Recycling is a logical option for materials that are not suitable for composting. One of these materials is iron mines waste that, according to their compounds, can be used as a substitute part of cement in concrete. For this aim, rheological and mechanical properties and durability of light weight self-compacting concrete (LWSCC) containing Sirjan iron mine waste (SIMW) as partial substitute of cement is presented in this paper. For this purpose, part of cement was replaced with 5, 10, 15 and 20 wt% SIMW. It’s founded that the addition of SIMW as substitute part of cement decrease flowability, viscosity and filling ability of LWSCCs but all of the mixtures were in the allowable range accordance EFNARC (2005). Replacement of 5 wt% and 10 wt% of cement with SIMW resulted 8.6% and 20% increase in compressive strength with respect to control mixture, respectively. By increasing percent of SIMW compressive strength decreased. This trend was observed for tensile and flexural strength and water penetrability of LWSCCs.
