Geopolymer combines the merits of cement and ceramics, we can make materials with the properties of ceramics by a process like cement. Water reducing agents are popular in cement industry.
The question is what will happen in geopolymer?
Experiences carried out with geopolymer cements show good results with regular water reducing agents used for Portland Cement. The optimal content should not be greater than 1 per cent by weight of the cement. Higher content induces lower mechanical properties.
