FOAM CONCRETE

This paper reviews the Dutch approach to the use of foam concrete in The Netherlands and at Canary Wharf in the London Docklands. Its first part gives some general information about foam concrete and some information about its specific applications in The Netherlands, where it is now an accepted building material. The Dutch concrete research association (CUR) has issued two foam concrete recommendations, and in 1990 initiated a large test programme for obtaining a database of foam concrete properties as a function of its density. Foam concrete consists of cement, water and foam, to which several fillers, aggregates and admixtures can be added. Its material properties are strongly affected by its mortar/foam ratio, cement/water/aggregate ratio, foaming agent, hydration speed and workability. Examples are provided. It can be produced by the wet mortar method or dry mortar method. Its possible applications are enormous and include: replacement of existing soil, lateral load reduction, soil stabilisation, bearing capacity enlargement, raft foundation, blindings, roofslopes, precast sandwich elements, sports fields, athletics tracks, filling of pipes and support of tank bottoms. Its most important properties for these applications are its: (1) light weight; (2) thermal insulating capacity; (3) pumpability and high workability; (4) low costs per unit volume; (5) rigidity and high bonding. The second part of the paper describes the use of foam concrete in the Canary Wharf Project.
