INTRODUCING FLY ASH-BASED GEOPOLYMER CONCRETE:

MANUFACTURE AND ENGINEERING PROPERTIES

ABSTRACT:

This  paper  presents  the  results  of  a  study  on  fly  ash-based  geopolymer  concrete.The  test  parameters  covered  certain  aspects  of  manufacture  of  geopolymer concrete. The  paper  also  reports  the  stress-strain  behavior  of  the  concrete  with compressive  strength  in  the  range  of  40  to  65  MPa.  Tests  were  carried  out  on 100mmx200mm cylindrical geopolymer concrete specimens.Test results show that  a  good  agreement  exists  between  the  measured  stress-strain  relations  of  fly  ash-based geopolymer concrete and those predicted by a model developed originally for Portland cement concrete.
