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”

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”
