Abstract

The overarching goal is to investigate the potential of alternative Supplementary Cementitious materials (SCMs) and their use in cement for the reduction of CO2 footprint in concrete. Where this investigation had two aims:<br/><br/>1) To test if a home-build semi-adiabatic calorimeter can reproduce early age relations similar to the heat release from isothermal calorimetry and mechanical tests [1] for cementitious binders containing SCMs. <br/><br/>2) If the performance and resource efficiency of calcined shale can be increased by combination of limestone fillers similarly to calcined clay-limestone binders or fly-ash containing binders [2,3]. <br/><br/>The scale of concrete used globally makes it one of the main contributors of man-made CO2 emissions [3]. Calcined shale has pozzolanic properties, is available in large quantities as by-products of mining operations, and may thus improve the sustainability of cementitious binders.
