In the wake of recent publicity regarding carbon emissions, the construction industry has experienced unprecedented interest in low-carbon alternatives to traditional building materials. Many are not only concerned with meeting potential future legislated targets, they’re also aiming to satisfy internal company goals to meet the challenges of a carbon-neutral future.
One ready-mix concrete supplier, Capital Concrete, has responded by dedicating two 60-tonne silos of a low-carbon alternative to traditional cement, called Cemfree, at their new batching plants in London, ready to service the demand of ready-mix concrete within the M25. They are currently the only RMC supplier in the London area stocking Cemfree in this way.
Luke Smith, Managing Director of Capital Concrete, says “We’ve seen customer interest pick up recently, interest which is clearly linked to the growing 
importance of environmental considerations in construction build designs. Capital Concrete is now a leading supplier of Cemfree in the London area and we’re able to supply high volumes of this product anywhere in the London market. We have a strong reputation for developing cutting-edge solutions and niche products and Cemfree represented an opportunity to do both simultaneously. Supplying this product to the highest level of quality control is easy at our new state-of-the-art, high output, wet-batch concrete plants at Silvertown and at Wembley, where we have dedicated a silo at each site exclusively to Cemfree.”
Adam Gittins, Commercial Manager at Cemfree, adds, “Cement alternatives have become the ‘holy grail’ in the quest to reduce 
the carbon expense of producing traditional cement – and while low-carbon technology is already here, the issue could come down to logistics, supply and quality control for contractors. Lately however, we’ve seen an unprecedented number of enquiries from both ready-mix concrete and volumetric suppliers who are keen to get Cemfree ‘on tap’, so there is now no reason not to routinely specify a lower carbon alternative for a build. In fact, Cemfree has already been used in some very prominent build projects.”
“It’s just a matter of making the right moral choice in the context of a larger environmental issue especially since all other features of Cemfree stack up as well as, if not better than, those of traditional cement products for the appropriate application.”
