摘要

This paper presents the results of the examinations of the abrasive resistance of the eight types of high strength fibre-reinforced concrete (HSFRC) with compressive strength of 80-100MPa. There were two methods of designation of the abrasive resistance: ASTM C 944 and ASTM C 1138. The mixes contained two types of steel fibre: 30 and 50-mm in length and aspect ratios of 60 and 50 and a polypropylene fibre as a reinforcement. All the mixes were made with Portland cement CEM I 42.5R, basalt aggregate with added superplasticizers and silica fume (w/cm ratio fixed at 0.25 to 0.27). There is a comparison of the results of these examinations with the results for two high strength concretes (HSC) without fibre reinforcement. The presented model of the kinetics of abrasive wear of HSFRC is compared to the according model made for ordinary concretes.

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
