Fly ash is the ash from burning coal
Fly ash is the ash from burning coal that is carried along with the flue gasses. Because fly ash causes air pollution, it is captured. Fly ash composition may differ significantly, depending on the type and mixture of coal and biomass that is being burned. Fly ash contains substantial amounts of silica – both amorphous and crystalline – and calcium …

Silica Fume and Fly Ash in Concrete
Project Number 206 Several earlier research projects, like project 168, for example, which were part of VGB’s major research programme, ERKOM, have already investigated to what extent fly ash from hard coal-fired power plants can be used for making high performance concretes. The combined use of two concrete additives, silica dust and fly ash, can offer considerable advantages in this …

Salt-scaling durability of fly ash concrete
Fly ash is a by-product of coal-fired power plants. This material can be used as a partial cement substitute in portland cement concrete. Use of fly ash can improve concrete durability as well as utilize an industrial by-product that would otherwise be discarded in landfills. However, research on fly ash concrete has shown that in some cases, concrete with high …

Fly Ash Characteristics From Waste-to-Energy Facilities and Processes For Ash Stabilization
SUMMARY: Despite increased efforts to prevent, reduce, reuse and recycle, the appropriate management of municipal solid waste (MSW) remains a major environmental issue. Currently, Waste-to-Energy (WTE) facilities produce clean renewable energy through the combustion of municipal solid waste in specially designed power plants equipped with the most state-of-the-art pollution control equipment. Nevertheless, the management of solid combustion residues and especially …

The Effect of Fly Ash Microspheres on the Pore Structure of Concrete
Abstract The fly ash microspheres (FAMs) formed during the mineral transformation stage in coal combustion are hollow spherical particles with a density less than water. This paper presents the results of X-ray micro-computed tomography and an automatic image analysis system of the porosity in the structure of hardened concrete with microspheres. Concrete mixtures with ordinary Portland cement and two substitution …

Mechanical-Chemical Activation of Coal Fly Ashes
Mechanical-Chemical Activation of Coal Fly Ashes: An Effective Way for Recycling and Make Cementitious Materials This paper is wholly committed to resource efficiency through the valorization of waste from other industries, and more specifically fly ash as a raw material to produce concrete-like geopolymers. In particular, this study aimed to determine the effect of the physical and chemical characteristics of …
