Self-Cleaning Performance of Basalt Fiber–Reinforced GGBS-Based Geopolymer Mortar Containing Nano ${TiO}_{2}$

Tanyildizi, Harun / Yilmaz, Atilla / Açik, Volkan / Demirelli, Kadir

This study examined the self-cleaning and mechanical properties of basalt fiber–reinforced ground granulated blast furnace slag (GGBS)-based geopolymer mortar containing nano ${TiO}_{2}$ . The nano ${TiO}_{2}$ and basalt fiber in mixtures were used at 0%, 0.25%, 0.5%, and 1% by weight of GGBS. The cubes ( $50 \times 50 \times 50 mm$ ) and prisms ( $40 \times 40 \times 160 mm$ ) samples containing nano ${TiO}_{2}$ and basalt fiber were produced and cured in the oven for 24 h at 60°C. Then, these samples were kept at room temperature at $23 ° C \pm 2 ° C$ for 28 days. Lastly, the compressive strength, flexural strength, ultrasonic pulse velocity, capillary water absorption, and self-cleaning tests of GGBS-based geopolymer mortars were carried out. In this study, the Rhodamine-B test was used to determine self-cleaning. This study showed that the compressive strength, flexural strength, and ultrasonic pulse velocity values of the GGBS-based geopolymer mortars increased as the nano ${TiO}_{2}$ and basalt fiber ratios increased, but their capillary water absorption coefficient decreased. Also, this study found that the self-cleaning rate of GGBS-based geopolymer mortars containing 1% nano ${TiO}_{2}$ was obtained as 50.62% at 28 days.
