“…Liu & Donald [1], Holland [2], Wu, Yen, Liu & Hsu [5] reported water-to-cement ratio as an important factor and recommended to adopt the lowest practical water-cement ratio where abrasion-erosion is of major concern. Liu & Donald [1], Holland [2], Kryzanowski, Mikos, Sustersic & Planinc [6], Papenfus [3] investigated the abrasion erosion resistance using different types of coarse aggregates in concrete composite. The test results indicate that abrasion erosion resistance of concrete increases with the increase in the hardness of coarse aggregates when the water to-cement ratio and compressive strength are kept constants and concluded that the hardest available aggregate should be used in new construction or repair of stilling basins or other hydraulic structures.…”

Hydraulic structures like spillways, glacis, etc. undergoes abrasion-erosion due to impact & cavitation losses due to the flowing water action. To overcome the deterioration of the concrete in such structures, addition of fibers to the concrete can be viable solution as it is known to increase the structural integrity of the concrete. A comparative study of various engineering characteristics using high strength concrete by incorporating steel fibers and micro polypropylene fibers has been carried out. Water/binder ratio of 0.23 has been kept constant for the study. Dosage for steel fibers are kept as 1, 1.25 and 1.5% by volume while for polypropylene fibers were kept as 1, 2 & 3 kg/m3. Engineering properties such compressive strength, flexural strength, toughness, energy absorption, splitting tensile strength, drying shrinkage, abrasion resistance, and water and air permeability of high performance concrete with & without fibers in its fresh & hardened state are investigated in this paper. Based on the study, the steel fibers with 1.5% dosage are found to be more effective in countering the abrasive and repetitive loading which can be more effective in the repairs of spillways and glacis of concrete dams.

“…The main reason that delays the widespread use of polymer concrete in the hydraulic structures construction is its high cost, the lack of acceptable manufacturing technology, and insufficient knowledge of its properties, which differ significantly from those of conventional concrete [2,3]. The main rise in price falls on the cost of a synthetic binder, the most common and cheapest of which is resin -furfural acetone FA monomer.…”

Introduction. Research of polymer concrete properties show that it differs favorably from conventional concrete by such indicators as mechanical strength, resistance to aggressive impact of various environments, water resistance, abrasion resistance, water-repellency and frost resistance. Currently, it is possible to obtain polymer concrete with characteristic and chemical properties -specified density, strength, deformability, ductility, and corrosion resistance. Methods and materials. The research is carried out by comparing laboratory tests of polymer concrete based on furfural binder. Furfural has a high reactivity and can form resin compounds with many chemicals. Diphenylamine was added to furfural in different proportions. Benzenesulfonic acid, sulfuric acid and their mixture at a ratio -1:1 by weight were used as hardeners. Crushed sand or ground andesite based on nanostructured microfiller served as aggregate for various compositions of polymer solutions. The polymer concrete strength, chemical resistance, lasting properties, water resistance, abrasion resistance, metal adhesion were tested during the research. Structural changes in properties were studied by the electron microscopic analysis method. Results and discussion. It is established that the diphenylamine solution in furfural, provided that it is solidified by sulfuric acid, benzolsulfoacid or mixture of these acids, is a polymer binder capable to form a high-strength material under normal hardening conditions by acid-resistant aggregates. It is also determined that to prepare resin, the ratio of furfural and diphenylamine should be within 1:0.5-0.3 by weight. The resin containing 1 weight part (w.p.) of furfural and 0.5 weight part of diphenylamine is conventionally named FD-1; containing 1 weight part of furfural and 0.4 weight part of diphenylamine -FD-2 and resin with 0.3 weight part of diphenylamine -FD-3. Conclusion. The introduction of nanostructured microfiller into the polymer concrete composition could save expensive resin. Comparison of the technologies for producing FD resin and polymer concrete, as well as preliminary test data of the studied materials, can determine the possible technical and economic advantages of polymer concrete based on FD resin over the polymer concrete based on FA (furfurolacetone) monomer which is currently used in construction of hydro-engineering structures. Polymer concrete based on FD resin has high strength and exceeds the strength of polymer concrete based on FA monomer by 20-25%.

“…The hydraulic structures constructed under the flowing water are subjected to abrasion after a certain period (Creegan et al, 1987), (Liu, Yen, & Hsu, 2006), (Kryžanowski, Mikoš, Šušteršic, & Planinc, 2009). The solids present in the water collide with the surface of the concrete, subsequently weakening and destroying the concrete structure.…”

Abrasion is a major problem in hydraulic structures as they are continuously exposed to various types of water. Henceforth, these structures are susceptible to damage and require heavy maintenance. There is a significant demand in finding new techniques for improving the resistance towards the erosion of the concrete used in the construction of hydraulic structures. This work put forth a comparative analysis of the performance of two different types of concretes towards resistance namely, high-performance fiber reinforced concrete (HPFRC) [steel fibers (30 mm and 50 mm) and polypropylene fibers (19 mm)] and high-performance concrete (HPC). A comparative study was carried out based on their resistance towards wearing and hydro-abrasion erosion. The analyses were conducted using the WMP ECLIPSE method and ASTM C 1138 method. The results indicated that the rate of abrasion could be diminished by 18% based on the types of cement, fibers, concrete and modifications like the addition of silica fume.
