Study unveils fly ash geopolymer concrete as potential SCM
A new study from Zhejiang University of Technology, China, sheds light on the potential of fly ash geopolymer concrete (FAGC) as a sustainable alternative to Portland cement concrete (PCC), which is a significant contributor to CO 2 emissions. The research, published in *PLOS ONE*, outlines a robust method for predicting the compressive strength of FAGC while optimising its mixture design to ...
BSI publishes guidance on alternative binders
The British Standards Institution (BSI) has published its latest code of practice, “Lower Carbon Concrete – Alternative Binder Systems (ABS) – BSI Flex 350 Version 2”, aimed at reducing embedded carbon in concrete by promoting cement substitutes. This new guidance provides a framework for assessing alternative binder systems (ABS) as viable low-carbon alternatives to traditional Portland c...

National Renewable Energy Laboratory welcomes industry and government leaders
The National Renewable Energy Laboratory (NREL) hosted its second annual Cement and Concrete Decarbonisation Meeting on 30-31 July 2024 at its South Table Mountain Campus, focussing on one of the cement industry's biggest challenges: reducing carbon emissions. Cement production, a critical component in concrete, is responsible for approximately eight per cent of global CO 2 emissions, making ...
COP28 initiative says low demand for green products is deterring investment
Low demand for green products is deterring the necessary investment of up to US$700bn in low-carbon projects within carbon-intensive industries such as steel, aluminium and cement, according to an initiative from the UN Climate Summit. More than 450 major industrial projects worldwide are seeking hundreds of billions of dollars in investment to reduce carbon emissions, according to a state...
Green Island Cement oyster shell cement cuts landfill waste
Green Island Cement is taking the natural resource of oyster shells, which are 91 per cent limestone, to use them as the main ingredient in cement production. By upcycling oyster shells, Green Island Cement is diverting the shells from landfill. In 2023 a total of 3300t of oysters were imported into Hong Kong. Approximately, seven per cent of the island’s greenhouse gases are from food waste....
