Turning Concrete Into an Eco-Friendly Material

Corn Cob Ashes. Corn cobs can be turned into an eco-friendly pozzolan by transforming the material into ash. The cobs are ground into a coarse powder, then slowly incinerated at high temperatures (680°F) for eight hours. The resulting ashes' chemical composition consists mainly of Silicone monoxide (SiO, 66.38%) and aluminum oxide (Al2O3 7.48%).
