Geopolymer (GP) mortars are highly acknowledged in the concrete industry as superior cement
alternatives, providing an environmentally benign and sustainable building solution. Micro-fibers and
nanoparticles are crucial for improving the mechanical characteristics of fiber-reinforced (FRF) GP mortars
and expanding their practical application. By adding different amounts of nano-Titania, this work seeks to
enhance the mechanical behaviour of GP mortars based on micro basalt-FRF fly ash. Two weight percent
of micro-basalt fibres (MBF) are added to GP mortars together with four different titanium doses (varying
from 1% to 4%). For comparison, a control model with 2% MBF and no Titania is also created. According
to the findings, micro basalt-FRF-GP mortar's toughness modulus, flexural strength, elastic modulus, and
compressive strength are all increased by 27%, 61%, 8%, and 66%, respectively, when 3% titanium is
added.
