Abstract [en]

This paper addresses the flexural behaviour of medium-strength, and high-performance concrete (HPC) reinforced with macro fibres made of basalt fibre reinforced polymer (BFRP) with the intended use for marine applications. Mechanical properties of the fibre concrete were studied through an experimental programme consisting of 18 beam specimens and 45-cylinder samples. In this study two types of concrete were used; medium-strength and high-performance concrete with the compressive strength of approximately 60-75 MPa and 90-105 MPa, respectively. The aspect-ratio of the used fibres were 65 and 83, respectively. The experimental results show that the post-cracking properties of macro basalt fibre concrete is a function of the fibre volume content.

2017 (English)In: Nordic Concrete Research, ISSN 0800-6377, Vol. 57, no 2, p. 89-102Article in journal (Refereed) Published
Abstract [en]

The use of Macro Basalt Fibre Concrete (MBFC) for structural purposes is increasing in the Norwegian market. However, findings on properties related to fire spalling are scarce in the literature. Motivated by this, the authors present the results of a pilot experimental study on fire spalling properties of two types of basalt fibre concrete. The study results show that basalt fibres cannot prevent high-performance concrete (HPC) from fire spalling. Nonetheless, the comparison of the average spalling values indicates that use of basalt fibres probably does not increase the spalling propensity of the tested materials.
