“…The use of dispersed reinforcement has its justification, especially where it is necessary to increase the resistance of the concrete to mechanical shocks, increase its resistance to the effects of high temperatures or reduce the risk of its volume changes. However, some authors also consider the addition of dispersed reinforcement to be a suitable tool for increasing the abrasion resistance of the composite [43][44][45]. The theory on which these authors rely is the fact that dispersed microfibers can have a positive effect on the elimination of volume changes of the composite, which are undesirable from the point of view of the subsequent abrasion resistance of the composite.…”

Virtually every concrete structure comes into contact with abrasive effects of flowing media or solids, which have a direct impact on the durability of concrete. An abrasive effect is most pronounced in transport or water management structures, and these structures are often designed for a significantly longer service life (usually 100 years). This research evaluates the influence of the filler component in terms of the type of aggregate and its mineralogical composition on concrete abrasion resistance. As part of the impact of the binder component, several concrete mixtures were produced using the same aggregate and maintaining the same strength class with the addition of different types of active and inert mineral additives. In other parts of the research, the effect of adding fiber reinforcement on the abrasion resistance of concrete was verified. Mutual connections and correlations in different age groups (7, 28 and 90 days) were sought for all obtained results. The abrasion resistance of the composite was monitored by using standard procedures, especially using a Böhm device. It was found that for good abrasion resistance of concrete, it is not necessary to produce concretes with high strength classes using often expensive mineral additives (microsilica) and quality aggregates, but the maturation time of the composite and its microstructure plays an important role.

“…This may be because the abrasive surface is not sufficiently high to wear the steel fibres in the concrete. The higher dosage of fibres results in the degradation of abrasion resistance due to the removal of fibres from the surface of the concrete [47,48]. The results also agree with the significant effect of the Na 2 SiO 3 as an alkaline activator which improves abrasion resistance over that of conventional concrete [49,50].…”

The need to develop sustainable concrete in the civil infrastructure industry increases day by day, resulting in new eco-friendly materials such as geopolymer concrete. Geopolymer concrete is one of the eminent alternatives to conventional concrete for sustainable development by reducing the carbon footprint. Ternary blend geopolymer concrete (TGPC) is a sustainable and environmentally friendly concrete produced with three different source materials to form a binder. The main advantage of TGPC is that it possesses densely packed particles of different shapes and sizes, which results in improved properties. This paper deals with the experimental investigations to evaluate the durability properties of plain and hybrid fibre reinforced TGPC. The durability of concrete is defined as the ability to withstand a safe level of serviceability and different environmental exposure conditions without any significant repair and rehabilitation throughout the service life. Conventional concrete is vulnerable to cracking due to its low tensile and durability properties. The TGPC considered in this work consists of fly ash, GGBS and metakaolin as source materials, selected mainly based on the material’s silica and alumina content, shape, size, and availability. The grade of concrete considered was M55. The main variables considered in this study were the proportions of crimped steel fibres (Vf), viz., 0.5% and 1% and proportions of polypropylene fibres (Vp)viz., 0.1%, 0.15%, 0.20% and 0.25%. The durability properties like water absorption, sorptivity, resistance to marine attack, acid attack, sulphate attack, and abrasion were studied in this investigation. The experimental test results were compared with the requirements provided in the standard/literature and found to be well within limits. The study also indicates that the inclusion of fibres in a hybrid form significantly improves the durability parameters of TGPC. The TGPC with 1% steel fibre and 0.15% polypropylene fibre performs better than the other combination of fibres considered in this experimental investigation.

In this study different mechanical, physical and durability tests were manufactured to investigate the effect of recycled rubber as a partial replacement of fine aggregate by volume on the properties of plain concrete pavements (PC). First step of this paper, the slump, flexural and compression tests are carried out for trial batches to choose airfield PC mix. The second step, the slump, flexural and compression tests are carried out to select the optimum percentage of rubber as a partial replacement of fine aggregate by volume. Afterward, the tests of slump, compression, three point bending of single edge notched beam, splitting, flexural, impact, ultrasonic pulse velocity, Schmidt hammer, electric resistivity, water absorption and abrasion resistance were performed. Results of the experimental study indicated that the addition of rubber recorded significant to slight improvement in the mechanical, some physical and some durability properties of PC. Slight reduction in other properties of PC was observed.
