A RESEARCH ON THE PHYSICAL FEATURES OF CONCRETES WITH FERRO-CHROMIUM SLAG

Abstract

In this study, waste ferrochromium slag is used instead of using natural aggregate, and low density concrete is produced. For this purpose, slag aggregate is mixed with 10%, 30%, 50% and 70% cement to produce samples. The tests applied to the samples show that an increase in slag in the mix decreases thermal conductivity, specific heat capacity and comprehensive and tensile strength while porosity and water absorption capacity increases. If slag aggregated concrete is used for the structural member of a building, i) factory waste ferro chromium slag will be utilized and contributed to economy. ii) The use of slag in building concrete, bricks, briquettes and panel walls will lower the heating expenses and facilitate energy saving.
