Resistance of Building Materials from Recycled Rubble using Lime

Objectives: Recycling the waste materials and debris especially rubbles from demolished buildings. Methods: Environmental problems that have emerged by the non-normative and non-technical disposal of materials, has attracted researchers attention to the recycling of these materials. Available statistics on the composition of the rubbles from buildings in large cities show that bricks and mortar sand, cement, concrete, tile and soil are five main materials of construction rubbles. In this research the possibility of recycling these materials and using them after consolidation and improvement in the litter layer were examined, and to enhance the quality of the materials lime was used for stabilization. Results: Addition of lime increases CBR as well as the resistance of uniaxial compressive of these materials.
