Recirculation of wood ash from energy production to forest soil improves the sustainability of this energy production form as recycled wood ash contains nutrients that otherwise would be lost at harvest. In addition, wood-ash is beneficial to many soils due to its inherent acid-neutralizing capabilities. However, wood ash has several ecosystem-perturbing effects like increased soil pH and pore ...

This paper summarizes some of the information contained in a comprehensive document about the beneficial use of municipal waste combustion (MWC) residues. The document entitled "Beneficial Use and Recycling of Municipal Waste Combustion Residues A Comprehensive Resource Document", presents information from world-wide sources and contains numerous references. Information is presented on ash char...

Ash content of paper sheet is an important performance index in paper-making process. X-ray ash sensor based on the Fe-55 radiation principle can detect paper sheet ash content accurately. Here considering the influence of paper absolute dry fiber weight and moisture content, real online ash signal can be achieved by algorithm developing, data processing and signal compensation, and this signal...

Many research studies were carried out for effective utilization of fly ash and pond ash in building industry as it possess suitable pozzolanic properties .They are produced in large quantities during the combustion of coal for energy production and recognized as an environmental pollution. Fly ash and Pond ash utilization in building materials have many advantages like cost effectiveness, envi...

Application of bio-fuel by-product sugarcane bagasse ash SBA as. Including sugarcane bagasse ash SBA13, recycled paper mill waste4.as bagassios. In this paper, Bagasse ash can be utilized by replacing it with fly ash and lime in fly ash bricks. Trial bricks of size 230x100x75 mm were tested.bagasse ash SCBA, several trials were conducted to define optimum burning time and temperatures. SCBA use...

Recycled materials like Bauxite Residue (Red Mud) and Fly Ash are prevalent in recent feasibility studies on reused geotechnical engineering applications. Red Mud is a mining waste from aluminum manufacturing, by-product of coal combustion power plants. Nevertheless, to fully reveal the using those for constructing above-ground earth structures, better understanding their unsaturated performanc...

Natural fiber reinforced composites are becoming popular in various industrial and commercial applications as structural components. Unlike conventional materials, machining of is critical due to its heterogeneous structure. Hence, it necessary understand the behaviour composites. Hybrid with banana fly ash filler polyester matrix were fabricated then evaluated for drilling performance. Drillin...

Surface transportation networks are critical infrastructure that are frequently affected by volcanic ash fall. Disruption to surface transportation from volcanic ash is often complex with the severity of impacts influenced by a vast array of parameters including, among others, ash properties such as particle size and deposit thickness, meteorological conditions, pavement characteristics, and mi...

Previous laboratory studies indicate that coal combustion wastes (a mixture composed of fly ash and other lower volume wastes such as bottom ash; hereafter collectively referred to as ash) adversely affect the health of benthic fish (Erimyzon sucetta; lake chubsucker), but fish in these studies were provided with ample uncontaminated food resources. Because aquatic disposal of ash can also adve...

The study presents the behaviour of wood ash / OPC concrete. Chemical analysis of wood ash, bulk density, sieve analysis and specific gravity of wood ash and aggregates, consistency, setting time and slump test of the fresh paste were conducted to determine the suitability of the materials for concrete making. Mix ratio of 1:2:4 and percentage replacement level of 0, 10, 20, 30 and 40 percents ...
