In this study, the effects of pozzolanic ingredients such as ground granulated blast furnace slag (GGBS), nano-clay (NC), metakaolin (MK) are investigated in basalt fibre cementitious composites (BRC). Basalt fibers (BF) were used in high volumetric ratio (2%). The variation of flexural characteristics are addressed from early days (3 days) to long term (120 days) curing periods. Durability aspect of BRC in harsh conditions is another issue regarding heat-rain aging tests. The initial experiments on control samples (100% cement) indicated that the hydration deposits accumulated on basalt fibers and made the pull-out mechanism difficult. The main target is to save the flexural characteristics even in harsh environmental conditions. After the detailed experimental studies, it is revealed that especially MK usage promises to enhance the durability performance of BRC. It is evident that the implications from these experiments are valid for basalt fibre reinforced concrete (BFRC) as well.
