12%Furthermore, ball milling technique coupled with chemical and physicochemical pretreatments has been shown to facilitate lignin removal, reduce cellulose crystallinity, and increase the specific surface area which ultimately improves the digestibility of lignocellulosic biomass.
Ball milling was used to improve the dispersion of GO in a cement matrix in a planetary ball mill. Results indicated that the process had a negligible effect on the morphology of the GO but led to a 6.8% increase of the number of defects it contained. By adding 0.03 wt.% GO to the cement paste, its compressive strength increased by 9%, and the ...
