Abstract

The rebound number, its relationship to fundamental frequency and correlations with compressive strength and erosion - abrasion resistance are discussed. Nine mix proportions were used. The w/c ratios were varied from 0.30 to 0.65. The volumetric percentage of hooked steel fibres was varied from 0.25 to 2.0 vol.% at the w/c of 0.30; at the others the quantity of fibres was constant. In addition, mixes without fibres were made at each w/c.

The rebound number and the fundamental frequency are decreased by an increase of steel fibre content. The rebound number correlates with erosion - abrasion resistance. It does not correlate with compressive strength of concretes with constant w/c and different contents of fibres.
