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

چکیده مقاله

Excavation and backfill operation usually have a significant contribution in industrial construction activities. Excavated material is not always suitable for backfilling. One of unusable material as an engineering fillers is Marl. Removal of this waste material from the operation place import the large amount of wastes in to the environment and cause the high cost of transportation to projects. On the other hand, enormous mining operations and transportation is necessary for preparation the large amount of suitable soil from borrow materials for embankment that cause destruction and irreversible changes in natural resources and charge budget to project. This article focuses on the use of the excavated soil as waste materials (Marl) in the industrial area of Bandar Abbass in Hormozg region of Iran for engineering fillings. A part of the studies conducted in other countries were introduced. Field investigation and laboratory research surveyed the possibility of utilize the excavated soil as waste materials (Marl) in CLSM mix design. Physical, mechanical and chemical research out comes and durability test on 34 various mix design shows that the optimized procedure is 40% Marl as waste material, 60% Red Soil of Gachin mine as borrow material, 90 kg cement and 542 liter water per cubic meter mix design. The results of research indicated that proposed CLSM procedure is a reliable filler and alternative to conventional backfill and compaction method during construction of industrial projects as reduce the waste material in Hormozgan region of Iran.
