External Concrete Hardstandings

Project: 8,000m2
Work carried out: External Concrete Hardstandings
Specification: Durus @ 4kg /m3 & 0.91kg/m3 of Fibrin XT fibres
Concrete: C32/40

In this particular project the original design was for a 200mm thick slab with C40 air entrained concrete reinforced with one layer of C283 mesh. After reviewing the loading, ground conditions and design criteria an alternative design was suggested.

This included the possibility to reduce the slab thickness to 180mm with the addition of 4Kg / m3 of Durus fibres. Fibrin XT fibres were also used in lieu of the air entraining agent (AEA), and to increase the hardened state properties of the concrete.
