This study investigated the influence of coal bottom ash (CBA) on the concrete properties and evaluate the effects of combined exposure of sulphate and chloride conditions on the concrete containing CBA. During concrete mixing, cement was replaced with CBA by 10% of cement weight. Initially, concrete samples were kept in normal water for 28 days. Next, the specimens were moved to a combined solution of 5% sodium sulphate (Na₂SO₄) and 5% sodium chloride (NaCl) solution for a further 28 to 180 days. The experimental findings demonstrated that the concrete containing 10% CBA (M2) gives 12% higher compressive strength than the water cured normal concrete (M1). However, when it was exposed to a solution of 5% Na₂SO₄ and 5% NaCl, gives 0.2% greater compressive strength with reference to M1. The presence of 10% CBA decreases the chloride penetration and drying shrinkage around 33.6% and 29.2% respectively at 180 days. Hence, this study declared 10% CBA as optimum that can be used for future research.

本研究调查了煤底灰 (CBA) 对混凝土性能的影响，并评估了硫酸盐和氯化物条件联合暴露对含 CBA 的混凝土的影响。在混凝土搅拌过程中，水泥用CBA代替水泥重量的10%。最初，混凝土样品在普通水中保存 28 天。接下来，将样品移至 5% 硫酸钠 (Na ₂ SO ₄ ) 和 5% 氯化钠 (NaCl) 溶液的混合溶液中再放置 28 至 180 天。实验结果表明，含有 10% CBA 的混凝土 (M2) 的抗压强度比水养普通混凝土 (M1) 高 12%。_{然而，当它暴露于 5% Na 2} SO ₄溶液中时和 5% NaCl，抗压强度比 M1 高 0.2%。10% CBA 的存在在 180 天时分别将氯化物渗透和干燥收缩率降低了约 33.6% 和 29.2%。因此，本研究宣布 10% CBA 是可用于未来研究的最佳选择。
