| More Details: | In this study, first, synthetic wollastonite microfiber (SWM) with a high aspect ratio (44:1) was produced with a special three-stage production method. Then, fly ash and ground granulated blast furnace slag-based engineered geopolymer composites (FA+GGBFS-based EGCs) were developed. SWM was used in different proportions instead of FA. The compressive strength of EGCs, changed in the range of 88.1-111.1 and 95.1-122.6 MPa at 7 and 28 days, respectively. Additionally, EGCs containing 6% SWM performed the best, considering both ‘‘increasing deformation capacity’’ and ‘‘maintaining the bearing strength by fiber bridging after crack’’, since they acted like a fiber owing to the acicular particle structure of SWM. Moreover, it can be said that the presence of the SWM mineral in the pore system, ensured pore discontinuities in the matrix because of its acicular particle structure. Consequently, the mechanical, durability and dimensional stability properties of EGCs improved with SWM. |
