粉煤灰是燃煤电厂排出的主要固体废物,属于工业废渣之一,如不处理,会产生扬尘环境污染。水泥粉煤灰碎石桩(CFG桩)复合地基是由水泥、粉煤灰、碎石等混合料加水拌合在土中灌注形成竖向增强体的复合地基。粉煤灰是其主要的原料之一,随着水泥粉煤灰碎石桩(CFG桩)复合地基在地基处理中的广泛应用,这样一来,不仅使得粉煤灰进行了废物利用,而且相对减少了粉煤灰对环境的污染和对人体的伤害。粉煤灰污染与利用 Fly ash is the main solid waste discharged from coal-fired power plants and belongs to one of the industrial waste residues. If not treated, it will cause dust pollution. Cement-flyash gravel pile (CFG pile) composite foundation is composed of cement, fly ash, gravel and other mixture of water mixing in the soil to form a vertical reinforced composite foundation. Fly ash is one of the main raw materials. With the wide application of CFG pile composite foundation in foundation treatment, not only the utilization of waste fly ash is made, but also the relative Reduce the environmental pollution of fly ash and harm to the human body.
