Cement manufacture consists of quarrying, processing, and calcining at 1450°C, thereby high energy input and carbon dioxide emission. To reduce energy consumption, researchers and practitioners have been searching for alternatives to cement. Partial substitution of cement with pozzolanic materials or industrial products is a viable option.
