This paper presented metakaolin based geopolymer which was </div> <div>manufactured by partially replacing metakaolin with colemanite with different percentages (10%, 20%, and 30%), to investigate </div> <div>the effect of colemanite on the mechanical properties of geopolymer. Then a comparison was carried out between non-fibrous </div> <div>specimens and basalt fiber reinforced ones to evaluate the improvement in terms of flexural and compressive strength of </div> <div>metakaolin-based geopolymer. The results showed that replacing metakaolin with 10% colemanite and adding 1% basalt fiber </div> <div>achieved 28.17% improvement in flexural strength at age 7 days compared to the reference sample. </div>}, number={2}, publisher={Yildiz Technical University}
