ABSTRACT:
Reinforced concrete members consisting of a high-strength concrete are subject to explosive spalling. Such spalling can be prevented by the introduction of a capillary system into the concrete of such members, containing substantially linear capillaries having a diameter of at least 3 .mu.m and a length of at least 5 mm. This capillary system can be built during or after the hardening of the concrete without impairing the other desired properties of the concrete or mortar, or it can first be produced under the fire attack. This can be effected with fibers which form the capillaries by dissolution, softening, decomposition, shrinkage or melting and which, due to their shape, i.e. diameter and length, and the incorporated amount, correspond to the desired capillaries.
