PROBLEM TO BE SOLVED: To contribute to prevention of environmental pollution by coating a beam or column of a building with a fireproofing material predominantly composed of waste of coal ash discharged from a thermal electric power plant.SOLUTION: Clinker ash, which is waste of coal ash discharged from a thermal electric power plant, and diatomaceous earth are mixed together under adhesive spray. Additionally, this mixture contains cement and an adjuvant to form a fire resistive covering material 1. The fire resistive covering material 1 coats a beam 3 or column 4 of a building 2 to improve fire resistance and strength, which are required for the building 2. |
