Behaviour of geopolymer concrete circular column using ...

Totally four geopolymer concrete circular columns and two reinforced concrete columns were casted. Two geopolymer concrete columns were wrapped using GFRP sheets by two layers. One reinforced concrete column was casted for wrapping. Short columns were tested in a compression testing machine of capacity 2000 kN.

Novel geopolymer based composites with enhanced ductility ...

24-03-2007  Geopolymer materials have been proposed for various applications due to their excellent fire resistance and low processing cost. One requirement that geopolymer composites need to meet for structural applications is graceful failure, as catastrophic failure during service can result in significant loss of life. In this paper, the properties of novel low cost composites made by infiltrating ...
