This paper report result of a study conducted on fly ash lightweight aggregates (FALA) in ed concrete cubes. The type of fly ash used is class C. The effects of using fly ash can be determine by its partial replacement of 5%, 10% and 15% in FALA.
Fly-ash cenospheres Thermal modeling abstract This study investigates the effects of mix proportion, aggregate type, and microstructures on the thermal and mechanical behaviors of structural lightweight concrete (LWC) containing lightweight aggregates and lightweight functional fillers such as fly-ash cenospheres (FAC).
lightweight aggregates made of fly ash in concreate to investigate the strength and durability of hardened con-crete, and the influence of a lightweight fly-ash aggre-gate microstructure on the properties of concrete.24–29 As expected, the compressive strength of LWAC is lower than the one produced by natural aggregate, even though

Fortunately, fly ash can be used as a beneficial additive in some applications – particularly in concrete products, where it is used as a lightweight aggregate (LWA).The benefits of using fly ash as a lightweight aggregate in concrete products are so great that the concrete industry has come to rely on this power-generated byproduct.
Fly ash is converted into coarse aggregates by 'pelletising' followed by 'sintering' actions. Powdery granules of FA can be agglomerated minerologically by sintering and then used as CA. These sintered fly ash aggregates (SFAAs) are highly porous and hence, concretes made from them aggregates would be also lightweight in nature.

considered wisely while designing the light weight geopolymer fly ash concrete mix. In current study, Lightweight Geopolymer fly ash sand (LWGFAS) was prepared by using class F fly ash and alkaline activator solution. The fly ash used in the study was from NTPC Sipat, India. The specific gravity and Blaine's fineness of fly ash was 2.12 & 382 ...
Lightweight and strong Sintered Fly-Ash low density aggregates (commonly known as LYTAG in the market) have been hugely successful lightweight construction materials for over 60 years. Made from recycled power station Fly-Ash at 1100c, these pellets are extremely strong with a honeycomb structure that traps high air volume within the aggregate.

Preparation of lightweight aggregates from fly ash. Fly ash (FA-ECJ or FA-EJ) and clay (BC) were mixed in two weight ratios − 9:1 and 4:1 (10 and 20% of beidellitic clay addition). The decision to use this amount of BC is the result of the policy of sustainable use of natural non-renewable resources relying on using a maximum amount of waste ...
alternative may be the use of lightweight aggregates, especially those aggregates which have excellent properties. One possibility is Certyd aggregate [6]. The only solid material used to manufactured these aggregate is fly ash. This special lightweight sintered aggregate is durable, lightweight and high-strength material.

•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,
