Abstract:
This study presents mechanical and durability aspects of using different waste fillers including Iron powder, Iron concentrate, Coal Powder and Coke, which cannot be reused at industry process (samples from different parts of the Jalalabad Iron Ore Concentrate Plant and Zarand Coking Plant, Kerman, Iran) as well as mineral powder filler as a control sample to replace 3% and 6% of coarse and fine natural aggregate content in RCC. The concretes were investigated for absorption, compressive strength, workability and non-segregation of grains. The experimental results showed that RCCs of iron ore powder filler contents with 6% of the weight of coarse and fine natural aggregates had higher values of 28 days compressive strength and minimum 24-hour water absorption about 2.22%. In addition to that, using this type of waste in concrete may be more environmentally efficient, because this helps to remove some parts of wastes and protects the environment.
