The mechanical behaviour of normal weight concrete subjected to high t
emperature and biaxial stress is not well understood. The investigatio
n reported is twofold. The strength is studied of unsealed concrete an
d mortar incorporating quarzitic aggregate and bound by Portland cemen
t and subjected to high temperature and biaxial stresses. This involve
s short-term tests and includes the influence of the composition. Addi
tionally a mechanical model is developed for the failure of concrete s
ubjected to these stresses which incorporates not only the main variab
le temperature, but also compositional variables which have a signific
ant influence on the strength of concrete at high temperatures.
