Application of combined fire protection for steel structures

Abstract

Nowadays, the fire protection of steel and reinforced concrete structures is very important. Steel is sensitive to high temperatures, so its protection needs to be solved. Fire protection of steel structures is a difficult task that can be solved with intumescent paint, mortar, fire protective coating and round concreting. However, fire protection and the construction industry pose an increasing challenge to professionals. The use of a combination of fire protection and thermal insulation materials for the fire protection of building structures can be an interesting and innovative solution. The problem with this solution is that we know very little about the fire protection of this kind of designs. Accordingly, we performed a laboratory experiment on the high temperature resistance of rock wool and fiberglass thermal insulation and plasterboard insulation.
