An Experimental Study on Partial Replacement of Cement by Red Mud for M-30 Concrete
Abstract
Red mud derived from alumina refineries through the Bayer process is a waste material. The particle size distribution of the red mud is similar to cement. The potential use of the red mud to replace cement is assessed by conducting a range of fresh and hardened properties tests (such as slump flow, compressive strength, and flexural strength). Development of concrete is a desirable achievement in the construction industry in order to overcome problems associated with cast-in-place concrete. Various investigations have been carried out and has been used in practical structures, mainly by large construction companies. In this study, the cement content was partially replaced with red mud. Red mud improves the flowing and strengthening characteristics of the concrete.
