The present research reports on the results of some experiments dealing with the recycling of steel scale waste in the production of mortars. Materials were prepared mixing a commercial CEMII/B-LL cement, a steel scale waste, a commercial natural aggregate, superplasticizer and water. Natural aggregate was replaced with different proportions (5, 10, 20, 30 and 40wt%) of steel scale waste. Water absorption, apparent density, compression strength and thermal conductivity were measured after 28d of curing. After curing, all hydrated materials displayed: good compressive strength and low water absorption; increased apparent density with steel scale addition; improvement of thermal conductivity in materials containing up to 10wt% steel scale addition
