Early strength concrete at rail ballast yard
The client wanted to replace their badly worn ballast transfer facility at Ruislip, North East London. The slab area to be replaced was 4200m2 at 300mm depth and the yard was to be reconstructed in two phases with 50% of the yard to remain available to Metronet for ballast transfer activities at all times. The new slab was also to be trafficked at an early age to minimise disruption to the client and to minimise program time.
Why Toproc ES?
Toproc ES microsilica concrete was specified by White Young Green to achieve a high abrasion slab to comply with Class AR0.5 (Special) BS8204-2: 2003.
Toproc ES was utilized to achieve an abrasion resistant cast insitu concrete. Toproc ES is one of a range of 14 end use specific formulations. Its typical 24-hour strength is in the range of 30 to 40N/mm2 and its typical 28-day strength is 70 to 90N/mm2.
It is the high compressive strength of Toproc ES that gives excellent abrasion resistance to resist damage. The long-term wear resistance of our Toproc ES has been well proven in many high abrasion applications.
