Abrasion resistance of fibre reinforced concrete floors
The inclusion of fibres generally improves the abrasion resistance of concrete floors. Nevertheless, it was found that the most significant improvement was achieved with the initial inclusion of fibre content at 0.51 % by volume. The shape of the steel fibres is not a factor that affects abrasion resistance. However, the type of fibre is significant as there was 75 % abrasion resistance improvement when steel fibres were included into the concrete mix as compared to the equivalent plain concrete but, when the polypropylene fibres were included into the concrete mix, there was an improvement of 86 %. From the experimental results it was further concluded that the length of the steel fibres affects abrasion resistance i.e. the longer the fibre the higher the abrasion depth. Another factor that affects the abrasion resistance of concrete floors is the curing regimes. From the results presented it was observed that the specimens cured by the use of a curing compound are very close to those results of specimens cured by the use of a polythene sheets and both have lower values than air cured specimens. In addition from the experimental investigations it was found that the abrasion resistance and the compressive strength are directly proportional.
