AB A circular economy is a current tenet that must be implemented in the field of construction.That would imply the study of the possibilities of the use of waste generated, for obtaining materialsthe used in construction as replacements for the raw material used. One of these possibilities isthe substitution of the cement by slag, which contributes to the reduction of cement consumption,decreasing CO2 emissions, while solving a waste management problem. In the present paper, di erenttypes of concrete made by cement substitution with di erent type of slags have been studied in orderto evaluate the properties of these materials. Cement is replaced by slag from di erent steel mills,both blast furnace and ladle furnace slag. The percentages of slag substitution by cement are 30%,40% and 50% by weight. Mechanical, physical and environmental properties have been evaluated.Compressive and flexural strength have been analysed as the main mechanical properties. As faras physical properties go, density and porosity tests were be reported and analysed, and from anenvironmental point of view, a leachate study was performed. It has been found that some kindsof slag (blast furnace slag) are very suitable as substitutes for cement, providing properties abovethose of the reference concrete, while other types (ladle furnace slag) could be valid for non-structuralapplications, contributing in both cases to a circular economy
