Alternative cementitious binders using high volume of biomass ash
Principal Investigator
Prof. Piyush Chaunsali
Objective
- To generate alternative cementitious binders using high volume of biomass ash.
Description
- India is the 3rd largest energy consuming country in the world. Principal source for energy production is fossil fuels i.e., 60-70% of the energy. The total estimated availability of biomass is ~ 750 MT per year, The total land area in India is ~ 329 million hectares. Net covered area by agricultural land is ~ 197 million hectares, Biomass ash derived from agricultural wastes has potential to be used in alternative binders, Chemical activation of biomass ash enabled its use as a binder for making bricks, 50-70% (by wt.) utilization of biomass ash could be achieved for desired properties (strength and water absorption).
Impact
- Establishing composition-reactivity relationship for Indian biomass ashes, Developing a framework for high volume utilization of biomass ash in alternative cementitious binders, Exploring potential of biomass as an alternative fuel in cement manufacturing/ clay calcination.
