A range of low carbon concretes.
Vertua is our new range of low carbon concretes, with bespoke designs enabling embodied carbon reductions greater than 70% versus standard concretes (CEM I). The range can also provide additional benefits including increased durability and aesthetic finishes.
The use of Vertua concrete reduces the heat of hydration (the hydration of cement is an exothermic reaction). High temperatures in concrete can generate stresses that could result in early-age thermal cracking. The use of Vertua is recognised as an effective solution to this problem.
Vertua benefits from lower heat generation and takes slightly longer to set, which is particularly useful in warm weather conditions. This is influenced by many factors, including temperature and water/cement ratio. However, an extended setting time means that the concrete will remain workable for longer and this needs to be considered when using these products.
