Effective survey methods to detect and monitor recently established, low-density infestations of emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), remain a high priority because they provide land managers and property owners with time to implement tactics to slow emerald ash borer population growth and the progression of ash mortality. We evaluated options for using gi...

in this study, the chemical characterization of solid residues, i.e., bottom ash, fly ash, and filter cake, produced from the izmit hazardous and Clinical waste incineration Plant (izAyDAS) was investigated. the izAyDAS is located in the city of kocaeli in turkey and it has been in use since 1997. Several parameters were measured, including AoX, Cl-, CN-, So4 2and selected heavy metals includin...

Typically thermal power plants are located near to surface coal mines that produce huge amount of fly ash as a waste byproduct. Disposal of fly ash causes significant economic and environmental problems. Now-a-days, research is going on for bulk utilization of fly ash. In order to increase its percentage utilization, an investigation was carried out to evaluate its potential for haul road const...

Self compacting concrete (SCC) is an innovative development of conventional concrete, which requires high binder content to increase its segregation resistance. This paper presents a comparative study on the use of different materials as binder content in SCC and their effects on the workability and strength properties are checked. Different combinations of Fly ash, Metakaolin and Saw dust ash ...

Self-compacting concrete is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction even in congested reinforcement without segregation and bleeding. In the present study self compacting concrete mixes were developed using blend of fly ash and rice husk ash. Fresh proper...

Mount St. Helens volcanic ash was incorporated into a loamy sand greenhouse soil mix to produce concentrations of 0, 0.5, 1.0, 2.0, 4.0, 8.0, 25, 50 and 100% ash. Chemical and physical properties of the various mixtures were determined. Three experiments were conducted in a greenhouse to determine if volcanic ash had any influence on root-knot nematode survival and infectivity. Tomato, Lycopers...

Two series, each consisting of seven high-volume fly ash concrete mixtures with conductive carbon fibers, were used in this investigation. The first series of the concrete mixtures contained ASTM Class C fly ash and 0, 1, 3, 5, 7.5, 10, and 20 lbs. carbon fibers per cubic yard of concrete. The second series of concrete mixtures contained high-carbon fly ash in addition to the materials used in ...

This paper investigates the effect of fineness of fly ash on the performance of cement mortar. Fly ash from thermal plant is used as partial substitute for cement. Fly ash is used as received and also processed by grinding. The study involves four replacement levels of fly ash into cement at 10%, 20%, 30% and 40% for each mix design. Mortar cubes are tested for strength, water absorption and so...
