China has one of the largest coal mining industries in the world. Electricity in this country is mostly generated by coal-fired electric power plants. These plants produce huge amounts of ash each year. In 1988, Shanghai city alone produced nearly 1.8 million tons of ash. During the last two decades, a substantial amount of research work conducted by the Shanghai Research Institute of Building ...

In thermochemical utilization of biomass, ash produced during the process is a major problem that can result in decreased performance and increased in difficulty during operation. Preliminary assessment of potential ash related troubles prior to the use of a specific biomass is valuable, even if it is only a general guideline. In this work, tendency of ash slagging, fouling and agglomeration in...

Background: Municipal solid waste incineration (MSWI) bottom ash contains a not insignificant amount of metallic aluminum, while circulating fluidized bed combustion (CFBC) fly ash is rich in active SiO 2. To reduce the materials cost of autoclaved aerated concrete (AAC) production, these two types of solid waste could theoretically be used as the aerating agent and silica source, respectively....

While it is true that fly ash contains trace amounts of certain elements, which can be toxic in larger concentrations, it is unlikely that fly ash as used in concrete would exhibit leaching characteristics. First, the permeability of concrete containing fly ash is negligible compared to the permeability of fly ash as typically disposed. This reduced permeability prevents water or other liquids ...

This study focuses on the strength characterization of artificial fly ash aggregates produced from a pelletization process. Additionally, to improve the stability and strength properties of fly ash aggregates clay binders such as bentonite and metakaolin are added during the production. Physical properties such as specific gravity, bulk density, water absorption, gradation and individual crushi...

The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an exotic woodborer first detected in 2002 in Michigan and Ontario and is threatening the ash resource in North America. We examined the effects of light exposure and girdling on green ash (Fraxinus pennsylvanica Marsh) volatile production, and effects of light exposure, girdling, and leaf age on emerald ash bore...

We found that 180 kDa, 150 kDa (p150), 110 kDa, 100 kDa and 65 kDa (p65) proteins comprise the major Ash/Grb-2-binding proteins in bovine brain. Among these proteins, 180 kDa and 100 kDa proteins have already been identified as Sos and dynamin respectively. Here, p150 and p65 were affinity-purified with glutathione S-transferase-Ash fusion protein and their partial amino acid sequences were det...
