FIREPROOF MORTAR COMPOSITE WITH OLIVINE

摘要

An olivine-containing fireproof mortar composition is provided to prevent oxidation of a joint part and the back of a carbon-containing fireproof brick and have excellent dismantlement of fireproof bricks after use. An olivine-containing fireproof mortar composition is obtained by adding 1-10wt% of a metal powder as an antioxidant and 5-40wt% of oils to a fire-resistant material comprising an olivine powder and amorphous carbon. The fire-resistant material is formed by mixing the olivine powder and amorphous carbon in a ratio of 20:80-70:30. The metal powder is at least one metal powder selected from metal powders comprising Mg or Fe. Further, a particle size of the olivine powder and the amorphous carbon is 1 mm or less.
