Effect of calcination temperature on Portland cement clinker partially replaced with calcined limestone overburden clay

Abstract Calcined limestone overburden clay was investigated as a supplementary cementitious material (SCM) for partial clinker replacement. Cement blends containing 30%, 50%, and 70% calcined clay, produced at 500–800°C, were cured for 1–90 days and evaluated for mechanical, dur...
