Bio-aggregate based building materials exposed to fire

Abstract

This chapter reports the state of the art of several investigations on behaviour of bio-aggregate based building materials exposed to fire. Discrepancies between fire reaction and fire resistance is highlighted in this chapter. Various results of fire reaction test performed on bio based materials are presented. Bio-aggregates are often in Class F while concretes range in class B1. In the case of fire performances, limited tests are performed and reported in the literature. Such test must be performed on wall or part of building to give the more realistic overview of the behaviour of building structure exposed to standard fire. In some of presented case studies, render and plaster play a key role in the fire resistance. EI 90 fire resistance appeared to be accessible with conventional technologies.
