Geopolymer concrete is a material that is thought to be an alternative to normal concrete, produced to reduce
CO2 emission sand high energy consumption from cement production and to evaluate waste materials. In this
study, samples of geopolymer paste produced with pumice powder and NaOH solution were produced by
replacing 20, 30 and 50 % waste colemanite with pumice powder, and the compressive strength values were
determined by curing at 60oC for 7 and 14 days determined according to the preliminary tests. According to the
results of the study, it was determined that colemanite waste decreased the compressive strength values in
geopolymer concretes produced with pumice at certain rates and suggestions were presented for further studies.
