Abstract: As an inorganic–organic composite material, cement and emulsified asphalt (CA) mortar has been used widely in ballastless slab track structures, and its performance is influenced significantly by environmental conditions. ...

Abstract: The filling layer of a China rail track system III (CRTS III) type ballastless track structure of a high-speed railway is a complicated structure typically constructed from self-compacting concrete (SCC). Excellent properties ...

Abstract: Conventional portland cement–based aerated concrete needs autoclaved curing in order to obtain high early-stage strength. Magnesium phosphate cement–based lightweight materials, such as aerated magnesium phosphate cement ...

Abstract: Theoretically, there are two approaches to reducing the vibration induced by railway transit in cities: lowering structural stiffness, often used in subway design to isolate vibration, and absorbing the vibration by improving ...

Abstract: Particle-packing theory has been widely applied in the field of composite particle materials, and packing density (Φ) is an important parameter to evaluate the compactness of particle packing. In this paper, the rheological ...

Abstract: Self-compacting concrete (SCC) is widely used in the China Rail Track System (CRTS) III slab ballastless track filling-layer structure for high-speed railways (HSRs). In cold regions, the thin filling-layer SCC is subjected ...
