70+ Uses for Wood Ash
Study on Bagasse Ash As Partial Replacement of Cement in Concrete
Researchers in Canada are developing guidelines to use waste materials from the pulp and paper industry as a sustainable alternative for road construction. The construction industry has long sought to use waste materials from the pulp and paper industry as possible fillers for building products such as cement, but for years these materials have ended up in landfills. Now, researchers at The University of British Columbia UBC Okanagan are developing guidelines to use this waste for road construction in an environmentally friendly manner. To help create such guidelines, the researchers turned their attention to wood-based pulp mill fly ash PFA , which is a non-hazardous commercial waste product, to investigate the potential of using a waste material from this industry in constructing roads. The North American pulp and paper industry generates over one million tons of ash annually by burning wood in power boiler units for energy production. The new research, co-published with postdoctoral research fellow Dr Chinchu Cherian, investigated using untreated PFA as an economically sustainable low-carbon binder for road construction.
Tobacco waste ash: a promising supplementary cementitious material
This paper for the first time investigates the workability, compressive and tensile strength of concrete containing Fly Ash, Rice Husk Ash and Waste Glass Powder. The cubes were tested for axial compression and tensile tests. The research also investigated the effect of curing regime on the compressive and tensile strength of concrete cube specimen.
