A concrete mix developed specifically for rail projects has been used for the first time in the UK, on the mainline link between Glasgow and Edinburgh.
Hope Construction Materials developed the bespoke product to use with the Slab Track Austria system along the 330m long Winchburgh Tunnel section of the track.
Work to electrify the line means the floor of the tunnel must be lowered.
The company’s technical team developed the concrete to produce a product that had extended workability and high early strength. They used a blend of selected aggregates, cement and specialist admixtures.
Hope Scotland business manager David Morrow said: “We took into consideration all of the attributes needed for the concrete, ensuring it was strong, free-flowing and had a sufficient working time.”
