Non-Propriety Ultra High-Performance Concrete for Ballast-Track High Speed Railroad Sleepers

This study aims to develop optimized non-propriety Ultra High-Performance Concretes (UHPCs) capable of supporting strength, ductility, and durability required for long-lasting high speed railroad sleepers. Furthermore, this study will use Portland cement, supplementary cementitious materials, regular sand, various combinations of silica to conventional natural sand, different fiber contents and types, and larger aggregate size to produce non-propriety UHPCs with production costs comparable to those of currently manufactured prestressed concrete sleepers.
