Abstract:
In the present paper, the effect of ring fibres in concrete is analyzed and discussed. The effect of ring fibres in both fresh and hardened phase is studied. In the fresh state, the loss of workability is studied by means of reduced slump and slump-flow with increasing fibre volume. In the hardened state, the ring fibre reinforced concrete’s tensile strength and flexural tensile strength are investigated with different ring fibre content. The results from the experimental work show that adding ring fibres to the concrete does not reduce the workability more than acceptable, and that the hardened properties are improved.
