| The objective of this study was to improve the recycling rate of coal ash fly, industrial waste. This study was conducted to analyze the physico-chemical properties of ""CellCaSi"" and clarify the effects on the growth of Kentucky bluegrass(Poa pratensis L.) and creeping bentgrass(Agrostis paulstris Huds ""Penncross"") and the chemical properties of soil, which was cellular calcium silicate reproduced by coal ash fly. A field assay was carried out in Young-Pyong Golf Course. The results were as follows. 1. The main chemical composition of CellCaSi was $SiO_2$(45~55%) and CaO(25~35), which was 70~90% of total weight. CellCaSi showed pH 8~9. Bulk density of CellCaSi was 0.35~0.45g/㎤. Water content of CellCaSi was 52.5~67.5%. 2. In the applied plots, leaf width, grass density per $1 extrm{cm}^2$, rhizome number and length per plant, and root number per plant of Kentucky bluegrass(Poa pratensis L.) and creeping bentgrass(Agrostis paulstris Huds ""Penncross"") showed increasing tendency compared with the control. The application of CellCaSi increased the growth of turfgrasses. Their visual quality on hardness, grass shoot density per $1 extrm{cm}^2$ and root growth was very good. And, their visual quality on rhizome growth was good. 3. After the application of CellCaSi, pH, CEC, Ex-cation of the applied soil showed increasing tendency with the little range, $SiO_2$content increasing tendency considerably, and organic matter content decreasing tendency compared with the control.ncy compared with the control. |
