Abstract

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.
