v.Corn cob ash

Demanding for corn cob ash as cement replacing alternative materials is increased due to less amount of organic content, which proved the binding properties of cement. When we use it as alternative cement replacing materials, it will serve up to 20% by mass, and having advantages increasing the water amount which help as to obtain the desired plasticity as well as the initial and final setting time. Probably it is due to the reduced cement surface area and hence the delayed hydration process. Corn cob ash may therefore be most applicable when a low rate of heat development is necessary.
