Boral offers a technology and service for the manufacture of ceramic lightweight aggregate LWA from coal combustion products generated by current production or recovered from landfills or ponds. The resulting aggregate can be sold and beneficially purposed in a variety of construction, agricultural, and related applications.
Ceramic Lightweight Aggregate PRODUCTION FROM FLY ASH For decades, coal combustion products CCPs have been recovered from power plants and beneficially used in applications ranging from concrete manufacturing to soil stabilization. As the environmental and performance benefits associated with CCP use have become clear,

The International Journa of Cement Composites and Lightweight Concrete, Volume 8, Number3 August 1986 Manufacturing processes of artificial lightweight aggregates from fly ash J. M. J. M. Bijen Synopsis An overview is given on manufacturing processes of artificial lightweight aggregates from fly ash.
The use of fly ash as a lightweight aggregate can offer a wide range of economic advantages not only is the source of fly ash power plants close in proximity to the demand, providing a readily available aggregate source at hand, but it can also be a muchneeded economic source in areas where natural aggregates are not widely available.
KEYWORDS fly ash, aggregate, lightweight, concrete, high strength, shrinkage . ABSTRACT . A new patented lightweight aggregates is tested. This type is given the name Flashag. The only solid raw material used to manufacture these aggregates is fly ash. The aggregates are sintered but not pelletized and the process is easy and inexpensive. This
Minergys LWA production facility was constructed as a means to beneficially reuse coal combustion fly ash from a power plant located in Oak Creek, Wis. LWA was commercially produced between 1994 and 2000, at which time the properties of the fly ash changed as a result of a new source of coal, thus allowing the fly ash to be marketed directly into the concrete industry without additional
This plant is comprised of silos, feeders, conveyors, a mixer, a pantype pelletizer, a sinterstrand, a dust collector, and fans. Figure 1 Flow sheet of artificial lightweight aggregate manufacturing process. Manufacturing Process The fly ash extracted from the silo in a given volume is fed to the mixer.
Lightweight aggregates manufactured from grinding, pelletising and sintering of MIBA were comparable to the commercial Lytag produced from coal fly ash in terms of density and water absorption, though with slightly lower strength. Blocks containing MIBA as an aggregate satisfied the requirements for a range of uses including loadbearingnon
InGlobal Resources, New Delhi focuses on sourcing proven plant and technology, which can produce Artificial Lightweight Aggregate LWA from fly ash, a waste product of coal burning power plants. The product is an excellent alternative to natural quarried aggregate, being strong, light and consistent.
lightweight fly ash aggregate manufacturing plant,flyash . The pellets are fed to a traveling grate dryer to remove moisture and then to a rotary kiln for manufacturing into lightweight aggregate. ball mill for cement More detailed
Brickwell introduces a newlyinvented process which converts waste fly ash into structural lightweight aggregate, a product which can be used to economically replace mined stone in concrete, as well as other uses. Brickwells process uses approximately 95 fly ash mixed in some cases with water and in some cases a small volume of additives.
LIGHT WEIGHT AGGREGATE Preamble InGlobal Resources, New Delhi focuses on sourcing advanced technology which can produce artificial lightweight Aggregate LWA from fly ash, a waste product of coal burning power plants. The product is an excellent alternative to natural quarried aggregate, being strong, light and consistent.
Lightweight fly ash aggregates were produced through various processes such as coldbonding, autoclaving and sintering. 3.1 Cold Bonding and simplified production techniques for manufacturing Fly ash aggregate can lead to mass production and can be an ideal substitute for the utilization in many infrastructural
Flyash Lightweight Aggregate Making Plant With the ever increasing demand for coal as an energy source there is a growing need for disposing of the waste fly ash which results from burning coal. This problem is growing especially severe in India, where Coalpowered Power Plants provide a bulk of the electricity generation.
A few companies in UK, USA, Japan etc. have introduced manufacture of such lightweight fly ash aggregate using a process of sintering the fly ash pellets at elevated temperature of around 1,200C. The process has a lot of similarities with the pyroprocessing of normal materials for manufacturing Lightweight aggregate, as described under above.
Lightweight aggregateLWA, as green building material, contrasting with the normal gravel aggregate, has the characteristic of lightweight, corrosion resistance, frost resisting, earthquake
Most fly ash is currently dumped as waste material, though new government policy in China requires that power plants have a means of disposing of the waste. The MeTech process can deal with large quantity of fly ash, not only saving agricultural land, but also reducing pollution.
