The Design and Application of Ballastless Track Enhanced Concrete Mineral Admixture

Abstract:

Calcium formate and superfine powders comprised of fly ash, slag and silica fume have been used as raw marerials in this research. The results showed that when superfines powders were mixed with 1.5% calcium formate in a fixed porpotion, the 1 day and 28 day compressive strength of concrete can increase 133.7% and 115.9%, respectively.
