Paper Title:
Preparation of Railway Concrete Sleeper Blended with Perlite Admixture
  Abstract

The experimental data about concrete incorporating perlite admixture revealed that perlite admixture in content of 10%-20% replacing cement in equal mass enhanced effectively the workability, late-age mechanical strength and durability for concrete. The railway sleepers made of concrete with perlite admixture substituting for 20% cement were probingly produced in production line of manufactory without any modification to the conventional equipment or procedures. The summary was concluded that the concrete sleepers with 20% perlite admixture not only have met requirement of product quality, but also far better than demand of product quality on fatigue resistance, meanwhile prior to reference concrete sleepers without mineral admixture on major properties, such as fracture resistance. Consequently, the concrete sleeper considerably requires less maintenance and offers a longer service and reduced life-cycle costs.
