In this work we studied the effect of pre-treatment of low-grade flax product (flax tows, FTs)
by cleaning it mechanically from shives and weeds, followed by mercerization with a 5%
aqueous NaOH solution and ultrasonic (US) treatment (22 kHz, 500 W) in alkaline medium,
on the mechanical properties and microstructure of fly ash-based geopolymer (GP)
composites. A series of three-point bending flexural tests was conducted on several types of
GP/FTs composites while ATR-FTIR spectroscopy, scanning electron microscopy, and …
