Study of the possibilities of using Red Mud as an additive in concrete and grout mortar

Start date 01/04/2013
End date The project is closed: 31/03/2014

​Red mud is an industrial waste from aluminium production. This is a kind of solid waste with the lowest rate of reuse in the world. Red mud contains high alkali and has high specific surface area which may be utilized as adsorption agent for fixation of radioactive ions from nuclear waste.

This project intends to investigate the possibilities of using red mud as an additive in concrete and grout mortar for better fixation of radioactive ions from low radioactive nuclear waste. The project is in a cooperation with two Chinese universities where different amounts of local red muds will be added to concrete and grout mortar for evaluation of the effects on workability, mechanical strength, water permeability and adsorption capacity of Ce-ions.


The project is carried out at the Division of Building Technology in the research group Building Materials.

Keywords: Red mud, cement, concrete, grout mortar, adsorption, radioactive ions
