Corn stover cellulose and hemicellulose has been utilized as a substrate for ethanol production using Saccharomyces cerevisiae. Lignocellulosic materials through a process of pre-treatment, hydrolysis and fermentation produces ethanol from a corn stover. With the cellulosic ethanol process, left over material which has lignin and some cellulose in it can be burn out to get the ash. Adding this high lignin ash to the cement, makes concrete strong and durable. Corn stover has the potential for use as a supplementary cementitious material (SCM) for concrete. On the pozzolanic reactivity of corn stover ash (CSA), the effects of distilled water and diluted acid pre- and post-treatments were investigated. The possible application of high lignin residue (HLR), a bioethanol by product, in the synthesis of SCM was also looked at. When utilised as a 20% replacement for cement in the system, pre-treatment CSA and high lignin residue ash (HLRA) improved the early reactivity of cement paste, however unpretreated CSA was discovered to significantly stifle the hydration reaction. From samples containing HLRA, the maximum compressive strength was attained.
