장기재령에 따른 판형 & H형강 내화뿜칠재의 내화성능에 관한 실험적 검토

다국어 초록 (Multilingual Abstract)

This study was intended to evaluate the long-term durability and develop the maintenance of fireproof spray coat. To that end, density and adhesion of fireproof spray coat on plate girder and H-beam at normal temperature were measured and the relationship with fire resistance performance was evaluated. The specimen was fabricated by spraying the coat on plate girder and H-beam and remained at normal temperature for 2 years.
As a result of measuring the density of spray coat, the density was rapidly reduced in line with vaporization within 15 days and showed very little change to density since then.
When it comes to adhesion over a long-term period, adhesion of 52.2% of vermiculite material appeared to increase in 2 years, while 44.8% of plaster material showed increased adhesion, indicating higher increase by vermiculite than plaster material. And as a result of reviewing adhesive strength and fire resistance performance, the higher the adhesion, the lower the heating temperature, indicating it's inverse proportion to fire resistance performance.
The test proved that the fire resistance performance of the specimen on plate girder and H-beam became deteriorated over the time and as a result of comparing and reviewing the highest temperature after an 1-hour fire resistance test, spray coat with vermiculite material indicated the temperature 20℃higher on plate girder and the spray coat with plaster material also indicated the temperature range 10℃ higher on plate girder.
