چکیده
Abstract This study aimed to determine the abrasion resistance of ultra-high-performance concretes (UHPCs) for railway sleepers. Test samples were made with different cementitious material combinations and varying steel fiber contents shapes, using conventional fine aggregate. A total 25 UHPCs two high-strength (HSCs) selected evaluate their depth wear bulk properties. The results coefficient variation (CV), relative gain in abrasion, index studied also obtained discussed. Furthermore, a comparison was on those HSCs typically used prestressed concrete outcomes this revealed that displayed excellent against well above HSCs. Amongst utilized combinations, silica fume as partial replacement cement performed best whereas mixtures containing fly ash showed highest wear. addition fibers had more positive influence than it did compressive strength UHPCs.

Ultra High Performance Self Compacting Concrete
Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...
