3.Sintered Fly ash. You know that fly ash is one the main mineral admixtures used in concrete. Sintered fly ash is a lightweight material which can be used as an equivalent of stone aggregates in concrete. They can widely reduce the self-weight of the structure. The sintered fly ash is used for bulk fill, land drainage, filter media, refractory ...
The lightweight aggregates were manufactured as follows: The mixture of fly ash or fly ash/slag was handily moulded in spherical shape with a 20-22 % of distilled water, and dried at 110ºC.

•THE PRODUCTION of lightweight aggregate from fly ash has received the attention of investigators throughout the world (1,2). Although a number of early attempts to produce a commercial product proved"Unsucessful, recent developments give every indication that the manufacture of fly ash aggregate is now possible. Furthermore,
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 load-bearing/non ...
The use of alternative materials for road construction is significant from both the ecological and economic perspectives. It reduces the consumption
Nu-Rock leverages the latest technology in construction materials science and production equipment to develop lightweight aggregates from landfilled and ponded fly ash. Nu-Rock's lightweight aggregates can be used to replace aggregates in ready mix concrete.
The potential of using a synthetic lightweight aggregate (SLA) in concrete is examined. The aggregates are manufactured through thermal processing using plastic to encapsulate and bind fly ash particles. Nominal maximum-size aggregates of 9.5 mm were produced with fly ash contents of 0%, 35%, and 80% by total mass of the aggregate.
The production of artificial lightweight coarse aggregate using fly ash has potential for its large-scale utilization in the construction industry and this is an area that merits attention in many ...

(2) Fly Ash. Fly ash proportioning and batching equipment shall be subject to the same controls as required for cement. Fly ash may be weighed accumulatively with the cement or separately. If weighed accumulatively, the cement shall be weighed first. (3) Water. The mixing water shall be measured by weight or by volume.
Brickwell introduces a newly-invented process that converts waste fly ash into lightweight aggregate, a product which can be used to replace the mined stone in concrete, due to stricter controls of Environmental problems as well as other uses. Brickwell's process uses approximately 95% of fly ash.
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. If the unburnt coal content in the fly ash is low, a small amount of pulverized coal is added.
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.
Durability of lightweight concretes with lightweight fly ash aggregates. This paper presents the effects of aggregate properties such as strength, porosity, water absorption, bulk density and specific gravity on the strength and durability of lightweight fly ash aggregate concrete (LWAC).
