Route map for low carbon concrete
Approximately 5% of the global carbon dioxide (CO2) emissions caused by humans currently arise from cement production. As a consequence, there is commercial interest in developing low-carbon cements and related binders suitable for use ‘at scale’ in concrete production. One variety of these is known as ‘alkali-activated binders’ or ‘AA binders’. Alkali-activated binders and concretes … Continue reading “Route map for low carbon concrete”

Research on novel cements to reduce CO2 emissions
‘Concrete is likely to continue to be the primary volume construction material for most structural applications and its use is likely to grow in future. Portland cement (PC) and blended PCs are currently the only economic binders for concrete that can match the performance and durability requirements under the wide range of conditions to which … Continue reading “Research on novel cements to reduce CO2 emissions”

BRE introduces new test programme and guidance for low carbon cements
BRE is now offering testing services related to new performance standard PAS 8820, which has been developed for manufacturers, specifiers and designers of concrete containing alkali-activated cementitious material (ACCM*). Designed to encourage the use of AACMs in the construction industry because of their low carbon and improved fire resistance properties and resistance to chemicals and … Continue reading “BRE introduces new test programme and guidance for low carbon cements”

Alkali-activated binders for precast and ready-mixed concrete products
Alkali-activated (AA) binder technologies can utilise locally available clays, waste materials and industrial by-products in combination with a manufactured chemical activator. The production of AA binder technologies uses less energy and produces less carbon dioxide than conventional Portland cement (PC). Although low-carbon concretes made from AA binders share some materials in common with conventional PC-based … Continue reading “Alkali-activated binders for precast and ready-mixed concrete products”
