Abrasive Wear Resistance of Concrete in Connection with the Use of Crushed and Mined Aggregate, Active and Non-Active Mineral Additives, and the Use of Fibers in Concrete

Abstract

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.

Analysis of Abrasion Depth and Rates in Concrete

“…WMP ECLIPSE machine was selected for this research work over other devices after examining all the factors. The mechanism of the wearing due to abrasion was modelled for simulating the wearing of the hydraulic structures by the rubble dragged by water (E. Horszczaruk, 2012), , (Bodnárová et al, 2020), (Zhou et al, 2020), (Abid et al, 2020).…”

“…The construction carried out under the water generally uses numerous variable loadings and stun loadings made of steel fibres, as they enhance the mechanical properties like flexural strength of the structure. Moreover, the steel strands prevent the movement and formation of cracks (Abbass, Abid, & Özakça, 2019), (Abid et al, 2020), (Ali, Kadhim, Ayoob, & Abdul Hussein, 2021), (Bodnárová et al, 2020). However, the steel fibers are not capable of preventing resistance to corrosion of the concrete in most of the hydraulic structures.…”

“…Permeability is become to be one of the most valuable properties influencing concrete durability for the reason that numerous concrete degradation mechanisms are a function of the rate of water or solution flow through the concrete, and it controls the rate of entry of moisture that may contain aggressive chemicals and the undertaking of water during the process. The effect of silica fume and ash was studied using different synthetic fibers or metallic fibres (K. Turk & M. Karatas, 2014), (Liu, 2007), (Yen, Hsu, Liu, & Chen, 2007), (Mohebi, Behfarnia, & Shojaei, 2015), (Gesoǧlu, Güneyisi, & Özbay, 2009), (Bodnárová et al, 2020), (Zhou et al, 2020). A fixed ratio of water/cement (w/c) at 0.3 was maintained in line with the general practice of the mix.…”

“…The percentage of absorption by the mixture proportioning of the concretes under test in the Kingdom of Bahrain was set at 1.2%. Therefore, we have carried out the research accepting the limits according to reference (Abid et al, 2020), (Bodnárová et al, 2020), (Ali et al, 2021), (Rahmani et al, 2012). The amount of the polypropylene fibers (kg/m 3 ) was not allowed to exceed 3% in the mixtures.…”

“…Different ages were tested for each casting sample, between the period from 7 to 28 days and 28 to 90 days. It was reported that the period of 7 to 28 days is an optimum period to improve the wear resistance (Abid et al, 2020), (Bodnárová et al, 2020), (Ali et al, 2021), (Rahmani et al, 2012). These experiments and preparation summarise the importance of the protocols of conducting on-site work and study.…”
