Tarmac (CRH group) has expanded the availability of its Portland limestone cement (PLC) across England and Wales, after recent changes to national concrete standards enabled wider use of the lower-carbon material.
The move follows an update to the BS 8500 standard, which now allows for broader application of PLC in construction. “The changes to BS 8500 are an important milestone in unlocking PLC’s wider use,” said Kevan Greenhalgh, national business manager for bulk cement at Tarmac, said the company was supporting customers with specification-led solutions that meet growing demand for sustainable materials.
Tarmac's CEM II/A-L and CEM II/A-LL 52.5N cement is being produced at the company's Tunstead plant in Derbyshire and its Aberthaw facility in south Wales, and will be delivered via its UK depot network.
PLC includes up to 10 per cent ground limestone, reducing embodied carbon by between seven and nine per cent compared with traditional Portland cement, Tarmac said in a statement.
