APTIDCO

Flowcrete India has worked with the Andhra Pradesh Township and Infrastructure Development Corporation Limited (APTIDCO) to provide advanced admixtures that would strengthen and improve the concrete used for a brand new, large-scale residential complex.

APTIDCO was tasked with creating affordable housing in Andhra Pradesh. In the state’s Godavari District a large number of four-storey buildings were created to provide the region with a lot of new, high-quality residences.

To ensure that the concrete used in these developments would be up to the task at hand, Flowcrete India provided a number of its specialist concrete additives. This included 100,000 m³ 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.
