Abstract :
Our social Duty in the construction management leads us to the assurance achievement of sustainable development for usage materials and procedures employed during the design and construction. Controlled low strength materials, provided specific functional properties, especially as a reliable filler and alternative to conventional backfill and compaction method during construction of industrial projects. In the last decade, CLSM showed that can provide the capability of buried waste excavated and also hazardous by product materials. In addition it is obvious that can reduce the environmental pollution and degradation caused by usage waste material instead of nonrenewable resources. According to these properties CLSM has an effective role to improve the sustainability. In this research, the controlled low strength material applications, capabilities and its sustainability key factors studied in construction industries. Laboratory research surveyed the possibility of utilize the excavated soil as waste materials (Marl) in CLSM mix design. The procedure for utilize the waste material achieved and showed the best option mix design for producing of controlled low strength materials in Hormozgan region of Iran. Also the results of AHP analysis indicated that proposed CLSM procedure is sustainable as compared to the conventional approaches of embankment and soil compaction.
