Lightweight Concrete Lifts London Property
Capital Concrete have supplied Daval Construction with a specialist Lightweight Concrete for the construction of a major project in Handyside Street, King’s Cross.
The project, designed by J Coffey architects, is part of a series of
planned redevelopments in the 67-acre King’s Cross Estate to uplift and
rejuvenate the area.
Working on a property above the underground railway tunnels of King’s
Cross, the weight of the concrete was critical in this high-profile
refurbishment. Concrete Capital Concrete was chosen to supply the
lightweight concrete having had previous experience of delivering
concrete in a variety of projects across the Capital.
To meet the project’s specifications, a lightweight aggregate
concrete (LWAC) with a plastic density no greater than 1800kg/m3 was
required for the slab to prevent excessive weight causing issues with
the London Underground tunnels beneath. In response to this challenge,
Argex Expanded Clay aggregates supplied by Euro-Agg’s was chosen for
this application utilising a blend of Argex coarse and fine aggregate to
achieve a pumpable grade LC35/38 strength low density concrete mix.
Jack Sindhu, Technical Manager for Capital Concrete, said: “This
project demonstrates the importance and relevance of lightweight
concrete in modern construction and the various applications the
concrete can be used for. Its application in King’s Cross, with the
requirement to be pumped over 90 metres, being an excellent test of its
specialist capabilities. The requirement for lightweight concrete by
specifiers is proving to be a valuable asset when working in complex
urban landscapes.”
