Unmodified fly ash was classified as a medium\-grained calciferous material. The basic components of ash were silicates \(33.28% of SiO2\) and calcium compounds \(31.26% of CaO\). It has a low heavy metal content falling within a range characteristic of coal ash and meeting soil quality standard requirements."]
