Recycling red mud from the production of aluminium as a red cement-based mortar.

摘要: Current management for red mud is insufficient and a new method needed. A series of experiments have been carried out to develop approach effective mud. Mortars without or with 3%, 6% 9% were prepared their fresh hardened properties measured access the possibility recycling in production cement-based mortar. The mechanisms corresponding mechanical performance variations explored by X-ray powder diffraction scanning electron microscopy. results show that mortars present an increase viscosity as compared control. However, little difference found when content altered. It also can be seen increases flow time reduces slump Meanwhile, it mortar provided higher air content. Red eligible adjust decorative colour. Compressive strength improved wh...
