For generations, OPC has been the only form of
cement available. Considering high amount of cement
annual consumption, more sustainable practices in
cement production and application could lead to
significant CO2 emission. CCA blended cements provide
a unique and valuable alternative to conventional
methods. Replacing a portion of OPC with up to 10%
CCA found to increase the compressive strength of OPC,
enhance insulation performance, as well as increase
workability time. Apart from the observed structural
advantages of CCA blended cements, it is vital to the
environmental sustainability to reduce cement
production emission. Recycling materials that otherwise
would be treated as waste can create endless sustainable
construction opportunities.
