Keltbray Piling has said it has achieved a landmark for the UK construction industry with construction of the first permanent pile using a zero cement concrete.
Keltbray undertook the work using the Cemfree concrete on a new housing development for Taylor Wimpey at Mount Pleasant where it is installing a secant wall and breaing piles for main contractor Bouygues.
Cemfree is an ultra-low carbon alternative to traditional cement concrete developed for the UK by DB Group. According to Keltbray, Cemfree has all of the structural characteristics of traditional concrete and is more sustainable as it is more resistant to chloride ingress and requires fewer construction joints and less crack-control steel when used within key structural elements.
Keltbray Piling managing director Stuart Norman said: Using Cemfree in the piled foundations over traditional concretes has the potential to save up to 80% in embedded carbon. These works have been a part of a growing collaboration effort with our industry partner, the DB Group, which manufactures the Cemfree binder product. This is Keltbray’s fifth project where we have used Cemfree but only the first time we have used it for permanent works and so far we’re delighted with the results.”
