| 摘要 |
The present invention relates to an eco-friendly cementless red clay concrete binding material composition in which a binding material containing blast furnace slag, fluidized-bed boiler fly ash, and sodium silicofluoride is used so that a red clay material lacking hardening characteristics can be provided with hardening characteristics. In the eco-friendly cementless red clay concrete binding material, blast furnace slag, fluidized-bed boiler fly ash, and sodium silicofluoride are configured to have an appropriate mixing ratio, instead of cement discharging carbon dioxide in quantity, for production of red clay concrete having a compression strength of 25 to 65 MPa which has excellent workability and allows curing at room temperature. The present invention contains 65 to 80 wt% of blast furnace slag, 17 to 27 wt% of fluidized-bed boiler fly ash, and 3 to 8 wt% of sodium silicofluoride in order to achieve the above-described object. |
