APTIDCO

To ensure that the concrete used in these developments would be up to the task at hand, we provided a number of its specialist concrete additives. This included 100,000m³ of the modified carboxylate polymer admixture Eucon HC R4 as well as 650,000 m³ of the polycarboxylate plasticising admixture Plastol 3610 V. 

Combined into the concrete, these products deliver a number of crucial construction properties. For example, Eucon HC R4 is ideal for increasing compressive strength, reducing permeability and reducing shrinkage while improving durability and the finished appearance. Plastol 3610 V provides similar advantages and is particularly effective at achieving high strength concrete very quickly and improved finishing characteristics.

During the APTIDCO project, self-compacting concrete (SCC) with 50% of the mixture replaced with GGBS was used. The M-30 grade concrete had a flow rate of 550-650 mm. 750,000 m³ of this concrete was installed in only 20 months and all of it met the requirements of the EFNARC guidelines for SCC
