Bio-aggregate Based Building Materials exposed to Fire

Written by esba

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 are highlighted in this chapter. Various results of fire reaction tests 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 tests must be performed on walls or parts of a building to give a more realistic overview of the behaviour of building structures exposed to standard fire. In some of the 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.

The European Straw Building Association is an independent European association, devoid of any profit making motive. The object of the Association is to promote and develop the use of straw, as a sustainable way of building in all the senses of the term “sustainable”: renewable, ecological, healthy, energy and climate efficient, social and economic.
The Association is a federation composed of organisations and people particularly concerned with the use of straw in buildings.
