Experimental study on the application of red mud to controlled low strength material made of excavated soil

Abstract To improve the resource utilization of solid waste, excavation abandoned soil and red mud, a by-product alumina industry, were introduced into preparation controlled low strength material (CLSM). By carrying out flowability test, bleeding test compressive relationship between properties CLSM mixture amount mud was analysed. The experiment results indicate that rate decrease with increase content. When content is less than 20%, shows good flowability. addition can accelerate completion time play positive role in stability mixture. 10%, reaches maximum, while other contents decreases For made excavated soil, has application prospect terms strength.
