Spalling of concrete – influence of porosity and specimen size and its critical factors regarding safety
VSH Hagerbach Test Gallery Ltd., 8893 Flums, Switzerland
The influence of porosity and of the specimen geometry and its stiffness on the behaviour of spalling in an event of fire is investigated. Fire resistance is heavily depending on the w/c and air void content values. Thinner specimen with possibility of elongation and higher air void content is generating better laboratory testing results in case of fire resistance.
