Developing Fire Resistant Construction for Tunnel Construction Using Lightweight Aggregate Concrete

Abstract:

The article describes partial results of the research of fire and technical properties of lightweight concrete with regard to the possibility of the application of lightweight concrete in tunnel structure wall lining. The article summarises partial results of individual parts of the project focused on the specification of material properties, execution of temperature analysis of the fire resistance, calculation of structure heat transmission and specification of the thermal response of the material as subject-matter to the research.
