Calcined Clays – Performance as Composite Material
Abstract Cements with calcined clays were tested for their performance in mortar, and compressive strength data was collected to quantify the reaction. References were run in all experiments to quantify relative performance differences. Calcined fineness becomes relevant for strength development at high Blaine values of calcined clay. 20% calcined clay substitution shows the best results High substitution rates (35%) make the early strengths worse – compared to OPC Due to an increase of the clinker fineness the performance can be improved Water demand of the blends is not critical for the strength development BM and VRM both show good results – considered in absolute terms, the VRM shows the highest strengths
