The ducts are then filled with grout. Bridges created in this manner have expert significant corrosion in the tendons, so exterior article-tensioning may well now be utilised through which the tendons run alongside the outer floor on the concrete.
Recycled mixture concretes are conventional concrete mixes Along with the addition or substitution of natural aggregates with recycled aggregates sourced from construction and demolition wastes, disused pre-Forged concretes or masonry.
