Lightweight Concrete with Different Content of PP Fibers Exposed to High Temperature

Abstract:

Mechanical resistance of building materials exposed to high temperatures, e.g. fire loading or explosion damage, is one of parameters that determine the safety of structures. The residual strengths determine load-bearing capacity of construction after exposure of extreme temperatures. Mechanical properties of materials exposed to high temperature (400°C and more) are primarily tested and determined at ambient temperature testing mode. It means, that the sample is exposed to high temperature loading and after cooling to the nature temperature T₀ = 20°C are tested in common used testing machines. These residual strengths are a valuable foundation for an assessment of the structure exposed to a temperature load. The paper presents the test results of mechanical properties at hot state compared to the test results at ambient temperature for four type of lightweight concretes exposed to several temperature levels T_max = 200°C, 400°C, 600°C, 800°C and T_max = 1 000°C.
