Abstract

Tensile strength and ductility are the most important characteristics of HIGH PERFORMANCE Fibre Reinforced CEMENTITIOUS COMPOSITEs (HPFRCC). In this regard, parameters such as: type of fibre, properties of matrix and characteristics of their interface play the main role in the behavior of HPFRCCs. The effect of straight and hooked steel fibres on the mechanical properties of FRCs has been extensively investigated. However, only limited investigations have been done on the properties of CEMENTITIOUS matrices reinforced with CRIMPED STEEL FIBREs. The aim of this study is to achieve a HPFRCC using CRIMPED STEEL FIBREs. The performed activities in this investigation can be divided into three stages: to achieve a very dense CEMENTITIOUS material to be used as an appropriate matrix, to find the optimum shape of crimped fibre to be compatible with the matrix, and finally to obtain a CEMENTITIOUS COMPOSITE (using the matrix and the fibres found in the previous stages) with high tensile strength and ductility. In the first stage of this study, 140 mixes were cast and tested. A workable mix with the compressive strength of 170 N/mm2 was selected for the following stages. To find an optimum shape of reinforcing fibres, pull-out tests were performed on single crimped fibres with different wave length and amplitude, embedded in the matrix. The length and diameter of fibres were 20 mm and 0.3 mm, respectively. Among the tested shapes of crimped fibres, 2 mm wave length and 0.4 mm wave amplitude were found to be the optimum values. Finally, in the last stage of the study it was found that the addition of 4% (by volume) the crimped fibres to the matrix produces a workable HPFRCC with tensile strength of 24 N/mm2 and fracture energy as high as 9500N/m (i.e. about 160 times larger than that of ordinary concrete).
