Surveying of Marl Usage as Waste Material in CLSM Utilization for Industrial Project

Excavation and backfill operation usually have a significant contributionin industrial construction activities. Excavated material is not alwayssuitable for backfilling. One of unusable material as an engineering fillersis Marl. Removal of this waste material from the operation place importthe large amount of wastes in to the environment and cause the high costof transportation to projects. On the other hand, enormous miningoperations and transportation is necessary for preparation the largeamount of suitable soil from borrow materials for embankment that causedestruction and irreversible changes in natural resources and chargebudget to project. This article focuses on the use of the excavated soil aswaste materials (Marl) in the industrial area of Bandar Abbass inHormozg region of Iran for engineering fillings. A part of the studiesconducted in other countries were introduced. Field investigation andlaboratory research surveyed the possibility of utilize the excavated soil aswaste materials (Marl) in CLSM mix design. Physical, mechanical andchemical research out comes and durability test on 34 various mix designshows that the optimized procedure is 40% Marl as waste material, 60%Red Soil of Gachin mine as borrow material, 90 kg cement and 542 literwater per cubic meter mix design. The results of research indicated thatproposed CLSM procedure is a reliable filler and alternative to conventionalbackfill and compaction method during construction of industrial projectsas reduce the waste material in Hormozgan region of Iran.
