POFA）作为沙子和水泥的替代物，比例介于 10%和 30%之间。RC 梁的尺寸为 1000×150×150 毫米，简单支撑，间距为 750 毫米。不含发泡聚苯乙烯的 POFA 含量为 10%，其抗压强度比普通混凝土略高 0.26%。使用 EPS 和 POFA 的 RC 梁的极限荷载和抗弯性能呈下降趋势。所有梁的极限荷载都超过了设计值。RC 梁的裂缝可归类为垂直弯曲裂缝，根据裂缝角度，部分裂缝可归类为剪切裂缝。当所有试样中 EPS 和 POFA 的比例增加到 20% 以上时，裂缝开始转变为剪切裂缝。

The behaviour of Reinforced Concrete Beams by Using Expanded Polystyrene Beads and Palm Oil Fuel Ash as Replacement Materials

The Reinforced Concrete (RC) beams containing Expanded Polystyrene Beads (EPS) and Palm Oil Fuel Ash (POFA) as sand and cement replacement with a percentage between 10% and 30% were studied in terms of load-deflection behaviour. RC beam’s size was 1000×150×150 mm and simply supported at spaced 750 mm apart. The 10% of POFA without EPS shows a slight increase which is 0.26% higher than normal concrete in compressive strength. The ultimate load and flexural performance of RC beams with EPS and POFA exhibited a decreasing trend. All beams’ ultimate load exceeds the design value. The cracks of the RC beam may be classified as vertical flexural cracks, and some of the cracks can be classified as shear cracks based on the crack angle. As the percentage of EPS and POFA increases above 20% for all specimens, cracking starts to change to shear cracking.
