Title: The impact of the amount and length of fibrillated polypropylene fibres on the properties of HPC exposed to high temperature
Author(s): I. Hager, T. Tracz
Appears on pages(s): 57-68
Keywords: high performance concretes, high temperature, spalling, PP fibres, gas permeability
Abstract:This paper presents the results of research on high performance concretes (HPC) modified by the
addition of polypropylene fibres (PP fibres). The scope of the research was the measurement of the
residual transport properties of heated and recooled concretes: gas permeability and surface water
absorption. Seven types of concrete modified with fibrillated PP fibres were tested. Three lengths: 6,
12 and 19 mm and three amounts of fibres: 0, 0.9 and 1.8 kg/m3 were used. The research programme
was designed to determine which length of fibres, used in which minimum amount, will, after the
fibres melt, permit the development of a connected network and pathway for gases and liquids.\
