Allied Concrete is supplying concrete that includes fly ash (as a partial cement substitute) to reduce the heat generated during a large mass concrete pour. The added benefit from using fly ash as a partial cement replacement is the resulting lower embodied carbon of the concrete produced.
The carbon reduction achieved by using 30% fly ash in the concrete mix, is partly negated by other admixtures used in the concrete. As a result, the overall carbon reduction is lowered to 6%.
The project is due for commission in late 2022.
