In sugar industries, the growing amount of sugarcane bagasse ash (SBA), a byproduct released after burning bagasse for producing electricity, is currently causing environmental pollution. The residual ash displays a pozzolanic potential; and hence, it has potential as a cement addictive. This study focuses on enhancing suitability of SBA through incorporating ground blast furnace slag (BFS) in manufacturing self-compacting concretes (SCCs). For this purpose, SBA was processed by burning at 700 °C for 1 h, before being ground to the cement fineness of 4010 cm²/g. SCC mixtures were prepared by changing the proportions of SBA and BFS (i.e., 10%, 20%, and 30%) in blended systems; and their performance was investigated. Test results showed that the presence of amorphous silica was detected for the processed SBA, revealing that the strength activity index was above 80%. The compressive strength of SCC containing SBA (without BFS) could reach 98%–127% of that of the control; combination of SBA and 30% BFS gets a similar strength to the control after 28 d. Regarding durability, the 10%SBA + 30%BFS mix exhibited the lowest risk of corrosion. Moreover, the joint use of SBA and BFS enhanced significantly the SCC’s sulfate resistance. Finally, a hyperbolic formula for interpolating the compressive strength of the SBA-based SCC was proposed and validated with error range estimated within ±10%.

在制糖工业中，甘蔗渣灰（SBA）是燃烧甘蔗渣发电后释放的副产品，目前正在造成环境污染。残余灰分显示出凝硬潜力；因此，它具有作为水泥添加剂的潜力。本研究的重点是通过在制造自密实混凝土 (SCC) 中加入地面高炉矿渣 (BFS) 来提高 SBA 的适用性。为此，SBA 在 700 °C 下燃烧 1 小时，然后研磨至 4010 cm ^{2的水泥细度}/G。通过改变混合体系中 SBA 和 BFS 的比例（即 10%、20% 和 30%）来制备 SCC 混合物；并对其性能进行了调查。测试结果表明，加工后的 SBA 检测到无定形二氧化硅的存在，表明强度活性指数在 80% 以上。含SBA（不含BFS）的SCC抗压强度可达对照的98%~127%；SBA 和 30% BFS 的组合在 28 天后获得了与对照相似的强度。关于耐久性，10%SBA + 30%BFS 混合物的腐蚀风险最低。此外，SBA和BFS的联合使用显着增强了SCC的抗硫酸盐性。最后，提出并验证了用于插值基于 SBA 的 SCC 的抗压强度的双曲线公式，误差范围估计在 ±10% 以内。
