“…This is due to the fact that fibre addition can either favourably or adversely influence abrasion-erosion resistance of concrete depending on their type, size, shape quantity etc. In concrete, there is evidence that fibre addition can either reduce or increase abrasion-erosion resistance by up to 60% and 49% respectively 25,26,29,38,39 while in mortars, adverse effects on abrasion resistance of up to 87% 40 and enhancements of up to 68% 41,42 have been reported. These effects which depend on the fibre types and dosages used can significantly increase the scatter of the data points making comparative analysis difficult.…”

For completeness, underwater test results in which the rock types used in the CA were insufficiently described as either natural gravel 49 , crushed stone 39,52,53 or marginal 54 aggregates were also considered. In the test data where mineralogical descriptions of CA have been provided, these can generally be categorised into basalt 3,19,25,31,47,48,50 , granite 19,26,48,51 , limestone 19,22,26 and dolomite .…”

Review of Concrete Resistance to Abrasion by Waterborne Solids

In the last four decades, numerous investigations have been undertaken on abrasion-erosion of concrete using various test methods. These have suggested existence of different abrasion mechanisms, limitations of existing test methods and inconsistencies on the importance of compressive strength to abrasion resistance of concrete. The objective of this review is to: understand the mechanisms of concrete abrasion-erosion, assess the suitability of existing test methods to simulate field conditions and investigate the relationship between abrasion resistance and compressive strength. It is found that concrete abrasion mechanisms are dependent on both transport modes of abrasive charge and the ratio of coarse aggregate to matrix hardness. The ASTM C1138 (underwater) test method appears to simulate all the critical modes of sediment induced abrasion expected in field conditions and specific energy can be used as a framework to correlate ASTM C1138 test results with field measurements. With the exception of concrete with rubber aggregates, abrasion loss is found to fit a simple power function of its compressive strength, and no significant improvements in abrasion resistance can be gained by using concretes with compressive strengths exceeding 60 MPa (8.70 ksi). Also, the influence of cementitious additives and coarse aggregate properties is only significant at compressive strengths below the optimal value of 60MPa (8.70 ksi).

“…Macro-fibres which have typical diameters from 0.3 to 1.0 mm, and length in the range of 12-65 mm have been shown to improve the post-cracking ductility of concrete, particularly in the case of steel macro-fibres. Investigations on the influence of steel macro-fibres on the abrasion resistance of concrete [1][2][3][4] have yielded inconsistent results. Liu and McDonald [1] and Sharma et al [4] reported reductions in abrasion resistance due to addition of steel fibres while Sonebi and Khayat [2] found the influence of steel fibre on abrasion resistance to be insignificant.…”

Influence of basalt micro-fibres on the abrasion resistance of concrete in hydraulic structures

2021

In hydraulic structures, abrasion resistance can be a significant driver in concrete specification. Basalt micro-fibres represent a potentially sustainable construction product and have been shown to provide various benefits in concrete, however the implications for hydrodynamic abrasion resistance are to date unclear. This paper is the first investigation of its kind to examine the abrasion resistance of basalt fibre-reinforced (BFR) concretes using the ASTM C1138 underwater test method. Towards this, concretes incorporating fibre dosages of 0.5, 1, 1.5 and 3 kg/m3 were tested. The relationships between concrete abrasion and its fundamental mechanical properties are evaluated. For the particular concretes examined, it is found that based on the Shapiro-Wilks tests at 95% confidence, abrasion loss in BFR concretes followed a normal distribution; the use of basalt fibre in contents of up to 3 kg/m3 did not have a significant effect on abrasion resistance, compressive and tensile splitting strengths, as well as modulus of elasticity. It can be concluded that basalt micro-fibre can be used for their other attributes such as controlling bleeding, shrinkage and plastic cracking in concrete hydraulic structures without deleterious effects on abrasion resistance. The regression models proposed to predict concrete abrasion loss from its mechanical properties were found to be only significant at 48 h for compressive strength and 24 h for both tensile splitting strength and modulus of elasticity.
