US: Solidia Technologies has filed a patent for a new hydraulic cement consisting of Ordinary Portland Cement (OPC) and other supplementary cementitious materials (SCM) including lime, alkali hydroxides, clay minerals and over 10% synthetic pozzolan.

Solidia Technologies said, “In order to reduce global CO2 emissions it is necessary to adopt new approaches to create a new generation of hydraulic cements. The most efficient cement kiln can produce OPC clinker with an associated emission of 816 kg of CO2/t. Blending the ground cement clinker with SCM, which have low or zero associated production CO2 emissions, reduces the total embodied CO2 of the final product. Using a cement with the lowest possible clinker factor for a given application is the most common industry approach to reducing the CO2 footprint of concrete.”
