Properties of the Concrete for the Slab Ballastless Track of CRTS III

Abstract:

Experimental research was conducted using concrete produced by adding the polycarboxylic-type water-reducing agent. The cement, sand, aggregates, fillers and water-reducing agent were used as the important raw materials for the concrete. Then the following properties of the concrete were analyzed: compressive strength, elastic modulus and frost resistance. The compressive strength was 84 MPa at 56 days and the modulus of elasticity was 45.3 GPa at 28 days. Therefore, the water-reducing agent played an important role for the concrete. All the properties met the technical requirements of the CRTS III track plate.
