Biomass ashes to produce an alternative alkaline activator for alkali-activated cements
(2022-02-01)
In the last decade, herbaceous and agricultural biomass have been used as an alternative energy source. As consequence, large amounts of residual ashes containing potassium (potassium-rich ashes) have been generated. Olive ...
Comparative Study of the Use of Different Biomass Bottom Ash in the Manufacture of Ceramic Bricks
The present study evaluates the suitability of several types of biomass bottom ashes [wood bottom ash (WBA), pine-olive pruning bottom ash (POPBA), olive stone bottom ash (OSBA), and olive pomace bottom ash (OPBA)] as an ...
New inorganic binders containing ashes from agricultural wastes
(2017-01-01)
The using of wastes in the design of new binders for construction is the key for the success of new developments regarding environmental, technical, and economic issues. Biomass ashes usually contain reactive compounds for ...
One-part blast furnace slag mortars activated with almond-shell biomass ash: A new 100% waste-based material
(2020-08-01)
The use of almond-shell biomass ash (ABA) as an alkali source in one-part blast furnace slag (BFS) mortars activation was investigated for the first time. The chemical composition of ABA revealed high alkalinity ash to be ...
Design and properties of 100% waste-based ternary alkali-activated mortars: Blast furnace slag, olive-stone biomass ash and rice husk ash
(2020-01-10)
Alkali-activated cements (AACs) technology is being widely investigated as a replacement for ordinary Portland cement (OPC) for environmental benefits. Blast furnace slag (BFS) is one of the most well known precursors used ...
Investigation of using bottom or fly pine-olive pruning ash to produce environmental friendly ceramic materials
The present study investigates the feasibility of using fly or bottom biomass ash as a partial replacement in the production of eco-friendly construction materials. The fly and bottom ashes from combustion of biomass (olive ...
Sugarcane bagasse ash: new filler to natural rubber composite
(Assoc Brasil Polimeros, 2014-11-01)
Waste recycling has been the subject of numerous scientific researches regarding the environmental care. This paper reports the redirecting of sugarcane bagasse ash (SBA) as new filler to natural rubber (NR/SBA). The NR/SBA ...
Olive-stone biomass ash (OBA): An alternative alkaline source for the blast furnace slag activation
(2018-07-30)
Alkali activated materials (AAM) are being investigated as an alternative binder that could be more eco-efficient than Portland cement. The effect of olive-stone biomass ash (OBA) on the activation of blast furnace slag ...
Characterization and evaluation of rice husk ash and wood ash in sustainable clay matrix bricks
This study analyzes the feasibility of using biomass combustion ash waste (rice husk or wood ash from boards) as secondary raw materials in the manufacture of clay bricks.
The ash was characterized using particle size ...
