To ask Her Majesty’s Government whether the HS2 project intends to use secondary aggregates, and if so, in which types of concrete required for Phase 1 of that project.
27 April 2016
As part of our overall sustainability policy for HS2, we plan to use both secondary and re-cycled aggregates in structures which are designed with concrete. Their use, along with the types of concrete to be used, will be dependent on the specific design characteristics of individual HS2 structures and will be subject to the detailed design process in due course. The design process will also take into account other important sustainable factors such as material availability and logistics.
