摘要

煤是燃煤发电厂常用的燃料,发电厂生产煤粉煤灰和煤底灰(煤FABA)作为副产品。印尼的最新法规将煤的FABA分类改为无毒废物,这为其利用开辟了可能性。本文分析了苏拉亚煤电厂的煤FABA作为混凝土材料的潜力及其对环境的影响。为了确定煤的FABA潜力,本文使用的方法有坍落度试验、抗压强度试验、弯曲强度试验和碳足迹计算。研究表明,含煤FABA的混凝土混合料坍落度较低,抗压强度较低,抗弯强度普遍较低。此外,碳足迹计算结果表明,含煤FABA的混凝土混合物比传统混凝土具有更低的CO2排放量。结果表明,掺煤FABA的混凝土可以作为非结构混凝土使用。

On the Performance Analysis and Environmental Impact of Concrete with Coal Fly Ash and Bottom Ash
Coal is a commonly used fuel by coal power plants that produce coal fly ash and coal bottom ash (coal FABA) as byproducts. The latest regulation in Indonesia changes coal FABA classification to non-toxic waste, which opens up its utilization possibility. This paper analyses the coal FABA potential from Suralaya Coal Power Plant as concrete material and its environmental impact. To determine coal FABA potential, the methods used in this paper are slump test, compressive strength test, flexural strength test, and carbon footprint calculation. This paper shows that concrete mixture with coal FABA content has a lower slump value, lower compressive strength, and generally lower flexural strength. Furthermore, the carbon footprint calculation result shows that concrete mixture with coal FABA content has lower CO2 emissions than conventional concrete. Finally, the result shows that concrete with coal FABA could be used as non-structural concrete.
