Feasibility study of red mud for geopolymer preparation effect of

The original red mud produced by aluminium enterprises has a very fine particle size but it will agglomerate during storage as shown in Fig 1 [ 24 25 ] so it needs grinding before preparing geopolymer The particle size has a great influence on the properties of geopolymer such as setting time fluidity and mechanical strength [ 26 27 ]

Effect of polyDADMAC on aggregation of clay size particles in red mud
