Working with alternative concrete binders: BSI’s new guidance

Traditional Portland cement, a major ingredient in conventional concrete, plays a huge role in global CO2 emissions. This is because its production requires a lot of energy. In the UK alone, according to the European Ready Mixed Concrete Organisation, about 11.7 million tonnes of Portland cement are used annually. This results in millions of tonnes of CO2 emissions, comprising nearly 90% of the greenhouse gases linked to concrete production.
