EcoSmart concrete was used for the piles pile caps and precast panels of the new light station at Sandheads. High volume fly ash -HVFA- concrete provides greater strength and less permeability which will result in a higher durability in the harsh marine environment. In the case of this project the slower setting time of HVFA concrete was beneficial as the concrete trucks had to be brought to the site by tug boat and barge increasing the time that the concrete was in the trucks before pumping and placing. The manufacturing of the concrete for the Sandheads Light Structure avoided approximately 44% of the C02 emissions that manufacturing of conventional all-cement concrete would have created.
